Does anyone have suggestions that can do #cryptographic signature verification of streaming data (as in a pipe)? The problem with #gpg in this case is that it will emit all the data out the pipe, only indicating with an exit code if the signature was good - at which point most of the data may have been processed. #SequoiaPGP is slightly better, withholding the last 25MB until things are fully verified.

I suspect I need something that signs blocks of the input. Does it exist? #askFedi
