WebThese kinds of signatures take up 4s bits for a security of s bits. Example for RSA-PSS with message recovery: RSA modulus: 3072 bits hash: SHA-256 salt: 64 random bits Then, the signature of 3072 bits (384 bytes) stores a 256 bit hash (32 bytes), a 64 bit salt (8 bytes), and two fixed bytes (I think). That leaves room for up to 342 message bytes. WebThe three types of cryptography are symmetric, asymmetric, and hash values. The many examples of cryptography are DES, AES, RSA, and Diffie-Hellman key exchange. Cryptography has some challenges, including weak keys, insider threats, and incorrect use of keys.
