Method Detail

extractParameters

public static ASN1Encodable extractParameters(java.security.AlgorithmParameters params)
                                       throws java.io.IOException

Deprecated. use AlgorithmParametersUtils.extractParameters(AlgorithmParameters params)

Extract an ASN.1 encodable from an AlgorithmParameters object.

Parameters:

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

Returns:

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

Throws:

java.io.IOException - if an encoding cannot be extracted.

loadParameters

public static void loadParameters(java.security.AlgorithmParameters params,
                                  ASN1Encodable sParams)
                           throws java.io.IOException

Deprecated. use AlgorithmParametersUtils.loadParameters(AlgorithmParameters params, ASN1Encodable sParams)

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

Parameters:

params - the AlgorithmParameters object to be initialised.

sParams - the ASN.1 encodable to initialise params with.

Throws:

java.io.IOException - if the parameters cannot be initialised.

getDigestAlgName

public static java.lang.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 - the OID of the digest algorithm of interest.

Returns:

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