Constructor Detail

PssParameters

public PssParameters()

Construct default RSASSA-PSS parameters according to PKCS #1 definition of default value.

PssParameters

public PssParameters(String hashAlgorithm)

Construct RSASSA-PSS parameters using default trailer and the same digest algorithm for both hash and mgf1.

Parameters:

hashAlgorithm - digest algorithm to use for hash and mgf1.

PssParameters

public PssParameters(String hashAlgorithm,
             int saltLength)

Construct RSASSA-PSS parameters using default trailer and the same digest algorithm for both hash and mgf1.

Parameters:

hashAlgorithm - digest algorithm to use for hash and mgf1.

saltLength - size of salt in bytes.

PssParameters

public PssParameters(String hashAlgorithm,
             String maskGenAlgorithm,
             int saltLength)

Construct RSASSA-PSS parameters using custom parameters.

Parameters:

hashAlgorithm - digest algorithm to use for hash.

maskGenAlgorithm - digest algorithm to use for mgf1.

saltLength - size of salt in bytes, -1 means use the digest size.
