Digital Signature with openSSL on the GNU/Linux Console

At very first, a private/public key pair is being created.
Afterwards, a sample message, which gets created, is hashed, that is, creating a digital fingerprint from it. Thereafter, this message hash is encoded using the private key, which then is simply attached to the plain message. The receiver of this message may now use the public key of the sender to decode the hash and see if the message sent is authentic.
