Previously, gpg2 2.0 would be rejected, but the same version installed
as "gpg" would be accepted.
* lisp/epg-config.el (epg-gpg2-minimum-version): New constant.
(epg-config--program-alist) <OpenPGP>: Require a version in 1.4.3..2.0
or 2.1.6+., not just anything above 1.4.3.
(epg-check-configuration): Accept a list of required version
intervals, in addtion to just a single minimum.
This is needed to avoid losing user settings made under the obsolete
name (Bug#31603).
* lisp/epa.el (epa-pinentry-mode): Move obsolete varalias from here...
* lisp/epg-config.el (epg-pinentry-mode): ...to here.
* lisp/epa.el (epa-pinentry-mode): Make into obsolete alias for...
* lisp/epg-config.el (epg-pinentry-mode): ...this new user option.
* lisp/epg.el (epg-context): Use it as the default value for
pinentry-mode.
* etc/NEWS: Announce name change.
* lisp/epa-file.el (epa-file-insert-file-contents)
(epa-file-write-region):
* lisp/epa.el (epa-decrypt-file, epa-sign-file)
(epa-encrypt-file, epa-decrypt-region)
(epa-sign-region, epa-encrypt-region): Don't change
epg-context-pinentry-mode from the default.
* lisp/epa.el (epa--select-safe-coding-system): Remove,
`select-safe-coding-system' has been present since Emacs 20.3.
(epa--encode-coding-string, epa--decode-coding-string):
* lisp/epg.el (epg--decode-coding-string, epg--encode-coding-string)
(epg--clear-string): Remove, the corresponding Emacs functions are so
old they don't show up in NEWS. Furthermore, the fallback for
the *-coding-string functions was `identity' which wouldn't have
worked anyway, since it only takes a single argument.
(epg--make-temp-file): Remove, `make-temp-file' has been present since
Emacs 21.1.
* lisp/epg-config.el (epg-gpg-program, epg-gpgsm-program)
(epg-gpgconf-program, epg-gpg-home-directory)
(epg-passphrase-coding-system, epg-debug): Remove unneeded :group
parameter.
Most of this change is to boilerplate commentary such as license URLs.
This change was prompted by ftp://ftp.gnu.org's going-away party,
planned for November. Change these FTP URLs to https://ftp.gnu.org
instead. Make similar changes for URLs to other organizations moving
away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and
fsf.org when this works, as this will further help defend against
man-in-the-middle attacks (for this part I omitted the MS-DOS and
MS-Windows sources and the test tarballs to keep the workload down).
HTTPS is not fully working to lists.gnu.org so I left those URLs alone
for now.
Fixes bug#23561.
* test/automated/epg-tests.el
(epg-tests-program-alist-for-passphrase-callback): New
constant.
(epg-tests-find-usable-gpg-configuration): New function,
renamed from `epg-tests-gpg-usable'. All callers changed.
(epg-tests-gpg-usable): Remove.
* lisp/epg-config.el (epg-config--program-alist): Factor out
constructor element to...
(epg-config--configuration-constructor-alist): ...here.
(epg-find-configuration): Rename FORCE argument to NO-CACHE,
and add PROGRAM-ALIST argument.

We changed the default gpg program to "gpg2" from "gpg" in the commit
f93d669a16. However, there are two
maintained branches (2.0 and 2.1) and Emacs doesn't work well with 2.0
series. Check the actual version of "gpg2" at run time, and properly
divert to "gpg" if necessary.
* lisp/epg-config.el: Require 'cl-lib for `cl-destructuring-bind'.
(epg-config--program-alist): New variable.

(epg-config--make-gpg-configuration): New function.
(epg-config--make-gpgsm-configuration): New function.

* epg-config.el (epg-gpgconf-program): New variable.
* epg.el (epg--start): Call `pinentry-start' if
allow-emacs-pinentry is set in ~/.gnupg/gpg-agent.conf.
