SpletPBKDF2. PBKDF2 applies a pseudorandom function, such as hash-based message authentication code (HMAC), to the input password or passphrase along with a salt value and repeats the process many times to produce a derived key, which can then be used as a cryptographic key in subsequent operations. The added computational work makes … Splet03. okt. 2024 · SHA1PRNG algorithm is used as cryptographically strong pseudo-random number generator based on the SHA-1 message digest algorithm Note that if a seed is not provided, it will generate a seed from a true random number generator (TRNG). Why PBKDF2? Naturally in programming developers search for the fastest algorithm.
