The Secure Hash Algorithms are a family of cryptographic hash functions published by the National Institute of Standards and Technology (NIST) as a U.S. Federal Information Processing Standard (FIPS), including: SHA-0: A retronym applied to the original version of the 160-bit hash function published in 1993 under the name "SHA".
SHA-3(Secure Hash Algorithm 3) is the latest[4]member of the Secure Hash Algorithmfamily of standards, released by NISTon August 5, 2015. [5][6][7]Although part of the same series of standards, SHA-3 is internally different from the MD5-like structureof SHA-1and SHA-2. SHA-3 is a subset of the broader cryptographic primitive family Keccak ...
SHA-2 (Secure Hash Algorithm 2) is a set of cryptographic hash functions designed by the United States National Security Agency (NSA) and first published in 2001. [ 3 ][ 4 ] They are built using the Merkle–Damgård construction, from a one-way compression function itself built using the Davies–Meyer structure from a specialized block cipher.
For the transportation of valuables, see Armored car (valuables). The Transport Layer Security (TLS) protocol provides the ability to secure communications across or inside networks. This comparison of TLS implementations compares several of the most notable libraries. There are several TLS implementations which are free software and open source.

A cryptographic hash function (CHF) is a hash algorithm (a map of an arbitrary binary string to a binary string with a fixed size of bits) that has special properties desirable for a cryptographic application: [ 1 ] the probability of a particular n {\displaystyle n} -bit output result (hash value) for a random input string ("message") is 2 − ...
The NIST hash function competition was an open competition held by the US National Institute of Standards and Technology (NIST) to develop a new hash function called SHA-3 to complement the older SHA-1 and SHA-2. The competition was formally announced in the Federal Register on November 2, 2007. [ 1 ] ". NIST is initiating an effort to develop ...
The MD5 message-digest algorithm is a widely used hash function producing a 128- bit hash value. MD5 was designed by Ronald Rivest in 1991 to replace an earlier hash function MD4, [3] and was specified in 1992 as RFC 1321. MD5 can be used as a checksum to verify data integrity against unintentional corruption. Historically it was widely used as ...
