MD5 (Message-Digest algorithm 5) was developed by Professor Ronald L. Rivest and is a widely used cryptographic hash function with a 128-bit hash value. As an Internet standard MD5 has been employed in a wide variety of security applications, and is also commonly used to check the integrity of files. An MD5 hash is typically expressed as a 32-character hexadecimal number.
