# 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")

crypt.put_EncodingMode("base64")

# Encrypt a string and return the binary encrypted data
# in a base-64 encoded string.

print encText

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

print decryptedText
