  In this paper it has been developed an algorithm for cryptography, using the
Mellin's transform. Cryptography is very important to protect data to ensure
that two people, using an insecure channel, may communicate in a secure way. In
the present age, ensure the communications will essential to shared data that
have to be protected. The original message is a plain text, and the encrypted
form as cipher text. The cipher text message contains all the information of
the plain text, but is cannot be read from a human without a key and a method
to decrypt it.
