It is strongly recommended that you always use the latest release of Cryptlib, which will include enhancements and improvements over the previously available versions. A 420+page user's guide and manual is also available above which is distributed separately from the code.
Cryptlib is distributed in Zip format which can be extracted on all target operating systems. Before working with it, you should read the Installation section of the manual which covers details on installing the software on different platforms (under Windows you need to set up a Cryptlib network share, under Unix you need to unzip with the -a option).
There is a Cryptlib ActiveX control available which can be used with Visual Basic and other languages. This location also contains the Cryptlib user interface components, which provide a key/certificate generation wizard and certificate viewer.
There is a very low volume mailing list available which covers Cryptlib development and usage and implementation details. To subscribe, send mail to the list administrator with the words "subscribe Cryptlib" in the message body. You should receive a reply informing you that you've been added to the list.
Cryptlib 3.1 (and by extension all earlier versions) has been end-of-life'd.
Anyone who has a support contract for Cryptlib 3.1 will continue to receive support until the contract is up for renewal, after which you must upgrade to the current release. Anyone without a support contract will no longer be able to receive support for 3.1 or earlier versions.
