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
Conclusion:
Sample programs listed in this chapter have been tested with JDK 12.
Question: Key pairs are used to encrypt and decrypt data. But how to encrypt and decrypt data? Which classes and methods to use?
