Certified copy

Record of existence on the internet

Valid and verifiable Sealed on November 14, 2026, 13:14:36 (Central Mexico time)

Memoria y Resistencia hereby certifies que su sistema Turing leyó, el 14 nov 2026, 13:10:19 (hora del centro de México), la nota de Cambio de Michoacán 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 14 nov 2026, 13:14:36 (hora del centro de México), y respaldada por separado en Ghostarchive. Cualquier cambio en el contenido, por pequeño que sea, cambiaría la huella, y el sello dejaría de coincidir.

GHOSTARCHIVE · ghostarchive.org

Respaldada en Ghostarchive

Ghostarchive es un archivo público e independiente, sin relación con Memoria y Resistencia ni con quien publicó. Guardó its own copy de la página el 14 nov 2026, 15:02:15 (hora del centro de México). Acepta sitios que Internet Archive no guarda, como X.

Why does this make it authentic?
  • It is an independent witness. No tiene relación con Memoria y Resistencia ni con quien publicó.
  • The copy is theirs, not ours. La guarda en sus servidores con su propia fecha y hora. Ni nosotros ni quien publicó podemos editarla.
  • Anyone can verify it. Se abre sin pedirnos permiso y se compara con nuestra copia y su huella.
  • Two witnesses that match. Nuestro sello de tiempo y la copia de Ghostarchive se hacen por separado. Si alguien dijera que alteramos la copia, la de Ghostarchive lo desmiente.

Ghostarchive es un servicio de terceros. Lo usamos solo para indicar dónde está la copia; no es un aval de su parte.

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).

Este certificado cumple esas condiciones con estándares abiertos, comprobables sin confiar en nosotros: huella SHA-256, sello de tiempo RFC 3161 de un tercero, OpenTimestamps sobre Bitcoin y una copia independiente en Ghostarchive.

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. Download the seal (sello.tsr).
  2. Download from freetsa.org (opens in another tab) its certificates cacert.pem y tsa.crt, and check the timestamp: openssl ts -verify -digest 82b89bbfb332b4bee45eae48ee651ca64bac3705a002f6f8efde0c8a019b1274 -in cc9rpczmxe-sello.tsr -CAfile cacert.pem -untrusted tsa.crt. It should say “Verification: OK”.
  3. The .ots file can be checked at opentimestamps.org (opens in another tab). La copia de Ghostarchive está en https://ghostarchive.org/archive/0AjRA (abre en otra pestaña).

How to use the timestamp (sello.tsr)

It is the stamp signed by FreeTSA, an independent third party, under the RFC 3161 standard. It proves the copy's fingerprint already existed at that date and time, and that nobody changed it afterwards.

  1. Download the stamp and save it in a folder.
  2. Download from freetsa.org (opens in another tab) its certificates cacert.pem y tsa.crt, and put them in the same folder.
  3. Open the Terminal in that folder (you need OpenSSL; it already comes on Mac and Linux) and type:openssl ts -verify -digest 82b89bbfb332b4bee45eae48ee651ca64bac3705a002f6f8efde0c8a019b1274 -in cc9rpczmxe-sello.tsr -CAfile cacert.pem -untrusted tsa.crt
  4. If you answer «Verification: OK», the seal is authentic. To view the stamped date and time:openssl ts -reply -in cc9rpczmxe-sello.tsr -text

Before you download · Step by step

How to use the OpenTimestamps proof (sello.ots)

It is the proof that the copy's fingerprint was recorded on the Bitcoin blockchain, a public record nobody can alter or delete.

  1. Download the .ots file.
  2. Go to: opentimestamps.org (opens in another tab) and drag the .ots file to the box on the page.
  3. The page shows you the registered fingerprint. It must be:82b89bbfb332b4bee45eae48ee651ca64bac3705a002f6f8efde0c8a019b1274
  4. It will tell you in which Bitcoin block and on what date it was recorded. If it says it is still pending, try again in a few hours.
