interimap/tests/tls/t, branch debian/latest

Port tests and documentation to Dovecot 2.4.

2025-04-26T16:03:03+00:00

See https://doc.dovecot.org/main/installation/upgrade/2.3-to-2.4.html .

tests/*/t: Explicitly pass `-in /dev/stdin` to openssl(1).

2024-03-06T14:09:05+00:00

tests/*/t: Replace filetype=sh with filetype=bash.

test suite: supply our own OpenSSL configuration file with MinProtocol=None.

So we can test TLSv1 as well, not just TLSv1.2 and later.

Also, explicitly set ssl_min_protocol=TLSv1 in the Dovecot configuration
file (the default as of 2.3.11.3), hence running TLS tests now require
Dovecot 2.3 or later.

libinterimap: remove default SSL_protocols value.

Namely, use the system default instead of "!SSLv2 !SSLv3 !TLSv1 !TLSv1.1".

As of Debian Buster (OpenSSL 1.1.1) this does not make a difference,
however using the system default provides better compatibility with
future libssl versions.

test suite: use a RSA certificate rather than ECDSA.

2020-12-09T13:57:11+00:00

It's arguably the most common use-case.  Generated with

  $ openssl genpkey -algorithm RSA -out tests/snippets/dovecot/dovecot.rsa.key
  $ openssl req -x509 -days 3650 -subj "/CN=InterIMAP test suite" \
        -key tests/snippets/dovecot/dovecot.rsa.key \
        -out tests/snippets/dovecot/dovecot.rsa.crt

Test suite: add new tests for SSL/TLS.

SSL connections are accepted on TCP port 10993.  Also, fix STARTTLS
directive, broken since fba1c36…
