Symmetric Encryption Algorithm
The module implements the basic XTEA block encryption algorithm (`xtea_encrypt`/`xtea_decrypt`) and also provides a higher level `crypt` function which symmetrically encrypts/decrypts a variable length string using XTEA in OFB mode as a key generator. The `crypt` function does not use...
