public class OpenSSLPBEParametersGenerator extends PBEParametersGenerator
Originally this scheme was a simple extension of PKCS 5 V2.0 Scheme 1 using MD5 with an iteration count of 1. The default digest was changed to SHA-256 with OpenSSL 1.1.0. This implementation still defaults to MD5, but the digest can now be set.

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.
