Document verification for advanced electronic signatures
Verify documents signed in TramitApp and check that they have not been altered. Simply upload or drag in the signed document and the OTS file you received after signing (the tool is in Spanish).
The hash check runs entirely in your browser to protect your privacy.

The European eIDAS Regulation
European Union Regulation No 910/2014, known as the eIDAS Regulation, sets out the common legal framework for electronic signatures across the European Union. The eIDAS Regulation lays down the requirements an advanced electronic signature must meet:
- It must be linked to the signatory in a unique and non-transferable way.
- It must allow the signatory to be identified.
- It must be created using data that the signatory can use and that is under their sole control.
- It must be linked to the signed data in the document, thereby preventing any later modification of that data.
How TramitApp's advanced electronic signature works
Following the requirements laid down by eIDAS, TramitApp's advanced electronic signature meets every specification needed to sign documents online with full legal guarantees and legal validity.
Proof of identity:
The user must be logged in to the platform. We record the device from which the user accesses their profile.
Integrity:
Control over both the device and the app.
Timestamping
Also known as proof of time or timestamping.
Informed signature:
The signatory must know what they are signing. In TramitApp, the user has to open the document before they can sign it.
Benefits of the OpenTimestamps (OTS) system
Independent verification
OpenTimestamps is decentralised and removes third parties such as certificate authorities.
It's free
Timestamping documents costs nothing extra.
The certificate cannot be revoked
Blocks on the blockchain cannot be modified.
It scales
An unlimited number of documents can be timestamped in the same transaction.
Understand the basic concepts
What is timestamping?
A timestamp is a cryptographic proof generated from a document on a given date. Anyone who holds the original document and its timestamp can check that the document existed and has not been modified.
How is document integrity guaranteed?
When a document is signed with TramitApp, the document's hash is generated automatically and added to OpenTimestamps. The system places that hash in a Merkle tree and records it in a transaction on the Bitcoin blockchain.
This makes it possible to verify that the signed document has not been modified in any way.
What is OpenTimestamps?
It is an open standard for Bitcoin timestamping, used to prove that documents existed.
FAQs on document verification with an advanced electronic signature
How do you verify that an electronic signature is authentic?
To verify that an electronic signature is authentic, you need to check the evidence these signatures generate. The main pieces of evidence include a proof of time or timestamp, the integrity of the document, a check of its timestamp, and an informed signature.
How legally valid is a digital signature?
If you use a tool that produces a recognised electronic signature, it has full legal validity and is equivalent to a handwritten signature on paper. A simple digital signature, on the other hand, offers no legal guarantee as to the identity of the signatory, and it is also easy to forge.
How do you certify a digital signature?
To certify a digital signature, you need to check that the document could not have been altered once it was signed. At TramitApp we use blockchain technology to guarantee the integrity of the document and provide a secure timestamp.
How do you check a digital signature in a PDF?
A digital signature added to a PDF is very unlikely to hold up as evidence in court, because it does not meet the requirements of the European eIDAS Regulation. Checking it, therefore, gives you no guarantees.
How can you tell whether a document has been digitally signed?
An electronic signature generates a set of evidence that must be attached once the signing process is complete. So everything you need to know whether a document has been digitally signed should be visible in the signed document itself.
How do you sign a document with an electronic signature?
With the right tool, you can sign a document electronically from your mobile or on the web. Open the document you want to sign and draw your signature by sliding your finger across the screen or using your computer mouse. Software such as TramitApp makes this simple process possible.
