pub fn parse_signed_buffer(buf: &[u8]) -> Option<(Vec<u8>, Vec<u8>)>Expand description
Split a signed buffer (e.g. a tag object) into (payload, signature).
Port of Git’s gpg-interface.c:parse_signed_buffer/parse_signature: scans
the buffer line by line and records the offset of the last line that begins
a recognized signature armor (GpgFormat::from_signature). The payload is
everything before that offset and the signature is everything from it to the
end. Unlike commits, a signed tag appends the armored signature directly
after the tag body with no gpgsig header and no per-line indentation.
Returns None when no armor line is found (the buffer is unsigned).
