[CryptoAPI] Validating an MD5 Checksum
Forge component by Ricardo Silva

Hi All,

I am trying to validate that a file we are being sent matches a checksum that is also being provided.  The checksum has been calculated by running the command prompt "certutil -hashfile {filename} MD5" and this provides me with a 32 character string.  

Is there a function inbuilt in this component that allows me to run across the file and receive a code to be matched to validate that the file hasnt been tampered with?  

I have tried the "ComputeHash" function passing my file binary in (converted from BinaryDataToText) and "MD5" in the Algorithm but doesnt seem to match.

Any advise would be great

Hi Daniel,

With powershell component you can validate any file directly on the server with certutil.
