What's the NOM-151?

The NOM-151- SCFI - 2016 (Official Mexican Standard) lays down technical and legal requirements for data message maintenance and document digitization in Mexico. It is issued by the Ministry of Economics.

When a sign includes certification NOM-151, an Certification Service Provider (PSC) authorized issue a time stamp that: records the exact date and time, links the document's SHA-256 and stores it in a verifiable string.

Any subsequent modifications to the document invalidate the hash and are immediately detectable. That makes the signature practically irrefutable in a legal process.
