-/* rijndael.js Rijndael Reference Implementation
-
- This is a modified version of the software described below,
- produced in September 2003 by John Walker for use in the
- JavsScrypt browser-based encryption package. The principal
- changes are replacing the original getRandomBytes function with
- one which calls our pseudorandom generator (which must
- be instantiated and seeded before the first call on getRandomBytes),
- and changing keySizeInBits to 256. Some code not required by the
- JavsScrypt application has been commented out. Please see
- http://www.fourmilab.ch/javascrypt/ for further information on
- JavaScrypt.
-
- The following is the original copyright and application
- information.
-

-
- This software is provided as-is, without express or implied warranty.
- Permission to use, copy, modify, distribute or sell this software, with or
- without fee, for any purpose and by any individual or organization, is hereby
- granted, provided that the above copyright notice and this paragraph appear
- in all copies. Distribution as a part of an application or binary must
- include the above copyright notice in the documentation and/or other materials
- provided with the application or distribution.
-
- As the above disclaimer notes, you are free to use this code however you
- want. However, I would request that you send me an email
- (fritz /at/ cs /dot/ ucsd /dot/ edu) to say hi if you find this code useful
- or instructional. Seeing that people are using the code acts as
- encouragement for me to continue development. If you *really* want to thank
- me you can buy the book I wrote with Thomas Powell, _JavaScript:
- _The_Complete_Reference_ :)
-
- This code is an UNOPTIMIZED REFERENCE implementation of Rijndael.
- If there is sufficient interest I can write an optimized (word-based,
- table-driven) version, although you might want to consider using a
- compiled language if speed is critical to your application. As it stands,
- one run of the monte carlo test (10,000 encryptions) can take up to
- several minutes, depending upon your processor. You shouldn't expect more
- than a few kilobytes per second in throughput.
-
- Also note that there is very little error checking in these functions.
- Doing proper error checking is always a good idea, but the ideal
- implementation (using the instanceof operator and exceptions) requires
- IE5+/NS6+, and I've chosen to implement this code so that it is compatible
- with IE4/NS4.
-
- And finally, because JavaScript doesn't have an explicit byte/char data
- type (although JavaScript 2.0 most likely will), when I refer to "byte"
- in this code I generally mean "32 bit integer with value in the interval
- [0,255]" which I treat as a byte.
-
- See http://www-cse.ucsd.edu/~fritz/rijndael.html for more documentation
- of the (very simple) API provided by this code.

-// Big Integer Library v. 5.0
-// Created 2000, last modified 2006
-// Leemon Baird
-// www.leemon.com
-//
-// This file is public domain. You can use it for any purpose without restriction.
-// I do not guarantee that it is correct, so use it at your own risk. If you use
-// it for something interesting, I'd appreciate hearing about it. If you find
-// any bugs or make any improvements, I'd appreciate hearing about those too.
-// It would also be nice if my name and address were left in the comments.
-// But none of that is required.
-//
-// This code defines a bigInt library for arbitrary-precision integers.
-// A bigInt is an array of integers storing the value in chunks of bpe bits,
-// little endian (buff[0] is the least significant word).
-// Negative bigInts are stored two's complement.
-// Some functions assume their parameters have at least one leading zero element.
-// Functions with an underscore at the end of the name have unpredictable behavior in case of overflow,
-// so the caller must make sure overflow won't happen.
-// For each function where a parameter is modified, that same
-// variable must not be used as another argument too.
-// So, you cannot square x by doing multMod_(x,x,n).
-// You must use squareMod_(x,n) instead, or do y=dup(x); multMod_(x,y,n).
-//
-// These functions are designed to avoid frequent dynamic memory allocation in the inner loop.
-// For most functions, if it needs a BigInt as a local variable it will actually use
-// a global, and will only allocate to it when it's not the right size. This ensures
-// that when a function is called repeatedly with same-sized parameters, it only allocates
-// memory on the first call.
-//
-// Note that for cryptographic purposes, the calls to Math.random() must
-// be replaced with calls to a better pseudorandom number generator.
-//
-// In the following, "bigInt" means a bigInt with at least one leading zero element,
-// and "integer" means a nonnegative integer less than radix. In some cases, integer
-// can be negative. Negative bigInts are 2s complement.
