Web21. Symmetric encryption does not provides integrity. The amount of control that an attacker can have on encrypted data depends on the encryption type; and some specific details of … WebOn the other hand, a hash function, H(.), is that function which takes as input data with an arbitrary length and produces as output a fixed-sized string of hash value, h [20]. WebMay 10, 2024 · Hash functions are very similar to symmetric ciphers and they involve the same concepts of confusion and diffusion. In fact, hash functions are sometimes used to create ciphers, and vice versa †. This can be seen with Salsa20, a stream cipher that uses a hash at its core, and Whirlpool, a hash function which uses a modified version of AES. hauskauf von privat an privat
