Encryption/Decryption Implementation Methods

• Implementation methods for encryption and decryption

1. Symmetric Key Generation
   

2. Encryption

3. Decryption

SecretKeys and KeyGenerator

• SecretKeys are used in symmetric encryption algorithms and use the same keys for the encryption and decryption process
• KeyGenerator class creates the SecretKeys objects used by cipher for encryption and decryption
• KeyGenerator class (javax.crypto.KeyGenerator) ; is used to create SecretKeys
  – SecretKey myKey = keyGen.generateKey();
