Encryption and Decryption in Java
Java provides several algorithms for encryption and decryption of data, including symmetric-key algorithms and asymmetric-key algorithms. 1. **Symmetric-key algorithms:** These algorithms use the same key for both encryption and decryption. Some commonly used symmetric-key algorithms in Java include: 1. Advanced Encryption Standard (AES) 2. Data Encryption Standard (DES) 3. Blowfish 4. Twofish 2. **Asymmetric-key algorithms:** These algorithms use different keys for encryption and decryption. They are typically used for secure communication between two parties, such as in public key cryptography. Some commonly used asymmetric-key algorithms in Java include: 1. RSA (Rivest-Shamir-Adleman) 2. Elliptic Curve Cryptography (ECC) 3. Diffie-Hellman key exchange Java provides built-in classes and interfaces for implementing these encryption and decryption algorithms, such as the `javax.crypto` package for symmetric-key algorithms and the `java.security` package for asymmetric-key al...
