public static ASN1Encodable extractParameters(AlgorithmParameters params) throws IOException

Extract an ASN.1 encodable from an AlgorithmParameters object.

Parameters
params:AlgorithmParameters

the object to get the encoding used to create the return value.

Returns:ASN1Encodable

an ASN.1 object representing the primitives making up the params parameter.

Exceptions
IOException:
if an encoding cannot be extracted.

public static void loadParameters(AlgorithmParameters params, ASN1Encodable sParams) throws IOException

Load an AlgorithmParameters object with the passed in ASN.1 encodable - if possible.

Parameters
params:AlgorithmParameters

the AlgorithmParameters object to be initialised.

sParams:ASN1Encodable

the ASN.1 encodable to initialise params with.

Exceptions
IOException:
if the parameters cannot be initialised.
