46 Provides String encryption/decryption and hashing.
48 Module("crypto", "0.1.2", function(mod){
50 Returns all all available encrypters.
51 @return An array of encrypters names.
53 mod.listEncrypters=function(){
55 for(var attr in String.prototype){
56 if(attr.slice(0, 8) == "encrypt_"){
57 c.push(attr.slice(8));
63 Returns all all available decrypters.
64 @return An array of decrypters names.

78 Parameters but the crypdec parameter are forwardet to the crypdec.
79 @param codec The codec to use.

112 Encrypts a string using XOR.
113 The whole String will be XORed with the key.
114 If the key is shorter than the String then it will be multiplied to fit the length of the String.
115 @param key The key to use for encryption.
117 String.prototype.encrypt_xor=function(key){
118 var e=new Array(this.length);
120 for(var i=0;i<this.length;i++){
121 e[i] = String.fromCharCode(this.charCodeAt(i) ^ key.charCodeAt(i % l));
126 Decrypts a string using XOR.
127 Since XORing is symetric it is the same as the encrypter.
128 @param key The key to use for decryption.
130 String.prototype.decrypt_xor=String.prototype.encrypt_xor;
132 Encrypts a string using the ARC4 algorithm.
133 @param key The key to use for encryption.
135 String.prototype.encrypt_rc4=function(key){
136 //generate substitution box
137 var sbox = new Array (256);

157 j = (j + sbox[i]) % 256;
161 t = (sbox[i] + sbox[j]) % 256;
162 rslt[k] = String.fromCharCode(this.charCodeAt(k) ^ sbox[t]);
164 return rslt.join("");
167 Decrypts a string using the ARC4 algorithm.
168 Since it is symetric it is the same as the encrypter.
169 @param key The key to use for decryption.
