mod_ssl

mod_ssl is an optional module for the Apache HTTP Server.

Provides strong cryptography for the Apache v1.3 and v2 webserver via the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) cryptographic protocols by the help of the Open Source SSL/TLS toolkit OpenSSL.

Version clarification

The mod_ssl in Apache 2 is based on the mod_ssl for Apache 1.3, but the two versions are not the same module. The mod_ssl available at www.modssl.org is only for Apache 1.3. The mod_ssl module is part of Apache 2 by default, you just turn it on with configure/compile options, while for Apache 1.3.x it is an addon package requiring a few other steps in the configure/compile process and additional packages to link with.

License

The mod_ssl package for Apache v1.3 is licensed under a BSD-style license, which basically means that you are free to get and use it for commercial and non-commercial purpose.

The mod_ssl module for Apache v2 is part of Apache v2, licensed with Apache License 2.0.

History

The mod_ssl v1 package was initially created in April 1998 by Ralf S. Engelschall via porting Ben Laurie's Apache-SSL 1.17 source patches for Apache 1.2.6 to Apache 1.3b6 . Because of conflicts with Ben Laurie's development cycle it then was re-assembled from scratch for Apache 1.3.0 by merging the old mod_ssl 1.x with the newer Apache-SSL 1.18. From this point on mod_ssl lived its own life as mod_ssl v2.

The first publically released version was mod_ssl 2.0.0 from August 10th, 1998.

After US export restrictions on cryptographic software were loosened, mod_ssl became part of the Apache HTTP Server with the release of Apache httpd 2 .
