Cryptografy

"Data security is easy"

Note: I'm not a security specialist, so be careful before use this package in critical environments.

What is the goal?

Cryptografy is a package that aimed at making easier the use of standard encryptions of Java SE 6.

The following encryptions are currently implemented:

Symmetrics:

1. AES
2. Blowfish
3. DES
4. DESede
5. PBEWithMD5AndDES
6. PBEWithSHA1AndDESede
7. RC2
8. RC4

Asymmetrics:

1. RSA 1024 bits

How can I use it?

Is very simple encript/decript a String or byte[], for sample:

Using Symmetric Algorithms: SymmetricCryptFactory factory = SymmetricCryptFactory.getInstance(); //Encrypt SymmetricCrypter pbeWithMd5AndDes = factory.getCryptografy(SymmetricAlgorithm.PBEWithMD5AndDES); pbeWithMd5AndDes.generateKey(); String encrypted = pbeWithMd5AndDes.encrypt("input"); byte[] key = pbeWithMd5AndDes.getSerializedKey();

//Decrypt
SymmetricCrypter anotherPbeWithMd5AndDes = factory.getCryptografy(SymmetricAlgorithm.PBEWithMD5AndDES, key);
String decryptedAgain = anotherPbeWithMd5AndDes.decrypt(encrypted);

Using Asymetric algorithms: AsymmetricCryptFactory factory = AsymmetricCryptFactory.getInstance(); //Encrypt AsymmetricCrypter rsa = factory.getCryptografy(AsymmetricAlgorithm.RSA_1024bits); rsa.generateKeys(); EncryptSet es = rsa.encrypt("input"); String encrypted = es.getContents(); String encryptedKey = es.getEncryptedKey(); byte[] pubK = rsa.getSerializedPublicKey();

//Decrypt
AsymmetricCrypter rsap = factory.getCryptografy(AsymmetricAlgorithm.RSA_1024bits,pubK);
String decryptedAgain = rsap.decrypt(encripted, encryptedKey);
