Log Message:
New Channels package with nio based channels for various crypto related tasks such as digests, signing, verifying and encoding.
DigestsChannel, SigningChannel and VerifyingChannel are complete, but not tested.
AbstractEncodingChannel will be used for a Base64/Base32 Channel as well as possibly an xml canonicalization channel in the xmlsig library.
