Java Cryptography Architecture (JCA): A Practical Guide
Article Introduction：The core components of JCA include engine classes, security providers, algorithm parameters and key management. 1. Engine classes such as MessageDigest, Cipher, etc. define cryptographic operation interfaces; 2. Security providers such as SunJCE and BouncyCastle implement specific algorithms; 3. Keys are generated and managed through KeyGenerator and other classes; Common operations include using SHA-256 to generate message digests, AES symmetric encryption (recommended GCM or CBC mode), RSA asymmetric encryption (suitable for small data or key exchange), and DSA or RSA digital signatures; third-party providers such as BouncyCastle can be registered through Security.addProvider.

How to use the Java Cryptography Architecture (JCA)?
Article Introduction：How to implement security features using JavaCryptographyArchitecture (JCA)? The answers are as follows: 1. Select the appropriate provider, such as the built-in SUN, SunJCE or third-party BouncyCastle (BC), and add Security.addProvider() according to the needs; 2. Use KeyPairGenerator to generate key pairs, such as RSA or EC algorithm; 3. Use Cipher class to perform encryption and decryption operations, pay attention to choosing the appropriate filling method; 4. Use MessageDigest to implement message digest, such as SHA-256 for data integrity verification; 5. Use KeySto
