Cryptographic hashes

A cryptographic hash function is a procedure that takes an arbitrary block of data and returns a fixed-size bit string, such that an accidental or intentional change to the data will change the hash value. The ideal cryptographic hash function has four main properties: it is easy to compute the hash value for any given message, it is difficult to find a message that has a given hash, it is difficult to modify a message without changing its hash, and it is difficult to find two different messages with the same hash.

A list of Cryptographic hashes

  • MD4 hash

    MD4 is a message digest algorithm designed by Professor Ronald Rivest of MIT in 1990. It implements a cryptographic hash function for use in message integrity checks. The digest length is 128 bits. The algorithm has influenced later designs, such as the MD5, SHA and RIPEMD algorithms. MD4 is also used to compute NT-hash password digests on Microsoft Windows NT, XP and Vista.

  • MD5 hash

    In cryptography, MD5 (Message-Digest algorithm 5) is a widely used cryptographic hash function with a 128-bit hash value. An MD5 hash is typically expressed as a 32 digit hexadecimal number.

  • RIPEMD160 hash

    The 160-bit RIPEMD-160 hashes (also termed RIPE message digests) are typically represented as 40-digit hexadecimal numbers. RIPEMD-160 (RACE Integrity Primitives Evaluation Message Digest) is a 160-bit message digest algorithm (and cryptographic hash function). It is an improved version of RIPEMD, which in turn was based upon the design principles used in MD4, and is similar in performance to the more popular SHA-1.

  • SHA-1 hash

    SHA-1 is a widely used cryptographic hash function with a 128-bit hash value. SHA-1 has been employed in a wide variety of security applications, and is also commonly used to check the integrity of files. An SHA-1 hash is typically expressed as a 32 digit hexadecimal number.

  • SHA-256 hash

    SHA-256 is a cryptographic hash function with a 256-bit hash value. It is related to SHA-1 (which only has a 128-bit hash value). An SHA-256 hash is typically expressed as a 64 digit hexadecimal number.

  • SHA-512 hash

    SHA-512 is a cryptographic hash function with a 512-bit hash value. It is related to SHA-1 (which only has a 128-bit hash value) and SHA-256 (which has a 256-bit hash value). An SHA-512 hash is typically expressed as a 128 digit hexadecimal number.
