WebJan 7, 2024 · In this article. Providers associated with Cryptography API ( CryptoAPI) are called cryptographic service providers (CSPs) in this documentation. CSPs typically implement cryptographic algorithms and provide key storage. Providers associated with CNG, on the other hand, separate algorithm implementation from key storage. WebRSA is the most widespread and used public key algorithm. Its security is based on the difficulty of factoring large integers. The algorithm has withstood attacks for more than 30 years, and it is therefore considered reasonably secure for new designs.
