Junio C Hamano	d7c67668fe	gpg-interface: move parse_signature() to where it should be Our signed-tag objects set the standard format used by Git to store GPG-signed payload (i.e. the payload followed by its detached signature) [1], and it made sense to have a helper to find the boundary between the payload and its signature in tag.c back then. Newer code added later to parse other kinds of objects that learned to use the same format to store GPG-signed payload (e.g. signed commits), however, kept using the helper from the same location. Move it to gpg-interface; the helper is no longer about signed tag, but it is how our code and data interact with GPG.

Junio C Hamano	a50e7ca321	gpg-interface: move parse_gpg_output() to where it should be Earlier, `ffb6d7d5` (Move commit GPG signature verification to commit.c, 2013-03-31) moved this helper that used to be in pretty.c (i.e. the output code path) to commit.c for better reusability. It was a good first step in the right direction, but still suffers from a myopic view that commits will be the only thing we would ever want to sign---we would actually want to be able to reuse it even wider. The function interprets what GPG said; gpg-interface is obviously a better place. Move it there. Signed-off-by: Junio C Hamano <gitster@pobox.com>	10 years ago
Michael J Gruber	71c214c840	gpg-interface: provide access to the payload In contrast to tag signatures, commit signatures are put into the header, that is between the other header parts and commit messages. Provide access to the commit content sans the signature, which is the payload that is actually signed. Commit signature verification does the parsing anyways, and callers may wish to act on or display the commit object sans the signature.

Michael J Gruber	01e57b5d91	gpg-interface: provide clear helper for struct signature_check The struct has been growing members whose malloced memory needs to be freed. Do this with one helper function so that no malloced memory shall be left unfreed.

Junio C Hamano	2f47eae2a1	Split GPG interface into its own helper library This mostly moves existing code from builtin/tag.c (for signing) and builtin/verify-tag.c (for verifying) to a new gpg-interface.c file to provide a more generic library interface. - sign_buffer() takes a payload strbuf, a signature strbuf, and a signing key, runs "gpg" to produce a detached signature for the payload, and appends it to the signature strbuf. The contents of a signed tag that concatenates the payload and the detached signature can be produced by giving the same strbuf as payload and signature strbuf. - verify_signed_buffer() takes a payload and a detached signature as <ptr, len> pairs, and runs "gpg --verify" to see if the payload matches the signature. It can optionally capture the output from GPG to allow the callers to pretty-print it in a way more suitable for their contexts. "verify-tag" (aka "tag -v") used to save the whole tag contents as if it is a detached signature, and fed gpg the payload part of the tag. It relied on gpg to fail when the given tag is not signed but just is annotated. The updated run_gpg_verify() function detects the lack of detached signature in the input, and errors out without bothering "gpg". Signed-off-by: Junio C Hamano <gitster@pobox.com>	13 years ago
