Class PKCS5S2ParametersGenerator
public class 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
PKCS5S2ParametersGenerator
public PKCS5S2ParametersGenerator()
construct a PKCS5 Scheme 2 Parameters generator.
generateDerivedMacParameters
public CipherParameters generateDerivedMacParameters(int keySize)
Generate a key parameter for use with a MAC derived from the password,
salt, and iteration count we are currently initialised with.
- generateDerivedMacParameters in interface PBEParametersGenerator
keySize
- the size of the key we want (in bits)
- a KeyParameter object.
generateDerivedParameters
public CipherParameters generateDerivedParameters(int keySize)
Generate a key parameter derived from the password, salt, and iteration
count we are currently initialised with.
- generateDerivedParameters in interface PBEParametersGenerator
keySize
- the size of the key we want (in bits)
- a KeyParameter object.
generateDerivedParameters
public CipherParameters generateDerivedParameters(int keySize,
int ivSize)
Generate a key with initialisation vector parameter derived from
the password, salt, and iteration count we are currently initialised
with.
- generateDerivedParameters in interface PBEParametersGenerator
keySize
- the size of the key we want (in bits)ivSize
- the size of the iv we want (in bits)
- a ParametersWithIV object.