-//
-// The following functions do not modify their inputs, but dynamically allocate memory every time they are called:
-//
-// function bigInt2str(x,base) //convert a bigInt into a string in a given base, from base 2 up to base 95
-// function dup(x) //returns a copy of bigInt x
-// function findPrimes(n) //return array of all primes less than integer n
-// function int2bigInt(t,n,m) //convert integer t to a bigInt with at least n bits and m array elements
-// function int2bigInt(s,b,n,m) //convert string s in base b to a bigInt with at least n bits and m array elements
-// function trim(x,k) //return a copy of x with exactly k leading zero elements
-//
-// The following functions do not modify their inputs, so there is never a problem with the result being too big:
-//
-// function bitSize(x) //returns how many bits long the bigInt x is, not counting leading zeros
-// function equals(x,y) //is the bigInt x equal to the bigint y?
-// function equalsInt(x,y) //is bigint x equal to integer y?
-// function greater(x,y) //is x>y? (x and y are nonnegative bigInts)
-// function greaterShift(x,y,shift)//is (x <<(shift*bpe)) > y?
-// function isZero(x) //is the bigInt x equal to zero?
-// function millerRabin(x,b) //does one round of Miller-Rabin base integer b say that bigInt x is possibly prime (as opposed to definitely composite)?

-// The following functions are based on algorithms from the _Handbook of Applied Cryptography_
-// powMod_() = algorithm 14.94, Montgomery exponentiation
-// eGCD_,inverseMod_() = algorithm 14.61, Binary extended GCD_
-// GCD_() = algorothm 14.57, Lehmer's algorithm
-// mont_() = algorithm 14.36, Montgomery multiplication
-// divide_() = algorithm 14.20 Multiple-precision division
-// squareMod_() = algorithm 14.16 Multiple-precision squaring
-// randTruePrime_() = algorithm 4.62, Maurer's algorithm
-// millerRabin() = algorithm 4.24, Miller-Rabin algorithm
-//
-// Profiling shows:
-// randTruePrime_() spends:
-// 10% of its time in calls to powMod_()
-// 85% of its time in calls to millerRabin()
-// millerRabin() spends:
-// 99% of its time in calls to powMod_() (always with a base of 2)
-// powMod_() spends:
-// 94% of its time in calls to mont_() (almost always with x==y)
-//
-// This suggests there are several ways to speed up this library slightly:
-// - convert powMod_ to use a Montgomery form of k-ary window (or maybe a Montgomery form of sliding window)
-// -- this should especially focus on being fast when raising 2 to a power mod n
-// - convert randTruePrime_() to use a minimum r of 1/3 instead of 1/2 with the appropriate change to the test
-// - tune the parameters in randTruePrime_(), including c, m, and recLimit
-// - speed up the single loop in mont_() that takes 95% of the runtime, perhaps by reducing checking
-// within the loop when all the parameters are the same length.
-//
-// There are several ideas that look like they wouldn't help much at all:
-// - replacing trial division in randTruePrime_() with a sieve (that speeds up something taking almost no time anyway)
-// - increase bpe from 15 to 30 (that would help if we had a 32*32->64 multiplier, but not with JavaScript's 32*32->32)
-// - speeding up mont_(x,y,n,np) when x==y by doing a non-modular, non-Montgomery square
-// followed by a Montgomery reduction. The intermediate answer will be twice as long as x, so that
-// method would be slower. This is unfortunate because the code currently spends almost all of its time
-// doing mont_(x,x,...), both for randTruePrime_() and powMod_(). A faster method for Montgomery squaring
-// would have a large impact on the speed of randTruePrime_() and powMod_(). HAC has a couple of poorly-worded
-// sentences that seem to imply it's faster to do a non-modular square followed by a single
-// Montgomery reduction, but that's obviously wrong.

-// Big Integer Library v. 5.0
-// Created 2000, last modified 2006
-// Leemon Baird
-// www.leemon.com
-//
-// This file is public domain. You can use it for any purpose without restriction.
-// I do not guarantee that it is correct, so use it at your own risk. If you use
-// it for something interesting, I'd appreciate hearing about it. If you find
-// any bugs or make any improvements, I'd appreciate hearing about those too.
-// It would also be nice if my name and address were left in the comments.
-// But none of that is required.
-//
-// This code defines a bigInt library for arbitrary-precision integers.
-// A bigInt is an array of integers storing the value in chunks of bpe bits,
-// little endian (buff[0] is the least significant word).
-// Negative bigInts are stored two's complement.
-// Some functions assume their parameters have at least one leading zero element.
-// Functions with an underscore at the end of the name have unpredictable behavior in case of overflow,
-// so the caller must make sure overflow won't happen.
-// For each function where a parameter is modified, that same
-// variable must not be used as another argument too.
