Generate Secret Key from Password

The GenEncodedSecretKey method provides a way to produce a secret key from an arbitrarily sized password string. The secret key produced will be equal in bit length to the KeyLength. A given string passed to GenEncodedSecretKey will always produce the same key. (In other words, this is really a hash function and not a random key generator.)

    hexKey = crypt.genEncodedSecretKey("my_password","hex");

    //  Set the secret key:
    crypt.SetEncodedKey(hexKey,"hex");

    //  The hexKey is 16 bytes in length:
    printf("%s\n",hexKey);
