* * This is really a "preview" of my forthcoming encryption library. The * real deal will be much snazzier and cook your breakfast too. Heck, it * might even have comments, too! For now, if you'd like to get into the * encryption scene a bit, feel free to take this baby for a spin. The * simple interface is documented below. Dig into the code if you want * to try some more advanced things. * * Expect all of this to change significantly before the final release! * * Usage: * * This library implements the RC5 encryption algorithm, originally * developed by RSA, Inc. It encrypts and decrypts data as text * strings: if your data is not yet in text format, you'll have to * provide your own method for translating it to and from text. * In the specific case of encrypting savefiles, you'll probably * want to look at savefile.ExportText() and savefile.ImportText(). * * RC5 encryption uses a key, or password, to secure data against * attack. To encrypt a plain text string p using key k and store * it as cipher text c, simply call: * * c = RC5_Encrypt(p, k) * * Similarly, to decrypt a cipher text string c using key k into plain * text p, call: * * p = RC5_Decrypt(c, k) * * By definition, RC5_Decrypt(RC5_Encrypt(p, k), k) == p. * ************************************************************************** * * You can compile this library standalone to get a simple demo world. * Examine the demo code, play with the verbs, have fun. * | |
