ASP.NET Membership: "Attribute not recognized 'hashAlgorithmType'" (SHA256)

Question

I want to use SHA256 as the hashalgorithmtype in my Membership Provider instead of the default SHA1.

<membership defaultProvider="AspNetSqlMembershipProvider" hashAlgorithmType="SHA256">
<providers>
   passwordFormat="Hashed"
   hashAlgorithmType="SHA256"/>
</providers>

This gives me the following error when I want to save to the Membership table: "Attribute not recognized 'hashAlgorithmType'"

Is there any way to solve this? Can't seem to find anything on the net...

Answer 1

I think it should look like this:

<membership defaultProvider="AspNetSqlMembershipProvider" hashAlgorithmType="yourAlgorithmType">
<providers>
   <!-- optional provider information here. just leave empty if you wish -->
</providers>
