Java Cryptography | Part 2

Java Cryptography | Part 2: In today’s environment, information security is crucial for everyone. Security needs vary widely from protecting social security numbers to guarding corporate strategy. Information espionage can occur at all levels. A human resources employee or manager takes employee personnel files home to work on them and unfortunately loses them or they get stolen. An employee’s notes to a supervisor regarding a case are intercepted and read via monitoring software by an outside hacker. The resulting damages can be costly and could be avoided by protecting assets with encryption technology.
This article demonstrates the implementation of the Cryptography header cited in the previous article and illustrates how to encrypt and digitally sign files using a hybrid combination of asymmetric public/private key encryption and symmetric encryption. A symmetric key is used to encrypt the file and the asymmetric public key encrypts the symmetric key. The asymmetric private key decrypts the symmetric key which in turn is used to decrypt the encrypted file.
