How to cancel post on newsgroup with cancel lock? (Sha)
RE: [NNTP]Cancel post with sha - rlebeau - 01-03-2020
You would simply post a new NNTP message to the server, containing a "Cancel-Key" header that matches a previous message's "Cancel-Lock" header.
See https://www.eyrie.org/~eagle/usefor/drafts/draft-ietf-usefor-cancel-lock-01.txt for more details.
How you calculate the values of those headers is outside the scope of Indy. Though Indy does have SHA1 and HMAC classes available.
