Cryptographically - definition of cryptographically by The

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". WebMar 15, 2024 · What does it mean to be cryptographically secure? Well, there's always the boring definition of "nobody knows how to break it yet." But what happens when someone does break it? If you have specified a CSPRNG, you also have to include a way to query which algorithm is in use, or otherwise make it so that the end user can be certain of what … cam whynot elite prospectsWebNov 3, 2009 · That depends on what you mean by fast... There is no really fast secure random generator. If you want fast, you should use the regular Random class.
