<div class="class-description">Implementation of the One-Pass Signature Packets (Tag 4)
|
|
|
|
RFC4880 5.4:
|
|
The One-Pass Signature packet precedes the signed data and contains
|
|
enough information to allow the receiver to begin calculating any
|
|
hashes needed to verify the signature. It allows the Signature
|
|
packet to be placed at the end of the message, so that the signer
|
|
can compute the entire signed message in one pass.</div>
