WebCryptographic digests are typically between 128 and 512 bits. Though, both smaller and larger cryptographic hash functions do exist. For perspective, a 256-bit digest can be written as string of 64 hexadecimal digits, which can be comfortably printed on a single line of text. WebFeb 7, 2024 · Therefore, the implementation of quantum algorithms soon will be a reality. In classical computing, to factorize a large prime number takes a very long time, because the process to factorize an integer with n bits grows exponentially with n. Therefore, many classical cryptosystems exploit this complexity to encrypt data.
