Hi,

I have an application that uses the SHA1 algorithm to verify
the authenticity of encrypted (or signed) data using the
VerifyData method of the RSACryptoServiceProvider class.

I'm sure you all know that this method also uses the
public key corresponding to the private key that the data
was encrypted with, as well as a digital signature to
compare the decrypted signed data with.

Usually, for some given signed data, I get 'true' returned from
this function. However, on a few machines, I am getting a 'false'
returned, even though I am using the same signed data, signature
and public key. This makes me wonder - could the encryption
algorithm be corrupted somewhat? Is there a place in the computer
I can check to see this?

TIA,
