#  Generate a binary secret key from a password string
#  of any length.  For 128-bit encryption, GenEncodedSecretKey
#  generates the MD5 hash of the password and returns it
#  in the encoded form requested.  The 2nd param can be
#  "hex", "base64", "url", "quoted-printable", etc.

crypt.SetEncodedKey(hexKey,"hex")

#  Encrypt a string and return the binary encrypted data
#  in a base-64 encoded string.
encText = crypt.encryptStringENC(text)

print encText + "\n";

#  Decrypt and show the original string:
decryptedText = crypt.decryptStringENC(encText)

print decryptedText + "\n";
