WebRSA is an encryption algorithm, used to securely transmit messages over the internet. It is based on the principle that it is easy to multiply large numbers, but factoring large numbers is very difficult. For example, it is easy to check that 31 and 37 multiply to 1147, but trying to find the factors of 1147 is a much longer process. RSA is an example of public-key … WebMay 1, 2024 · First, you use the decryption operation on the plaintext. For example, s = SIGNATURE (p) = p ^ d % z. Then, the recipient can verify the digital signature by applying the encryption function and comparing the result with the message. For example, m = …
