Şunu aradınız:: habrás desencriptado (İspanyolca - Çince (Modern))

actualmente php no soporta el encriptado / desencriptado de flujos de bits.
here is a list of ciphers which are currently supported by the mcrypt extension. for a complete list of supported ciphers, see the defines at the end of mcrypt.h. the general rule with the mcrypt-2.2.x api is that you can access the cipher from php with mcrypt_ciphername. with the libmcrypt-2.4.x and libmcrypt-2.5.x api these constants also work, but it is possible to specify the name of the cipher as a string with a call to mcrypt_module_open().

no hay función de desencriptado porque crypt() utiliza un algoritmo de una sola vía.
?php $password = crypt("my1stpassword"); # let salt be generated # you should pass the entire results of crypt() as the salt for comparing a # password, to avoid problems when different hashing algorithms are used. (as # it says above, standard des-based password hashing uses a 2-character salt, # but md5-based hashing uses 12.) if (crypt($user_input,$password) == $password) {echo "password verified!";}?
