Check this yourself

The timestamp token issued by Sectigo is available as a file. It is a standard RFC 3161 token, so you do not have to take our word for the timestamp — you can check it with OpenSSL on your own machine, against the audio file you hold.

Timestamp token (.tsr)TSA certificate chain (.pem)

Show OpenSSL commands

1. Check the token and its date

openssl ts -reply -in audiverify-timestamp-AUD-2026-FXL1PLOA.tsr -text

Prints the time Sectigo signed, and the SHA-256 value that was submitted to it. Anyone can run this on the downloaded token without an audio file. The token and chain files are supplied by Audiverify, but the signature inside them is Sectigo's, so OpenSSL checks it without relying on us.

2. Check that the token corresponds to your file

openssl ts -verify -data your-audio-file.wav \
  -in audiverify-timestamp-AUD-2026-FXL1PLOA.tsr \
  -CAfile sectigo-tsa-chain.pem

Run this against the audio file you hold. It hashes your bytes and compares them with the value inside the token, so only someone who has the original file can complete this step. It is not a check against any copy of ours.

This SHA-256 value was computed when the file was uploaded, then recomputed by Audiverify from the file it received. The two match, and this server-computed value was submitted to Sectigo.

What a passing check establishes

That this SHA-256 value existed at the time Sectigo signed it, and that the file you hold produces that same value. That is all. It says nothing about who wrote the music, who owns it, or whether any declaration on this page is true. The token is applied to the audio fingerprint alone, so it does not extend to the declarations or the attachments shown here.
