If any one character of a message is changed, then up to half of the message digest changes.
The process involves the sender generating the message digest, then encrypting the digest using its private key to create the digital signature.
The hash function used to generate the message digest
The sender creates a message digest (also called hash value, fingerprint/thumbprint, or watermark) based on the contents of the message.
A message digest is scrambled data that is based on the password and the packet contents.
The sender encrypts the message digest under her private key.
Algorithm Type defines whether the cryptography algorithm is symmetric, asymmetric, or a message digest.
