[PATCH v2 0/3] imap-send: modernize the OpenSSL API

OpenSSL recently released version 4.0.0-alpha1 [1]. Compiling with this version revealed some erroneous and deprecated code.

This series aims to update this code to use the documented OpenSSL APIs. All of the newly used APIs have existed since OpenSSL 1.1.0, the latest version of which was released in September 2019 [2]. IMHO there is no need to support even older OpenSSL versions.

Cc-ing Oswald as the original author of the affected code.

Beat Bolli (3):
  imap-send: use the OpenSSL API to access the subject alternative names
  imap-send: use the OpenSSL API to access the subject common name
  imap-send: move common code into function host_matches()
