BcPBESecretKeyEncryptorBuilder

public BcPBESecretKeyEncryptorBuilder(int encAlgorithm,
                                      int s2kCount)

Create an SecretKeyEncryptorBuilder with the S2K count different to the default of 0x60.

Parameters:

encAlgorithm - encryption algorithm to use.

s2kCount - iteration count to use for S2K function.

public BcPBESecretKeyEncryptorBuilder(int encAlgorithm,
                                      PGPDigestCalculator s2kDigestCalculator)

Create a builder which will make encryptors using the passed in digest calculator. If a MD5 calculator is passed in the builder will assume the encryptors are for use with version 3 keys.

Parameters:

encAlgorithm - encryption algorithm to use.

s2kDigestCalculator - digest calculator to use.
