The RSA algorithm involves four steps: key generation, key distribution, encryption, and decryption. A basic principle behind RSA is the observation that it is practical to find three very large positive integers e, d, and n, such that with modular exponentiation for all integers m (with 0 ≤ m < n): and that knowing e and n, or even m, it can be extremely difficult to find d. The triple bar (≡) here denotes modular congruence (which is to say that when you divide (m ) by n and m by n, they bot… 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.
