TLS/SSL and crypto library. Contribute to openssl/openssl development by creating an account on GitHub. The HashAlgorithm class is the base class for hash algorithms including MD5, RIPEMD160, SHA1, SHA256, SHA384, and SHA512. The ComputeHash method of HashAlgorithm computes a hash. It takes a byte array or stream as an input and returns a hash in the form of a byte array of 256 bits.

SHA256简介SHA256是SHA-2下细分出的一种算法SHA-2，名称来自于安全散列算法2（英语：Secure Hash Algorithm 2）的缩写，一种密码散列函数算法标准，由美国国家安全局研发，属于SHA算法之一，是SHA-1的后继者。SHA-2下又可再分为六个不同的算法标准包括了：SHA-224、SHA-256、SHA-384、SHA-512、SHA-512/2 2021. 2. 28. · De SHA-familie (Secure Hash Algorithm) is een verzameling gerelateerde cryptografische hashfuncties ontworpen door de Amerikaanse National Security Agency en gepubliceerd door het Amerikaanse National Institute of Standards and Technology..

· I have been looking for a SHA-256 implementation in C with no dependencies (preferably self-contained in a single C-file) with a permissive license but found none to my liking. Since the Wikipedia pseudo-code looked extremely well-specified, and since generating test vectors is so easy with sha256sum, I decided to make my own implementation and release it in the public domain on GitHub. SHA-256 (256 bit) is part of SHA-2 set of cryptographic hash functions, designed by the U.S. National Security Agency (NSA) and published in 2001 by the NIST as a U.S. Federal Information Processing Standard (FIPS).
