public PSSParameterSpec(String mdName, String mgfName, AlgorithmParameterSpec mgfSpec, int saltLen, int trailerField)
PSSParameterSpec
as defined in
the PKCS #1 standard using the specified message digest,
mask generation function, parameters for mask generation
function, salt length, and trailer field values.
mdName
- the algorithm name of the hash function.mgfName
- the algorithm name of the mask generation
function.mgfSpec
- the parameters for the mask generation
function. If null is specified, null will be returned by
getMGFParameters().saltLen
- the length of salt.trailerField
- the value of the trailer field.
NullPointerException
- if mdName
,
or mgfName
is null.
IllegalArgumentException
- if saltLen
or trailerField
is less than 0.public PSSParameterSpec(int saltLen)
PSSParameterSpec
using the specified salt length and other default values as
defined in PKCS#1.
saltLen
- the length of salt in bits to be used in PKCS#1
PSS encoding.
IllegalArgumentException
- if saltLen
is
less than 0.Method Detail |
