Hash sha 256 php

SHA256 is a part of the SHA-2 (Secure Hash Algorithm 2) family of one-way cryptographic functions, developed in 2001 by the United States National Security Agency (NSA). Hashing functions are cryptographic devices that take as input any string of characters or a file of any type, and then output a computed collision-resistant hash.

down. 56 Michiel Thalen, Thalent ¶ 4 years ago. As Michael uggests we should take care not to compare the hash using == (or ===). Since PHP version 5.6 we can now use hash_equals().

The hash_hmac() function is used to generate keyed hash value using HMAC method. HMAC stands for keyed-hash message authentication code or hash-based message authentication code. It makes use of cryptographic hash function like md5, sha-256 and a secret key to return the message digest hash of the given data. How to calculate sha256 hash in PHP with hash function. Since version 5.1.2 PHP contains function hash() that you can use to get sha256 hash from strings. The sha1() function calculates the SHA-1 hash of a string. The sha1() function uses the US Secure Hash Algorithm 1.
