#  Any string argument automatically begins the 30-day trial.

    sys.exit()

#  The output will be Hex, so set the EncodingMode:
crypt.put_EncodingMode("hex")

#  Set the hash algorithm:
#  Choices are: md5, sha-1, sha256, sha384, sha512, md2, haval
crypt.put_HashAlgorithm("sha-1")

#  Set the HMAC key:
crypt.SetHmacKeyEncoded("0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b","hex")
mac = crypt.hmacStringENC("Hi There")
print mac
