Cryptrec sha1

WebSHA-1: A 160-bit hash function which resembles the earlier MD5 algorithm. This was designed by the National Security Agency (NSA) to be part of the Digital Signature Algorithm. Cryptographic weaknesses were discovered in SHA-1, and the standard was no longer approved for most cryptographic uses after 2010. Web: This Standard specifies secure hash algorithms - SHA-1, SHA-224, SHA-256, SHA-384, SHA-512, SHA-512/224 and SHA-512/256 - for computing a condensed representation of electronic data (message).

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.
