The general idea is that URL (and other elisp packages, such as Gnus,
W3 and maybe others) need SSL/TLS functionality in order to connect to
HTTP or IMAP servers (for browing the web, or reading mail) that uses
SSL/TLS. OpenSSL or GNUTLS provides that, via a command line
interface (I wrote patches to make an elisp API for them, via the
shared libraries, but they were never adopted). Since having each and
every elisp application write its own OpenSSL/GNUTLS handling, ssl.el
was presumably written, mimicking the open-network-stream API, only
that it open the stream over a SSL/TLS connection via the command line
application. The point of SSL/TLS is to provide authentication,
integrity and/or encryption (all optional, and can be configured in
very high detail, although this configuration is probably not possible
via a command line application, but would have been one of the
features of my direct elisp API to the libraries). The default
behaviour of both OpenSSL and GNUTLS is to negotiate the most secure,
mutually implemented, algorithms, though.
I wrote tls.el that uses GNUTLS, instead of OpenSSL which ssl.el uses.
Gnus and smtpmail.el uses tls.el, and if possible I think url-https.el
should as well. I'm not sure we need ssl.el in Emacs, it might be
better to make users use GNUTLS instead of OpenSSL.
