Rsa

DevSolutionsCrypt library is a powerful and easy to use cryptographic ActiveX and DLL component for Windows developers that allows applications to encrypt/decrypt data or files using the latest industry standard strong encryption algorithms.

axsStrongBox is a COM component which provides secure data encryption (public and private key) using industry standard, strong algorithms. It also provides digital signatures, hashing, GZIP and Base64 capability.

SignetSure is Win32 security tool for protecting files from hacker alteration. Create digital signatures for your files from Win32 app. Then authenticate your files with single API call. Uses RSA public key cryptography. C/C++ or Visual Basic.

PELock - is an application that allows you to protect Windows executable files (so called exe-protector). Besides that, PELock allows easy creation of application of evaluation-demo type, which use license key system.

SafeHouse provides transparent on-the-fly hard drive encryption for your PC. Using SafeHouse, you can allocate portions of your existing hard drives to be reserved for encrypted data. SafeHouse appears to Windows as another drive letter.
