Summary of usage examples of PHP encryption methods

PHP encryption extension library—Mhash extension library What is the Mhash extension library: Mhash is an irreversible PHP encryption extension library based on the principle of discrete mathematics. It is not enabled by default. mhash can be used to create verification values, message digests, message authentication codes, and save key information (such as passwords) without the original text. 1. Mhash extension library installation The installation of the Mhash library is similar to the installation of the Mcrypt extension library. I won’t go into more details here. You can refer to the previous article "PHP Encryption Extension Library—Mcrypt Extension Library"! 2. Mhash extension library constants The Mhash library supports multiple hashing algorithms such as MD5, SHA, CRC32, etc. You can use the mhash_count() and mhash_get_hash_name() functions to output the supported algorithm names. Let’s take a look at the sample code:
