The following versions of Crypto++ have been validated by NIST and CSE for FIPS 140-2 level 1 conformance. Because only compiled executable code can receive FIPS validation, these versions are listed separately from the other source-code-only downloads. These download packages include the validated binary object, header files, API reference, and FIPS related documentation. Source code is also included for debugging purposes. (You cannot compile Crypto++ yourself and claim FIPS 140-2 conformance on the resulting module, unless the it goes through the validation process again.)
Because these packages contain compiled executable code, they have been signed with a PGP public key which is included inside the package. You can verify the PGP key's fingerprint by following the certificate link and obtaining a copy of the Crypto++ Library Security Policy from NIST's web site. The fingerprint is given in the Security Policy.
There are two mailing lists for Crypto++. The first is firstname.lastname@example.org, and the second is email@example.com.
As a courtesy, please join the discussion list with your real name instead of an online handle. Alternate webviews are for the lists are available at Crypto++ Announce - Google Groups and Crypto++ Users - Google Groups.
When posting a question to the Crypto++ user mailing list, please provide the following information, if applicable:
If you think you have found a bug in the library, then you should discuss it on the Users mailing list. Discussing it will help bring the issue to the attention of folks who can help resolve the issue. If you want to contribute a bug fix to the library, then include a DIFF or patch if its relatively small. Also see Bug Reports on the wiki.
If you want to contribute a new feature to the library, then please post a DIFF or patch to the mailing list if its relatively small. Though a feature may not be accepted into the library proper, it still may be useful to the community at large. Third party contributions that extend library functionality are available throughout the wiki and tagged with Category:Patch. Please note there are copyright, licensing and testing requirements for the patch to ensure ease of uptake by the Crypto++ library and library users. Also see Category:Patch on the wiki.
If you are interested in paid support for Crypto++ or consulting on a Crypto++ related project, then please see this list of companies and individuals providing services on the wiki. This listing is a free service for the Crypto++ community, and anyone may sign up to be listed by creating an account on the wiki.
