2015/7/23 -SHA-256 is a member of SHA-2 cryptographic hash functions family, which usually generates 256 bits or 32 bytes HASH code from an input message.

SHA-256 is the most popular hash function in the SHA-2 family at the time of writing. It provides 128 bits of security for digital signatures and hash-only ...

A simple implementation of SHA-256 in C++ (header-only). This implementation uses little endian byte order. Using the hash_sha256.

2021/12/29 -The recommended method is to use the EVP interface, which is what SHA256() does. Based on this code here, the return value is ...

2021/11/30 -For non cryptographic hashes, you can use std::hash. Interesting note: for integers std::hash just returns the integer.

2022/8/4 -A Hash function is any function that can be used to map data of arbitrary size to values of fixed size. Values are often used to index a fixed- ...

2014/2/5 -Let's start with the core features of my C++ hashing library: computes CRC32, MD5, SHA1 and SHA256 (most common member of the SHA2 functions), ...
