java.lang.Objectorg.bouncycastle.crypto.PBEParametersGenerator
org.bouncycastle.crypto.generators.PKCS5S2ParametersGenerator
Generator for PBE derived keys and ivs as defined by PKCS 5 V2.0 Scheme 2. This generator uses a SHA-1 HMac as the calculation function.
The document this implementation is based on can be found at RSA's PKCS5 Page
