Method Details

find

org.bouncycastle.asn1.x509.AlgorithmIdentifier find(org.bouncycastle.asn1.x509.AlgorithmIdentifier sigAlgId)

Find the digest algorithm identifier that matches with the passed in signature algorithm identifier.

Parameters:

sigAlgId - the signature algorithm of interest.

Returns:

an algorithm identifier for the corresponding digest, null if the signature algorithm does not identify one.

find

org.bouncycastle.asn1.x509.AlgorithmIdentifier find(org.bouncycastle.asn1.ASN1ObjectIdentifier digestOid)

Find the algorithm identifier that matches with the passed in digest OID.

Parameters:

digestOid - the OID of the digest algorithm of interest.

Returns:

an algorithm identifier for the digest signature.

find

org.bouncycastle.asn1.x509.AlgorithmIdentifier find(String digAlgName)

Find the algorithm identifier that matches with the passed in digest name. The name may also be given in dotted OID form.

Specified by:

find in interface AlgorithmIdentifierFinder

Parameters:

digAlgName - the name of the digest algorithm of interest.

Returns:

an algorithm identifier for the digest signature.

Throws:

IllegalArgumentException - if the name is not recognised.
