mcrypt_encrypt在php7.1中已被废弃，需要使用openssl_encrypt代替

//mdecrypt_generic版 public function encrypt_cbc($str,$iv,$encryptKey) {
$module = mcrypt\_module\_open(MCRYPT\_RIJNDAEL\_128, '', MCRYPT\_MODE\_CBC, $iv);
mcrypt_generic_init($module, $encryptKey, $iv);
//加上以下三行，可以与encrypt_openssl得到一致的加密结果，但是加密结果用mdecrypt_generic解密与decrypt_openssl结果不一致
$block = mcrypt_get_block_size(MCRYPT_RIJNDAEL_128, MCRYPT_MODE_CBC);
$pad = $block - (strlen($str) % $block);
$str .= str_repeat(chr($pad), $pad); $encrypted = mcrypt_generic($module, $str);
return base64_encode($encrypted); } //mdecrypt_generic版解密 function decrypt_cbc($str,$iv,$encryptKey) {
$module = mcrypt\_module\_open(MCRYPT\_RIJNDAEL\_128, '', MCRYPT\_MODE\_CBC, $iv);
mcrypt_generic_init($module, $encryptKey, $iv);
return mdecrypt_generic($module, base64_decode($str)); } //mcrypt_encrypt版加密 public function encrypt_hezuo($str,$localIV,$encryptKey) {
//加上以下三行，可以与encrypt_openssl得到一致的加密结果，但是加密结果用mcrypt_decrypt解密与decrypt_openssl结果不一致
$block = mcrypt_get_block_size(MCRYPT_RIJNDAEL_128, MCRYPT_MODE_CBC);
$pad = $block - (strlen($str) % $block);
$str .= str_repeat(chr($pad), $pad); return base64_encode(mcrypt_encrypt(MCRYPT\_RIJNDAEL\_128, $encryptKey, $str, MCRYPT\_MODE\_CBC, $localIV)); } //mcrypt_decrypt版解密 public function decrypt_hezuo($str,$localIV,$encryptKey) {
return mcrypt_decrypt(MCRYPT_RIJNDAEL_128, $encryptKey, base64_decode($str), MCRYPT_MODE_CBC, $localIV); } //encrypt_openssl新版加密 function encrypt_openssl($str,$localIV,$encryptKey) {
return openssl_encrypt($str, 'AES-128-CBC',$encryptKey,0,$localIV); } //decrypt_openssl新版解密 function decrypt_openssl($str,$localIV,$encryptKey) {
return openssl_decrypt($str, 'AES-128-CBC', $encryptKey, 0, $localIV); }
