Which one to use: Managed vs. NonManaged hashing algorithms

Question

In a regular C# application which class to use for hashing: xxxManaged or xxx (i.e SHA1Managed vs SHA1) and why?

Answer 1

You should use the *Managed variants; they're usually faster.

The *CryptoProvider and *CNG classes use native interop, and are usually slower.
However, I've heard that they can use hardware crypto accelerators. (I haven't checked that)

Also, the native versions are FIPS-certified; the managed versions aren't.
