In Machine.config we have the following element
<machineKey validationKey="AutoGenerate|value[,IsolateApps]" decryptionKey="AutoGenerate|value[,IsolateApps]" validation="SHA1|MD5|3DES"/>
In validation we can mention any one of the alogorithms(SHA1, MD5 or 3DES)
SHA1 will be used for integrity check only. It is just a hashing algorithm.
And 3DES be used for encryption.
My Question is why we can't specify SHA1 and 3DES, which provides integrity and encryption.
