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?

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?
