本文实例讲述了php实现基于openssl的加密解密方法。分享给大家供大家参考,具体如下:
通过openssl加密解密方法
1. openssl加密方法:
1
2
3
4
5
6
7
8

function encrypt( $id ){
$id =serialize( $id );
$key = "1112121212121212121212" ;
$data [ 'iv' ]= base64_encode ( substr ( 'fdakinel;injajdji' ,0,16));
$data [ 'value' ]=openssl_encrypt( $id , 'AES-256-CBC' , $key ,0, base64_decode ( $data [ 'iv' ]));
$encrypt = base64_encode (json_encode( $data ));
return $encrypt ;
}

function decrypt( $encrypt )
{
$key = '1112121212121212121212' ; //解密钥匙
$encrypt = json_decode( base64_decode ( $encrypt ), true);
$iv = base64_decode ( $encrypt [ 'iv' ]);
$decrypt = openssl_decrypt( $encrypt [ 'value' ], 'AES-256-CBC' , $key , 0, $iv );
$id = unserialize( $decrypt );
if ( $id ){
return $id ;
} else {
return 0;
}
}
