WebMay 23, 2024 · Chi-square test cannot prove that a random number generator is cryptographically secure. All it can do is show that the RNG is not subject to certain types of biases — but this is not even sufficient to show that it's a good PRNG, let alone that it's secure! – user149341 Apr 12, 2013 at 0:02 Add a comment Your Answer Post Your Answer WebHMAC. In cryptography, an HMAC (sometimes expanded as either keyed-hash message authentication code or hash-based message authentication code) is a specific type of message authentication code (MAC) involving a cryptographic hash function and a secret cryptographic key. As with any MAC, it may be used to simultaneously verify both the data ...

This term "cryptographically strong" is often used to describe an encryption algorithm, and implies, in comparison to some other algorithm (which is thus cryptographically weak), greater resistance to attack. But it can also be used to describe hashing and unique identifier and filename creation algorithms. See for example the description of the Microsoft .NET runtime library function Path.GetRandomFileName. In this usage, the term means "difficult to guess". Web1.
