PHP ʖ²ἯTH º󍋼/A LVI. Mhash Functions ½鉜 These functions are intended to work with mhash. Mhash can be used to create checksums, message digests, message authentication codes, and more. This is an interface to the mhash library. mhash supports a wide variety of hash algorithms such as MD5, SHA1, GOST, and many others. For a complete list of supported hashes, refer to the documentation of mhash. The general rule is that you can access the hash algorithm from PHP with MHASH_HASHNAME. For example, to access TIGER you use the PHP constant MHASH_TIGER. Шdz To use it, download the mhash distribution from its web site and follow the included installation instructions. °²װ You need to compile PHP with the --with-mhash[=DIR] parameter to enable this extension. DIR is the mhash install directory. ԋАʱŤփ ¸À©չģ¿鎴¶¨ҥȎºΉ薃ָn¡£ ׊Դ Ѝ ¸À©չģ¿鎴¶¨ҥȎºΗʔ´ Ѝ¡£ Ԥ¶¨ҥ³£ ӉӚբЩ³£ʇӉ¸À©չģ¿鶨ҥµģ¬Ҳ´˖»ӐԚ¸À©չģ¿鱻±ҫµ½ PHP ֐£¬»򕟔ڔːЊ±±»¶¯̬¼Ӕغ󣬕␩³£²œА§¡£ Here is a list of hashes which are currently supported by mhash.
