Sign under your agency name
While you evaluate, signing runs under the Encypher platform identity. Your agency name appears on an eligible paid plan, once we accept your identity proof.

C2PA 2.4 Content Credentials for your ad creative.
Sign supported ad creative with C2PA 2.4 Content Credentials. Review signer identity, source declarations and ingredient provenance against your client brief. Add watermarking where your workflow calls for it.
The request takes a name, an email, a format, and the clause your client sent. No client asset upload required. We will review the requirement and agree the next step. See Mark pricing

Identity. Ingredients. Acceptance.
Answer the clause in the brief.
When your client asks for Content Credentials, signer identity, or ingredient provenance, start with their specification. Check one deliverable before changing your production workflow.
02
Show where the artwork came from
Link source assets and preserve their existing credentials. Your client can inspect the declared ingredients and actions. Missing source credentials remain a gap to resolve.
03
Test against their check
It depends on the tool your client checks with. We agree that check up front, then run your real export and delivery path.
What the client opens
One deliverable, checked by anyone.
The card below is a labeled example of the fields a check returns. Real signed creative, with the output it gives back, sits on the examples page.
Signed deliverable
Labeled example- Signer
- Your agency, on a paid plan with accepted proof
- Credential
- C2PA 2.4, with a signing time
- Ingredients
- Source references and available credentials
Signing under your own agency name needs an eligible paid plan and accepted identity proof. A watermark does not replace a source declaration your client asked for.

Real files first. Forms later.
Open a signed image, read the source history behind it, then check the coverage table against the formats you ship.

What we sign, what we check, and which version applies, format by format.
Read the coverage tableHow it works
From one clause to one accepted file.
The first pass can use your own artwork or ours. Client files move by secure transfer after the intake, and we do not host them in public by default.
- 01
Send the clause
A name, an email, a format, and the clause your client sent. No asset upload.
- 02
Agree the scope
We confirm the formats, the signer, the source inputs, and the check your client accepts.
- 03
Sign and deliver one
We sign a sample, you run your real export and delivery path, then we read the result together with the gaps named.
Proof details
Coverage and client acceptance
Encypher supports 70+ formats for signing and verification. We check the agreed technical requirements; your client decides whether to accept the deliverable.
- C2PA 2.4 is the default signing version. Version support varies by format: 67 of the 70 formats list it today.
- Our audio and video examples show that the credential is present and valid. They do not show that a watermark survives a transcode.
- Our formal C2PA conformance record covers version 2.2 over 20 media types. That record is narrower, and it is not a 2.4 pass.
