4.6.8.3 Manual verification of a file's authenticity
The easiest way to verify a file's authenticity is to use the Verify command in Acronis True Image
2021 or in the Acronis Cloud web application. Refer to Verifying file authenticity (p. 80) for details. In
addition to this easy method, you can perform the verification procedure yourself, step by step.
To verify a file's authenticity manually:
Step 1. Calculate MD5 hash of the file
1. Start Windows PowerShell.
2. For example, to calculate the md5 hash for the picture.png file located in C:\Users\picture.png,
type:
$($(CertUtil -hashfile "C:\Users\picture.png" MD5)[1] -replace " ","")
Example of an md5 hash: eea16ade1edf2750a46bb6bffb2e45a2
3. Check that the calculated md5 hash is equal to an eTag in the DATA field in your notarization
certificate. Refer to Verifying file authenticity (p. 80) for details about obtaining a file certificate.
Step 2. Check that a ROOT is stored in the blockchain
1. Open a blockchain explorer, for example https://etherscan.io/.
2. Enter the TRANSACTION ID from the certificate into the search field.
3. Check that the Data field in the Event Logs tab is equal to the ROOT value in your certificate.
