Newbie Question - List of all available hash algorithms?

Hello,

I'm playing around with encryption/decryption, and I am trying to find all
the hashing algorithms that are available to .NET.  Specifically, I'm trying
to get all possibilities for the PasswordDeriveBytes.HashName property.  (I
couldn't find it on MSDN.)

Thank you,

Eric

Hello Eric,

by looking at the source with reflector - there is a HashTable with all available
algorithms. [0]

by experimentation - i found these to work (the others even produce a nasty
dialog box - so be careful if noone on your server is there to press enter
:))

MD5
SHA1
SHA256
SHA384
SHA512
HMACSHA1
