Certified copy

Record of existence on the internet

Valid and verifiable Sealed on November 6, 2026, 12:55:14 (Central Mexico time)

Memoria y Resistencia hereby certifies que su sistema Turing leyó, el 6 nov 2026, 12:53:49 (hora del centro de México), la nota de bcs.gob.mx en el enlace público que se indica abajo; que guardó una copia de su contenido; y que la huella digital SHA-256 de esa copia fue sellada por un tercero independiente (FreeTSA, estándar RFC 3161) el 6 nov 2026, 12:55:14 (hora del centro de México). Cualquier cambio en el contenido, por pequeño que sea, cambiaría la huella, y el sello dejaría de coincidir.

INTERNET ARCHIVE · Wayback Machine

Backed up on archive.org

Internet Archive, an independent digital library, saved its own copy on its servers on November 6, 2026, 18:55 (UTC). We check its index to confirm it exists before showing it here.

Why does this make it authentic?
  • It is an independent witness. Internet Archive is a non-profit digital library that has preserved the web since 1996. It has no ties to Memoria y Resistencia or to whoever published the content.
  • The copy is theirs, not ours. Their own system captures it, stores it on their servers and stamps it with their own date and time. Neither we nor the publisher can edit it or change its date.
  • Anyone can verify it. It is at a public web.archive.org address that contains the date. Anyone can open it without asking us and compare it with our copy and its fingerprint.
  • It is a recognized reference. Journalists, researchers and lawyers often cite it to show what a page looked like on a given date.
  • Two witnesses that match. Our timestamp and the Internet Archive copy are made separately. If anyone claimed we altered the copy, the archive.org one would disprove it.

Internet Archive and its logo are trademarks of Internet Archive. We use them only to show where the copy is; this is not an endorsement by them.

IV Value as evidence

It is a technical proof of integrity and date. In Mexico, information recorded in electronic media is recognized as evidence, and its weight depends on the reliability of the method used to create and keep it, on its remaining intact and on its being available for later consultation (Commercial Code, art. 1298-A; Federal Code of Civil Procedure, art. 210-A; National Code of Civil and Family Procedure, art. 348).

This certificate meets those conditions with open standards that can be verified without trusting us: SHA-256 fingerprint, third-party RFC 3161 timestamp, OpenTimestamps on Bitcoin and independent copies at Internet Archive.

It does not replace a notarial certification of facts or a NOM-151 preservation certificate. If you need it for a lawsuit or a formal procedure, the same fingerprint can be backed by them: write to us with the folio.

V How to verify it yourself

  1. Descarga el sello (sello.tsr).
  2. Download from freetsa.org its certificates cacert.pem y tsa.crt, and check the timestamp: openssl ts -verify -digest 0925e0114a28c00862eb14a2c9fa7c666cb77e69adf60bab0e707eaa343f5739 -in ccpunaswz4-sello.tsr -CAfile cacert.pem -untrusted tsa.crt. It should say “Verification: OK”.
  3. The .ots file can be checked at opentimestamps.org. The Internet Archive copies open directly on web.archive.org.
