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. @@ -1432,97 +1430,96 @@ Clipperz.Crypto.BigInt = function (aValue, aBase) { } this._internalValue = str2bigInt(value, base, 1, 1); } return this; } //============================================================================= MochiKit.Base.update(Clipperz.Crypto.BigInt.prototype, { 'clone': function() { return new Clipperz.Crypto.BigInt(this.internalValue()); }, //------------------------------------------------------------------------- 'internalValue': function () { return this._internalValue; }, //------------------------------------------------------------------------- 'isBigInt': true, //------------------------------------------------------------------------- 'toString': function(aBase) { return this.asString(aBase); }, //------------------------------------------------------------------------- 'asString': function (aBase, minimumLength) { var result; var base; if (typeof(aBase) == 'undefined') { base = 10; } else { base = aBase; } result = bigInt2str(this.internalValue(), base).toLowerCase(); if ((typeof(minimumLength) != 'undefined') && (result.length < minimumLength)) { var i, c; -//MochiKit.Logging.logDebug(">>> FIXING BigInt.asString length issue") c = (minimumLength - result.length); for (i=0; i<c; i++) { result = '0' + result; } } return result; }, //------------------------------------------------------------------------- 'asByteArray': function() { return new Clipperz.ByteArray("0x" + this.asString(16), 16); }, //------------------------------------------------------------------------- 'equals': function (aValue) { var result; if (aValue.isBigInt) { result = equals(this.internalValue(), aValue.internalValue()); } else if (typeof(aValue) == "number") { result = equalsInt(this.internalValue(), aValue); } else { throw Clipperz.Crypt.BigInt.exception.UnknownType; } return result; }, //------------------------------------------------------------------------- 'compare': function(aValue) { /* var result; var thisAsString; var aValueAsString; thisAsString = this.asString(10); aValueAsString = aValue.asString(10); result = MochiKit.Base.compare(thisAsString.length, aValueAsString.length); if (result == 0) { result = MochiKit.Base.compare(thisAsString, aValueAsString); } return result; |
