PHP combined with MD5 implementation of encryption and decryption method, PHP combined with MD5 encryption decryption

This paper describes the encryption and decryption method implemented by PHP combined with MD5. Share to everyone for your reference, as follows:

Recently in the collation of the code found a good thing, combined with MD5 encryption and decryption algorithm. On the internet about PHP combined with MD5 encryption, decryption algorithm is less, in fact, PHP manual inside there, change a change on the line. In this post, with this algorithm to load a PHP module MCrypt, or can not be used.

Cryptographic function String2secret ($str) {$key = "123"; $td = Mcrypt_module_open (Mcrypt_des, ' ', ' ECB ', '); $iv = Mcrypt_create_iv (Mcrypt_enc_get_iv_size ($TD), Mcrypt_rand); $ks = Mcrypt_enc_get_key_size ($TD); $key = substr (MD5 ($key), 0, $ks); Mcrypt_generic_init ($TD, $key, $IV); $secret = Mcrypt_generic ($TD, $STR); Mcrypt_generic_deinit ($TD); Mcrypt_module_close ($TD); return $secret;} Decrypt function secret2string ($sec) {$key = "123"; $td = Mcrypt_module_open (Mcrypt_des, ' ', ' ECB ', '); $iv = Mcrypt_create_iv (Mcrypt_enc_get_iv_size ($TD), Mcrypt_rand); $ks = Mcrypt_enc_get_key_size ($TD); $key = substr (MD5 ($key), 0, $ks); Mcrypt_generic_init ($TD, $key, $IV); $string = Mdecrypt_generic ($TD, $sec); Mcrypt_generic_deinit ($TD); Mcrypt_module_close ($TD); Return trim ($string);} Echo secret2string (String2secret ("11111111111111111")); Display result is 11111111111111111echo string2secret ("11111111111111111"); Garbled display

PHP often uses the Add decryption function, Base64_encode,base64_decode.
