In step 1, a simple file, which you create according to the instructions below, will be tamper protected with the HMAC-SHA-256 algorithm with a 128-bit key.
Note: The seal opening post should not be included when calculating seal in step 2.
See the technical specification for further details on how files are created.
- Create a file with eight zeros.
- Calculate the MAC on the file with the key specified below.
MAC (calculated cryptographic authentication code on the file) with the aforementioned key: MAC: FF365893D899291C3BF505FB3175E880Step 2
