From 2f47eae2a1337bd0cb50dbc936df6433f460bb4a Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Wed, 7 Sep 2011 21:19:47 -0700 Subject: 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 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".
