Using mdecrypt_generic() to Decrypt Data in PHP
This article explains the PHP mdecrypt_generic() function, its parameters, and provides a complete example that demonstrates opening an encryption module, encrypting data, decrypting it back, and verifying the result while handling necessary initialization and cleanup steps.
The mdecrypt_generic() function decrypts data encrypted with the mcrypt extension; because of possible padding, the returned string length may differ from the original plaintext.
Parameters
$td : the encryption descriptor created by mcrypt_module_open() .
$data : the ciphertext to be decrypted.
Example usage
The script encrypts $plain_text , then decrypts it back, compares the result with the original, and outputs "ok" if they match or "error" otherwise, demonstrating proper initialization, deinitialization, and module closure.
