MobaXterm OpenSSL

Since more recent MobaXterm versions a little more recent version of OpenSSL is included. Currently with MobaXterm 23.4 OpenSSL 1.1.1v 1 Aug 2023 is included.

Starting with openssl 3.0.11 and 3.1.3 the plugins are not based on MobaXterm Plugins anymore.
There are different versions available. From mentioned versions (September 2023) on, just decide and use one version. 1.1.1 is out of support.

OpenSSL 3.3.0 is the latest version (April 2024). The extension only contains the openssl binary and the libraries. Do not combine with other version 3 extensions.
Download: openssl_3.3.0.mxt3 from 2024-April-09

OpenSSL 3.2.1 is the latest version (January 2024). The extension only contains the openssl binary and the libraries. Do not combine with other version 3 extensions.
Download: openssl_3.2.1.mxt3 from 2024-January-30

OpenSSL 3.1.5 is the latest release (January 2024). This only contains the library files and the openssl binary.
Download: openssl_3.1.5.mxt3 from 2024-January-30

OpenSSL 3.0.13 is the latest release (January 2024). This only contains the library files and the openssl binary.
Download: openssl_3.0.13.mxt3 from 2024-January-30

OpenSSL 1.1.1w is the last supported version 1.1.1 (September 2023). It’s end of life. The files is based on MobaXterm Plugin and has just replaced the library and biniary files. All the config examples, additional scripts, directory structure are kept in place. Makes problems since some MobaXterm Update. Use OpenSSL3.0.x or 3.1.x instead
Download: openssl_1.1.1w.mxt3 from 2023-September-11

OpenSSL 1.0.2_legacy is an old version and contains 1.0.2g and 1.0.2u. It’s just for testing SSLv2 and SSLv3 connections… You really should not need that anymore!Download: openssl_1.0.2_legacy.mxt3

Installation
Just put the extensions in place in the same path as your MobaXterm binary.
When you have configured a static root directory, you should delete that before installing a new version of the Plugin.
How is OpenSSL compiled?
You need to fetch a current perl and binutils in MobaXterm.
See also mobaxterm und openssl3 alpha 8 (German) and OpenSSL3 in MobaXterm (German).
Afterwards, this will be sufficient:

tar -xzf openssl...tgz
cd openssl...
./config
make

Why would I need a newer library and binary of openssl?
Older versions are simply unsupported.
OpenSSL 1.1.1 uses SNI as default. So it makes testing easier.
OpenSSL 1.1.1 supports TLS 1.3
OpenSSL 1.1.1 added support for LDAP via StartTLS.
OpenSSL 3 has the same features. You can test, if you’ll get into any troubles, when OpenSSL switches to version 3.
Can I get older/newer versions?
I’ll create new versions, depending on my time and needs.
Can I get help?
Basically no. But you may leave a comment here or reach out via mail to me.
