annotate fuzz/fuzz-wrapfd.c @ 1928:333688ec53d0

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Handle ecdsa-sk flags, reject no-touch For the time being Dropbear will only allow SK auth with default parameters, user-presence needs to be set. In future handling of authorized_keys option "no-touch-required" can be added. This code would also be refactored to share between ecdsa and ed25519 once I get hardware/emulation to test ed25519.
