Secret Key Generation and Management

This chapter provides tutorial notes and example codes on secret keys. Topics include secret keys for Blowfish, DES, or HmacMD5 encryption algorithms; key generator class; test program to generate secret keys and save them in files.

javax.crypto.SecretKey - The Secret Key Interface

javax.crypto.KeyGenerator - Generating Secret Keys

Converting Secret Keys to and from Byte Arrays

JceSecretKeyTest.java - Secret Key Test Program

Conclusions:

Sample programs listed in this chapter have been tested with JDK 1.3 to 1.8.
