From 57699b1fa6367a42d5877afcfdb1504e52835ed9 Mon Sep 17 00:00:00 2001 From: Tim Culverhouse Date: Mon, 25 Apr 2022 08:30:44 -0500 Subject: feat: add gpg integration This commit adds gpg system integration. This is done through two new packages: gpgbin, which handles the system calls and parsing; and gpg which is mostly a copy of emersion/go-pgpmail with modifications to interface with package gpgbin. gpg includes tests for many cases, and by it's nature also tests package gpgbin. I separated these in case an external dependency is ever used for the gpg sys-calls/parsing (IE we mirror how go-pgpmail+openpgp currently are dependencies) Two new config options are introduced: * pgp-provider. If it is not explicitly set to "gpg", aerc will default to it's internal pgp provider * pgp-key-id: (Optionally) specify a key by short or long keyId Signed-off-by: Tim Culverhouse Acked-by: Koni Marti Acked-by: Robin Jarry --- lib/crypto/gpg/gpgbin/encrypt.go | 35 +++++++++++++++++++++++++++++++++++ 1 file changed, 35 insertions(+) create mode 100644 lib/crypto/gpg/gpgbin/encrypt.go (limited to 'lib/crypto/gpg/gpgbin/encrypt.go') diff --git a/lib/crypto/gpg/gpgbin/encrypt.go b/lib/crypto/gpg/gpgbin/encrypt.go new file mode 100644 index 00000000..4cbac37b --- /dev/null +++ b/lib/crypto/gpg/gpgbin/encrypt.go @@ -0,0 +1,35 @@ +package gpgbin + +import ( + "bytes" + "io" + + "git.sr.ht/~rjarry/aerc/models" +) + +// Encrypt runs gpg --encrypt [--sign] -r [recipient].
