    Develop an activex control that can be used in scripts for perform signing, encryption, decryption and verification tasks, using digital certificates. The API of the control will be specified by us. The activex control should be usable on IE versions 8 and above on both 32 bit and 64 bit windows. The signatures and encryption output should be standards compliant and encoded correctly. The signatures and encryption should be verifiable using our server side component (which will be shared). Persons ...

    I need a C++ program that creates private keys in a specific order, finds the associated public key, and then outputs these two values into a tab-delimited list. The program should take advantage of CUDA, as well as multiple processors. It should also be able to be started and stopped at specific times, such that the same private key is never used twice, even across multiple platforms.

    We have some code built for Mac OS X that leverages the Mac Keychain for key management, signing and encoding/decoding data in the Cryptographic Message Syntax format. We are porting the code to POSIX and Win32, so the Keychain code has got to go. The job is to replace the functionality leveraging OpenSSL but keeping local storage secure. The Mac code is less than 200 lines. By the way we have a really cool little project, and more work ...
