Cryptography with Java

This project contains samples on how to do cryptographic operations in Java using the BouncyCastle libray.

These classes are not actual tests, its just a convinient way to run individual methods in an IDE

This is what you can expect to find the included classes:

1. ProvidersTest: A demo of how JCE uses crypto providers and how external providers can be added
2. HashingTest : A demo of creating and validating crypto hash. Also includes an example of MD5 collision
3. EncryptionTest : Includes example of symmetrical and asymmetrical encryption and decryption
4. KeystoreAndKeysTest : Demonstartes how crypto keys are generated and written into a keystore as well as accessed from different keystores. Includes samples of creating keystores, genrating X509 certificates and certificate chains, generating CSR and signing issued certificate with root certificate.
5. DigitalSignatureTest : Shows how PKCS1 and PKCS7 digital signatures can be generated and verified.
