WebOct 11, 2024 · RSA is the signing (not encrypting, despite what the text says) algorithm, and it operates on a hash of the content to be signed. SHA1 is the hashing algorithm (it produces a short, one-way non-reversible version of the full certificate) that is used to produce the string which RSA then signs.
