What is cryptology?
What is cryptology? Cryptology combines the techniques of cryptography and cryptanalysis. Encryption Algorithms: MD5– this is the acronym for Message-Digest 5. It is used to create 128-bit hash values. Theoretically, hashes cannot be reversed into the original plain text. MD5 is used to encrypt passwords as well as check data integrity. MD5 is not collision resistant. Collision resistance is the difficulties in finding two values that produce the same hash values. SHA– this is the acronym for Secure Hash Algorithm. SHA algorithms are used to generate condensed representations of a message (message digest). It has various versions such as; SHA-0: produces 120-bit hash values. It was withdrawn from use due to significant flaws and replaced by SHA-1. SHA-1: produces 160-bit hash values. It is similar to earlier versions of MD5. It has cryptographic weakness and is not recommended for use since the year 2010. SHA-2: it has two hash functions namely SHA-256 and SHA-512. SHA-...
