Method Detail

computeDigest

public byte[] computeDigest(net.jsign.DigestAlgorithm digestAlgorithm)
                     throws IOException

Description copied from interface: Signable

Computes the digest of the file.

Specified by:

computeDigest in interface Signable

Parameters:

digestAlgorithm - the digest algorithm to use

Returns:

the digest of the file

Throws:

IOException - if an I/O error occurs

createIndirectData

public org.bouncycastle.asn1.ASN1Object createIndirectData(net.jsign.DigestAlgorithm digestAlgorithm)
                                                    throws IOException

Description copied from interface: Signable
