MagicCrypt is a Java/PHP library to encrypt/decrpyt strings or data using Advanced Encryption Standard(AES) algorithm. It supports CBC block cipher mode, PKCS5 padding and 128 or 256-bits key length. The encrypted data will be formatted to Base64 string.

MagicCrypt

Introduction

MagicCrypt is a Java/PHP library to encrypt/decrpyt strings or data using Advanced Encryption Standard(AES) algorithm. It supports CBC block cipher mode, PKCS5 padding and 128 or 256-bits key length. The encrypted data will be formatted to Base64 string.

Usage For Java

MagicCrypt Class

MagicCrypt class is in the org.magiclen.magiccrypt package. It can help you encrypt/decrpyt strings or data using Advanced Encryption Standard(AES) algorithm.

Initialize

You have to input your AES key and key length to construct MagicCrypt object. For example,

final MagicCrypt mc = new MagicCrypt("magickey", 256);

Note. MagicCrypt only supports 128 and 256-bits key length. The larger key length, the stronger security of course. The default length is 128 bits. If you want to use 256 bits in your Java Runtime Machine (JRE), you have to install Java Cryptography Extension (JCE) first.

By the way, if you want to change Initialization Vector(IV), you can set it by passing your IV string into the third parameter to the constructor of MagicCrypt object.

Encrypt

You can use encrypt method to encrypt any string or data. For example,

final MagicCrypt mc = new MagicCrypt("magickey", 256);
System.out.println(mc.encrypt("http://magiclen.org"));

The result is,

DS/2U8royDnJDiNY2ps3f6ZoTbpZo8ZtUGYLGEjwLDQ=

Decrypt

You can use decrypt method to decrypt any encrypted string or data. For example,

final MagicCrypt mc = new MagicCrypt("magickey", 256);
System.out.println(mc.decrypt("DS/2U8royDnJDiNY2ps3f6ZoTbpZo8ZtUGYLGEjwLDQ="));

The result is,

http://magiclen.org

Base64 Class

Base64 class is in the org.magiclen.magiccrypt package. It is a clone of an implementation of Base64 in Java 8 SE adjusted for the old Java versions lower than 8.

Usage For PHP

MagicCrypt.php

Initialize

require of include MagicCrypt.php into your PHP program. Then, you have to input your AES key and key length to construct MagicCrypt object. For example,

require('MagicCrypt.php');

$mc = new MagicCrypt('magickey', 256);

If you want to change Initialization Vector(IV), you can set it by passing your IV string into the third parameter to the constructor of MagicCrypt object.

Encrypt

You can use encrypt method to encrypt any string or data. For example,

$mc = new MagicCrypt('magickey', 256);
echo $mc->encrypt('http://magiclen.org');

The result is,

DS/2U8royDnJDiNY2ps3f6ZoTbpZo8ZtUGYLGEjwLDQ=

Decrypt

You can use decrypt method to decrypt any encrypted string or data. For example,

$mc = new MagicCrypt('magickey', 256);
echo $mc->decrypt('DS/2U8royDnJDiNY2ps3f6ZoTbpZo8ZtUGYLGEjwLDQ=');

The result is,
