org.bouncycastle.crypto.generators.BaseKDFBytesGenerator
- DerivationFunction
public class BaseKDFBytesGenerator
extends java.lang.Object
Basic KDF generator for derived keys and ivs as defined by IEEE P1363a/ISO 18033
This implementation is based on ISO 18033/P1363a.
BaseKDFBytesGenerator
protected BaseKDFBytesGenerator(int counterStart,
Digest digest)
Construct a KDF Parameters generator.
counterStart
- value of counter.digest
- the digest to be used as the source of derived keys.
generateBytes
public int generateBytes(byte[] out,
int outOff,
int len)
throws DataLengthException,
IllegalArgumentException
fill len bytes of the output buffer with bytes generated from
the derivation function.
