Crypt rsa
WebFor the RSA signatures, the most adopted standard is "PKCS#1", which has several versions (1.5, 2.0, 2.1, 2.2), the latest described in RFC 8017. The PKCS#1 standard defines the RSA signing algorithm (RSASP1) and the RSA signature verification algorithm (RSAVP1), which are almost the same like the implemented in the previous section. WebThe SHA hash functions were designed by the National Security Agency (NSA). SHA-1 is the most established of the existing SHA hash functions, and it's used in a variety of security applications and protocols.
