Class OpenSSLPBEParametersGenerator
public class OpenSSLPBEParametersGenerator
Generator for PBE derived keys and ivs as usd by OpenSSL.
The scheme is a simple extension of PKCS 5 V2.0 Scheme 1 using MD5 with an
iteration count of 1.
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.
|
CipherParameters | generateDerivedParameters(int keySize) - Generate a key parameter derived from the password, salt, and iteration
count we are currently initialised with.
|
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.
|
void | init(byte[] password, byte[] salt) - Initialise - note the iteration count for this algorithm is fixed at 1.
