Hi,

Constructor for PGPSignatureGenerator gives following exception only for
following HashAlgorithmTags:---

org.bouncycastle.openpgp.PGPException: unknown hash algorithm tag in
getDigestName

PGPSignatureGenerator sGen = new
PGPSignatureGenerator(pgpSec.getKeyEncryptionAlgorithm(),HashAlgorithmTags.DOUBLE_SHA,
"BC");
PGPSignatureGenerator sGen = new
PGPSignatureGenerator(pgpSec.getKeyEncryptionAlgorithm(),HashAlgorithmTags.HAVAL_5_160,
"BC");
PGPSignatureGenerator sGen = new
PGPSignatureGenerator(pgpSec.getKeyEncryptionAlgorithm(),HashAlgorithmTags.TIGER_192,
"BC");


For other HashAlgorithmTags, it works correctly.
Is this a bug which is not yet removed? Are these algorithms not supported?
