Class PKCS5S1ParametersGenerator
public class PKCS5S1ParametersGenerator
Generator for PBE derived keys and ivs as defined by PKCS 5 V2.0 Scheme 1.
Note this generator is limited to the size of the hash produced by the
digest used to drive it.
The document this implementation is based on can be found at
RSA's PKCS5 Page
PKCS5S1ParametersGenerator
public PKCS5S1ParametersGenerator(Digest digest)
Construct a PKCS 5 Scheme 1 Parameters generator.
digest
- the digest to be used as the source of derived keys.
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.
