Web我们用标准库 crypto/rsa 来生成秘钥,用 crypto/rand 库来生成随机数。 // The GenerateKey method takes in a reader that returns random bits, and // the number of bits privateKey, err := rsa.GenerateKey(rand.Reader, 2048) if err != nil { panic(err) } // The public key is a part of the *rsa.PrivateKey struct publicKey ... 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…
