WebJun 15, 2015 · Cryptographic hashes are used for digitally signing content for integrity validation, and are an integral part of any digital certificate. A hash function is "run against" supplied content to create a unique output set of bits (called the hash, digest, or message output). A good hash has many important cryptographic properties, including: WebMD5 Hash In cryptography, MD5 (Message-Digest algorithm 5) is a widely used cryptographic hash function with a 128-bit hash value. As an Internet standard ( RFC 1321 ), MD5 has been employed in a wide variety of security applications, and is also commonly used to check the integrity of files.
