SHA1Managed() not found

[NareshShroff]

Hi,
im doing a pocket PC application in VB.net.
Im trying to hash a password using SHA1Managed(), but im getting an error saying SHA1Managed is not found.

-----------------------------------------
Dim shaMged As New SHA1Managed()
-----------------------------------------

i imported namespace: System.Security.Cryptography

but still getting error.

i even tried System.Security.Cryptography.SHA1 but i dont have that namespace on my system. I mean its not showing in dropdown menu. Kindly help me out

Thanks in advance

Naresh, Take a look at these very noce articles and sample code on hashing.


ASP.NET provides a very convenient way to create a hashed string from a user inputted value. A common issue with storing passwords in flat file or even the database, is that unwanted eyes can potential see your users passwords and hack into your web application. In order to hide users passwords in the database, you can create a hashed value of the password and store it in the database. The benefit of storing a hashed value for your passwords is that other people will never know the actual password. The drawback of this approach is of course if you forget the password, its very hard to recover.