-// So, you cannot square x by doing multMod_(x,x,n).
-// You must use squareMod_(x,n) instead, or do y=dup(x); multMod_(x,y,n).
-//
-// These functions are designed to avoid frequent dynamic memory allocation in the inner loop.
-// For most functions, if it needs a BigInt as a local variable it will actually use
-// a global, and will only allocate to it when it's not the right size. This ensures
-// that when a function is called repeatedly with same-sized parameters, it only allocates
-// memory on the first call.
-//
-// Note that for cryptographic purposes, the calls to Math.random() must
-// be replaced with calls to a better pseudorandom number generator.
-//
-// In the following, "bigInt" means a bigInt with at least one leading zero element,
-// and "integer" means a nonnegative integer less than radix. In some cases, integer
-// can be negative. Negative bigInts are 2s complement.
-//
-// The following functions do not modify their inputs, but dynamically allocate memory every time they are called:
-//
-// function bigInt2str(x,base) //convert a bigInt into a string in a given base, from base 2 up to base 95
-// function dup(x) //returns a copy of bigInt x
-// function findPrimes(n) //return array of all primes less than integer n
-// function int2bigInt(t,n,m) //convert integer t to a bigInt with at least n bits and m array elements
-// function str2bigInt(s,b,n,m) //convert string s in base b to a bigInt with at least n bits and m array elements
-// function trim(x,k) //return a copy of x with exactly k leading zero elements
-//
-// The following functions do not modify their inputs, so there is never a problem with the result being too big:
-//
-// function bitSize(x) //returns how many bits long the bigInt x is, not counting leading zeros
-// function equals(x,y) //is the bigInt x equal to the bigint y?
-// function equalsInt(x,y) //is bigint x equal to integer y?
-// function greater(x,y) //is x>y? (x and y are nonnegative bigInts)
-// function greaterShift(x,y,shift)//is (x <<(shift*bpe)) > y?
-// function isZero(x) //is the bigInt x equal to zero?
-// function millerRabin(x,b) //does one round of Miller-Rabin base integer b say that bigInt x is possibly prime (as opposed to definitely composite)?
-// function modInt(x,n) //return x mod n for bigInt x and integer n.
-// function negative(x) //is bigInt x negative?
-//
-// The following functions do not modify their inputs, but allocate memory and call functions with underscores
-//
-// function add(x,y) //return (x+y) for bigInts x and y.
-// function addInt(x,n) //return (x+n) where x is a bigInt and n is an integer.
-// function expand(x,n) //return a copy of x with at least n elements, adding leading zeros if needed
-// function inverseMod(x,n) //return (x**(-1) mod n) for bigInts x and n. If no inverse exists, it returns null
-// function mod(x,n) //return a new bigInt equal to (x mod n) for bigInts x and n.
-// function mult(x,y) //return x*y for bigInts x and y. This is faster when y<x.
-// function multMod(x,y,n) //return (x*y mod n) for bigInts x,y,n. For greater speed, let y<x.
-// function powMod(x,y,n) //return (x**y mod n) where x,y,n are bigInts and ** is exponentiation. 0**0=1. Faster for odd n.
-// function randTruePrime(k) //return a new, random, k-bit, true prime using Maurer's algorithm.
-// function sub(x,y) //return (x-y) for bigInts x and y. Negative answers will be 2s complement
-//
-// The following functions write a bigInt result to one of the parameters, but
-// the result is never bigger than the original, so there can't be overflow problems:
-//
-// function divInt_(x,n) //do x=floor(x/n) for bigInt x and integer n, and return the remainder
-// function GCD_(x,y) //set x to the greatest common divisor of bigInts x and y, (y is destroyed).
-// function halve_(x) //do x=floor(|x|/2)*sgn(x) for bigInt x in 2's complement
-// function mod_(x,n) //do x=x mod n for bigInts x and n.
-// function rightShift_(x,n) //right shift bigInt x by n bits. 0 <= n < bpe.
-//
-// The following functions write a bigInt result to one of the parameters. The caller is responsible for
-// ensuring it is large enough to hold the result.
-//
-// function addInt_(x,n) //do x=x+n where x is a bigInt and n is an integer
-// function add_(x,y) //do x=x+y for bigInts x and y
-// function addShift_(x,y,ys) //do x=x+(y<<(ys*bpe))
-// function copy_(x,y) //do x=y on bigInts x and y
-// function copyInt_(x,n) //do x=n on bigInt x and integer n
-// function carry_(x) //do carries and borrows so each element of the bigInt x fits in bpe bits.
