SSL support for Lynx 2.8.5pre.1

-- adapted from http://www.mentovai.com/lynx/

Lynx, in its unmodified form, will not allow you to make secure socket layer

(SSL) connections.  SSL is used for the secure transfer of information over the

Internet.  Many sites are now requiring SSL to ensure security for themselves

and their users.  With a version of Lynx modified to support SSL, Lynx users

can now visit these sites with ease as well.

The SSL configure option (--with-ssl) for Lynx provides the ability to make use

of SSL over HTTP for secure access to web sites (HTTPS) and over NNTP for

secure access to news servers (SNEWS).  SSL is handled transparently, allowing

users to continue accessing web sites and news services from within Lynx

through the same interface for both secure and standard transfers.

This is based on, and requires, the OpenSSL library.  OpenSSL's distribution

and use may be restricted by licenses and laws.  For information on obtaining

OpenSSL, as well as information on its distribution, see

	http://www.openssl.org/

The main distribution site is at

	ftp://ftp.openssl.org/source/

Lynx also has experimental support for GnuTLS (configure option --with-gnutls).

For information on GnuTLS, see

	http://www.gnu.org/software/gnutls/

To test your version of Lynx for SSL support, try it out with an SSL site.

Below are secure (https) pages which will load if your browser contains SSL

support and you accept their certificates; they give you some information about

the connection.

	https://www2.ggn.net/cgi-bin/ssl

Lynx will complain about the certificate, since the certificate presented is

untrusted.  You may accept this certificate to test your configuration, since

it is a test, but it is a bad idea to blindly accept certificates from unknown

websites if you are transmitting form data or files.

You should review the document README.sslcerts for a detailed discussion of

correct certificate handling possibilities and procedures in lynx.

Users are reminded to check the laws and regulations about encryption software

in their own countries.

Lynx is GPL'd, for our own use it falls under the regulations in EAR section

        which is not subject an express agreement for the payment a

        licensing fee or royalty for commercial production or sale of

        any product developed with the source code, is released from

        EI controls and may be exported or reexported without review

        under License Exception TSU, provided you have submitted

        written notification to BXA of the Internet location (e.g.,

        URL or Internet address) or a copy of source code by the time

        of export.
