Upon arrival, I compute the SHA1 hash myself, using the same fields from the ASCII message and then try to verify if these fields were not altered by calling VerifyHash. The key is provided in 2 forms: regular and 'noNL'. WebSep 17, 2024 · Step 1 of my implementation is the following: Call from C# a SP with @Request nvarchar (max). The @Request contains a semicolon separated string. The first part is a random string, the second part is the X509 signed value (in hex) of part 1. The goal is that the SP can verify if @Request was really sent from the .NET client.
