分享下php对称加密算法的实现代码。
KEY 是之前定义的常量
Mcrypt::::('ROOT') or ('Access Denied' encrypt( (mcrypt_encrypt(MCRYPT_RIJNDAEL_256, (), , MCRYPT_MODE_ECB, mcrypt_create_iv(mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256, MCRYPT_MODE_ECB), decrypt( mcrypt_decrypt(MCRYPT_RIJNDAEL_256, (), (), MCRYPT_MODE_ECB, mcrypt_create_iv(mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256, MCRYPT_MODE_ECB),