-// function divide_(x,y,q,r) //divide_ x by y giving quotient q and remainder r
-// function eGCD_(x,y,d,a,b) //sets a,b,d to positive big integers such that d = GCD_(x,y) = a*x-b*y
-// function inverseMod_(x,n) //do x=x**(-1) mod n, for bigInts x and n. Returns 1 (0) if inverse does (doesn't) exist
-// function inverseModInt_(x,n) //return x**(-1) mod n, for integers x and n. Return 0 if there is no inverse
-// function leftShift_(x,n) //left shift bigInt x by n bits. n<bpe.
-// function linComb_(x,y,a,b) //do x=a*x+b*y for bigInts x and y and integers a and b
-// function linCombShift_(x,y,b,ys) //do x=x+b*(y<<(ys*bpe)) for bigInts x and y, and integers b and ys
-// function mont_(x,y,n,np) //Montgomery multiplication (see comments where the function is defined)
-// function mult_(x,y) //do x=x*y for bigInts x and y.
-// function multInt_(x,n) //do x=x*n where x is a bigInt and n is an integer.
-// function multMod_(x,y,n) //do x=x*y mod n for bigInts x,y,n.
-// function powMod_(x,y,n) //do x=x**y mod n, where x,y,n are bigInts (n is odd) and ** is exponentiation. 0**0=1.
-// function randBigInt_(b,n,s) //do b = an n-bit random BigInt. if s=1, then nth bit (most significant bit) is set to 1. n>=1.
-// function randTruePrime_(ans,k) //do ans = a random k-bit true random prime (not just probable prime) with 1 in the msb.
-// function squareMod_(x,n) //do x=x*x mod n for bigInts x,n
-// function sub_(x,y) //do x=x-y for bigInts x and y. Negative answers will be 2s complement.
-// function subShift_(x,y,ys) //do x=x-(y<<(ys*bpe)). Negative answers will be 2s complement.
-//
-// The following functions are based on algorithms from the _Handbook of Applied Cryptography_
-// powMod_() = algorithm 14.94, Montgomery exponentiation
-// eGCD_,inverseMod_() = algorithm 14.61, Binary extended GCD_
-// GCD_() = algorothm 14.57, Lehmer's algorithm
-// mont_() = algorithm 14.36, Montgomery multiplication
-// divide_() = algorithm 14.20 Multiple-precision division
-// squareMod_() = algorithm 14.16 Multiple-precision squaring
-// randTruePrime_() = algorithm 4.62, Maurer's algorithm
-// millerRabin() = algorithm 4.24, Miller-Rabin algorithm
-//
-// Profiling shows:
-// randTruePrime_() spends:
-// 10% of its time in calls to powMod_()
-// 85% of its time in calls to millerRabin()
-// millerRabin() spends:
-// 99% of its time in calls to powMod_() (always with a base of 2)
-// powMod_() spends:
-// 94% of its time in calls to mont_() (almost always with x==y)
-//
-// This suggests there are several ways to speed up this library slightly:
-// - convert powMod_ to use a Montgomery form of k-ary window (or maybe a Montgomery form of sliding window)
-// -- this should especially focus on being fast when raising 2 to a power mod n
-// - convert randTruePrime_() to use a minimum r of 1/3 instead of 1/2 with the appropriate change to the test
-// - tune the parameters in randTruePrime_(), including c, m, and recLimit
-// - speed up the single loop in mont_() that takes 95% of the runtime, perhaps by reducing checking
-// within the loop when all the parameters are the same length.
-//
-// There are several ideas that look like they wouldn't help much at all:
-// - replacing trial division in randTruePrime_() with a sieve (that speeds up something taking almost no time anyway)
-// - increase bpe from 15 to 30 (that would help if we had a 32*32->64 multiplier, but not with JavaScript's 32*32->32)
-// - speeding up mont_(x,y,n,np) when x==y by doing a non-modular, non-Montgomery square
-// followed by a Montgomery reduction. The intermediate answer will be twice as long as x, so that
-// method would be slower. This is unfortunate because the code currently spends almost all of its time
-// doing mont_(x,x,...), both for randTruePrime_() and powMod_(). A faster method for Montgomery squaring
-// would have a large impact on the speed of randTruePrime_() and powMod_(). HAC has a couple of poorly-worded
-// sentences that seem to imply it's faster to do a non-modular square followed by a single
-// Montgomery reduction, but that's obviously wrong.
