Private key and Public Key Pair Generation
This chapter provides tutorial notes and example codes on private key and public key pair generation. Topics include public key encryption algorithms, RSA, DSA and DiffieHellman; private key and public key pair generation class and sample program; RSA, DSA, and DiffieHellman key pair samples.
Private and Public Keys and Related Interfaces
KeyPair and KeyPairGenerator Classes
Key Pair Sample Program - JcaKeyPair.java
DSA Private Key and Public Key Pair Sample
RSA Private Key and Public Key Pair Sample
DiffieHellman Private Key and Public Key Pair Sample
- JDK supports 3 algorithms to generate private and public pairs:
RSA, DSA, and DiffieHellman.
- JDK allows you to store private keys in files with PKCS#8 encoded format.
- JDK allows you to store public keys in files with X.509 encoded format.
Sample programs listed in this chapter have been tested with JDK 1.3 to 1.8.
Question: Key pairs are used to encrypt and decrypt data.
But how to encrypt and decrypt data? Which classes and methods to use?
