* go: removed io/ioutilMoritz Poldrack2022-08-221-2/+1
| | | | | | | | | | Since the minimum required version of Go has been bumped to 1.16, the deprecation of io/ioutil can now be acted upon. This Commit removes the remaining dependencies on ioutil and replaces them with their io or os counterparts. Signed-off-by: Moritz Poldrack <git@moritz.sh> Acked-by: Robin Jarry <robin@jarry.cc>
* lint: work nicely with wrapped errors (errorlint)Moritz Poldrack2022-08-041-4/+4
| | | | | | | | Error wrapping as introduced in Go 1.13 adds some additional logic to use for comparing errors and adding information to it. Signed-off-by: Moritz Poldrack <moritz@poldrack.dev> Acked-by: Robin Jarry <robin@jarry.cc>

* logging: use level-based logger functionsRobin Jarry2022-07-231-7/+4
| | | | | | | | | | | | Do not pass logger objects around anymore. Shuffle some messages to make them consistent with the new logging API. Avoid using %v when a more specific verb exists for the argument types. The loggers are completely disabled (i.e. Sprintf is not even called) by default. They are only enabled when redirecting stdout to a file. Signed-off-by: Robin Jarry <robin@jarry.cc> Acked-by: Moritz Poldrack <moritz@poldrack.dev>
* pgp: add attach key commandTim Culverhouse2022-05-061-0/+34
| | | | | | | | | Add compose command ("attach-key") to attach the public key associated with the sending account. Public key is attached in ascii armor format, with the mimetype set according to RFC 3156 ("application/pgp-keys").

* pgp: check encryption keys before sending messageTim Culverhouse2022-05-061-0/+8
| | | | | | | | | | | | | | | | Add check for public keys of all message recipients (to, cc, and bcc) before sending the message. Adds an OnFocusLost callback to header editors to facilitate a callback for checking keys whenever a new recipient is added (OnChange results in too many keyring checks). Once encryption is initially set, the callbacks are registered. If a public key is not available for any recipient, encryption is turned off. However, notably, the callbacks are still registered meaning as s soon as the user removes the recipients with missing keys, encryption is turned back on.

* pgp: check for signing key before signing timeTim Culverhouse2022-05-041-0/+18
| | | | | | | | | | Check that the signing key exists when the user issues the :sign command. The signing key ID will be displayed in the security status also, allowing the user to see what key will be used to sign the message.

* feat: add gpg integrationTim Culverhouse2022-04-271-21/+40
| | | | | | | | | | | | | | | | | | | 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 <tim@timculverhouse.com> Acked-by: Koni Marti <koni.marti@gmail.com> Acked-by: Robin Jarry <robin@jarry.cc>
