Is there any available free & open source implementation of RSA-2048 for SQL Server 2000?

I'm trying to do some cryptography for SQL Server 2000, and I know that only SQL 2005+ comes with built-in functionality for do开发者_如何学编程ing this natively.

Do you know any open source implementation that I can use for free of RSA-2048 cryptography?

I believe you need Extended Stored Procedures to do this. You can make them yourself building on one of the many C or C++ open-source implementations or the Windows CryptoAPI.

Alternatively a quick Google search reveals XP_CRYPT which is an implementation of this (but it is not free if you want RSA with any secure keylength).

Check open source libraries under Elliptic curve cryptography Which should you should be able to use following developer guide
