WebDec 12, 2024 · A cryptographic hash function can be used to generate (pseudo-) random bits of an apparent quality comparable to dedicated random number generators. I say "apparent" because although cryptographic hash functions are designed with some things in mind that are desirable features of random number generators as well (think e.g. … WebReturn a string of n random bytes suitable for cryptographic use. This function returns random bytes from an OS-specific randomness source. The returned data should be unpredictable enough for cryptographic applications, though its exact quality depends on the OS implementation.

WebIn the first meaning, a "generator" is defined to be an element that generates the entire group. That is, when we talk about DH (and thus the group Z p ∗ ), we say that g generates the entire group means g k mod p can take on any value between 1 and p − 1. In the second meaning, we say that an element g "generates" a subgroup. Webstream cipher: A stream cipher is a method of encrypting text (to produce ciphertext ) in which a cryptographic key and algorithm are applied to each binary digit in a data stream, one bit at a time. This method is not much used in modern cryptography. The main alternative method is the block cipher in which a key and algorithm are applied to ...
