Method Detail

extractParametersback to summary
public static ASN1Encodable extractParameters(AlgorithmParameters params) throws IOException

Deprecated

use AlgorithmParametersUtils.extractParameters(AlgorithmParameters params)

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.
getDigestAlgNameback to summary
public static String getDigestAlgName(ASN1ObjectIdentifier digestAlgOID)

Deprecated

use MessageDigestUtils,getDigestName()

Attempt to find a standard JCA name for the digest represented by the past in OID.

Parameters
digestAlgOID:ASN1ObjectIdentifier

the OID of the digest algorithm of interest.

Returns:String

a string representing the standard name - the OID as a string if none available.

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

Deprecated

use AlgorithmParametersUtils.loadParameters(AlgorithmParameters params, ASN1Encodable sParams)

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.
