This tutorial help to encrypt and decrypt string using cryptojs and php.
Cryptojs is very popular library which is used to convert string data into encrypted text and vise versa.
I am using below files for decrypt string in php
Angular application — Angularjs application convert string and send to php application for decrypt data.
index.php – This file responsible to decrypt string using
mcrypt_decrypt and display data.
We are using cryptojs Hex method to encode
iv in angularjs application. I am using below key and iv –
- key : 0123456789abcdef0123456789abcdef
- iv : abcdef9876543210abcdef9876543210
- Encrypted string : MwOfGGCYPBEpQ0ImKQsgyA==
Above salt string is public key which is available only for both party server and front-end side.
Decrypt String in PHP using Cryptojs and AES
There are following php code help to convert encrypted data into plain string.
<?php $key = pack(“H*”, “0123456789abcdef0123456789abcdef”); $iv = pack(“H*”, “abcdef9876543210abcdef9876543210”); $encrypted = base64_decode(‘MwOfGGCYPBEpQ0ImKQsgyA==’); $decrypt_string = mcrypt_decrypt(MCRYPT_RIJNDAEL_128, $key, $encrypted, MCRYPT_MODE_CBC, $iv); echo $decrypt_string; ?>
$key = pack(“H*”, “0123456789abcdef0123456789abcdef”);
$iv = pack(“H*”, “abcdef9876543210abcdef9876543210”);
$encrypted = base64_decode(‘MwOfGGCYPBEpQ0ImKQsgyA==’);
$decrypt_string = mcrypt_decrypt(MCRYPT_RIJNDAEL_128, $key, $encrypted, MCRYPT_MODE_CBC, $iv);
I am using
mcrypt_decrypt() method for decrypt data and
MCRYPT_RIJNDAEL_128 cipher key.
