Electronic signatures and electronic seals are strong evidence at the moment they are created. The real challenge is time. Certificates expire, revocation information disappears, cryptography evolves and systems are replaced.
Docbyte preserves the validation evidence around signed and sealed documents so they can remain verifiable throughout the retention period. This preservation layer connects with Docbyte Vault, long-term archiving and Qualified Electronic Archiving when records need broader archive governance.
Most certificates are valid for one to three years. After expiry, you need preserved evidence to prove the signature or seal was valid at signing time. OCSP/CRL endpoints may no longer exist or issuing CAs may change infrastructure. Without preserved revocation evidence, validation becomes uncertain.
01
Cryptographic best practices evolve. What was acceptable at signing time can become weak later, requiring renewal of evidence via additional timestamping. Even if a signature is technically intact, your ability to interpret and present it consistently can degrade as viewers, libraries and systems change.
02
Many documents are stored as basic signatures without embedded validation info. Years later, you may have no reliable path to reconstruct the validation context. Long-term legal defensibility is not only cryptography. You also need traceability: who ingested the record, what controls applied, and whether any changes occurred.
Long retention without structured preservation means rising evidential risk.
03
Docbyte provides a preservation layer for documents containing electronic signatures, electronic seals and supporting evidence such as certificates, revocation information, timestamps and validation results.
The goal is practical: a future verifier should still be able to understand what was signed or sealed, whether it was valid at the relevant time, which evidence was preserved and which preservation actions were performed afterwards.
Capture and store the information required to validate the signature or seal later. Record validation results and the metadata needed for auditability. The evidence is captured while everything is still live and verifiable.
Ongoing preservation actions keep the evidential value demonstrable over time. Dependency on external endpoints that may disappear is reduced. Evidence is renewed proactively before it risks expiry.
End-to-end logging and reporting for compliance and evidential needs. Clear chain of custody for documents and all preservation events throughout the retention period.
Designed to fit into document generation, signing workflows and archives. Supports high-volume use cases: invoices, statements, contracts, regulated records.

Signature and seal preservation protects long-term verifiability. Qualified Electronic Archiving expands the scope to broader archiving controls: governed ingest, retention, legal hold, access control, audit trails and defensible disposal.
If signed records must remain not only verifiable but also governed as long-term business or regulatory evidence, the two should be considered together.
An electronic signature is associated with a natural person and supports personal authentication. An electronic seal is associated with a legal entity and demonstrates the origin and integrity of a document. Docbyte preserves the long-term evidential value of both, using EU terminology aligned with eIDAS.
Today’s validation relies on live infrastructure: certificate chains, OCSP services, trusted lists. Over time, that infrastructure changes. Preservation captures the evidence needed to validate the signature or seal independently of live services, years or even decades later.
No. Preservation adds evidence around the document (evidence records, timestamps, audit trail) without altering the original content or its embedded signature or seal.
There is no fixed upper limit. Retention periods are configured per record type. Preservation actions are performed proactively to maintain verifiability throughout, regardless of the duration.
Docbyte can preserve electronic signatures and electronic seals at multiple assurance levels, depending on your ecosystem and policy. The exact scope and controls should be discussed based on your use case.
Typically: the document itself, certificate chain, revocation information, timestamps, validation results, and audit log of preservation actions. The precise scope depends on the document type and policy.
No. Signature and seal preservation addresses the verifiability dimension. QeA adds broader archiving governance: controlled ingest, retention, legal holds, auditable disposal, and full defensibility of the archiving process. The two are complementary.
Docbyte’s preservation approach is designed to handle cryptographic evolution. Evidence records are renewed and updated proactively before existing protections expire, maintaining a continuous chain of verifiability.
Yes. Docbyte can integrate with upstream signing platforms, document management systems, and downstream archiving workflows via API. High-volume ingestion from signing platforms is supported.
