iterateFile :: FilePath -> Iteratee ASN1Event IO a -> IO (Either SomeException a)Source
iterate over a file using a file enumerator.
iterateByteString :: Monad m => ByteString -> Iteratee ASN1Event m a -> m (Either SomeException a)Source
iterate over a lazy bytestring using a list enumerator over the bytestring chunks.
enumReadBytes :: Monad m => Enumeratee ByteString ASN1Event m aSource
enumReadBytes parse bytestring and generate asn1event.
enumWriteBytes :: Monad m => Enumeratee ASN1Event ByteString m aSource
write Bytes of events enumeratee
toBytes :: [ASN1Event] -> ByteStringSource
serialize asn1 headers
putHeader :: ASN1Header -> ByteStringSource
putIdentifier encode an ASN1 Identifier into a marshalled value
