What is a C2PA Certificate?
The cryptographic anchor for content provenance.
A C2PA (Coalition for Content Provenance and Authenticity) Certificate is a digital certificate used to sign a C2PA manifest, the structured provenance record embedded in a media file. The certificate proves that the manifest was created by the named entity and hasn't been tampered with since signing.
When a platform, viewer, or tool inspects a content credential, it validates the C2PA certificate signature, confirming the credential is authentic and unaltered.
A C2PA Certificate lets you attach a cryptographically signed provenance record, a “content credential,” to any media file. Anyone who receives the file can verify its origin, check whether it’s been altered, and see an auditable chain of custody from creation to distribution. Built on the open C2PA standard, backed by Adobe, Google, Microsoft, BBC, Reuters, Sony, Nikon and the broader Content Authenticity Initiative.

Process
Here are the steps you’ll need to go through to get stated with C2PA in your products:
Compliance & standards
C2PA Specification (v2.x)
SSL issues certificates per the C2PA specification. C2PA Claim Signing certificates from Trust List CAs are the norm since C2PA 2.2.
C2PA Trust List
As of 1 January 2026, the C2PA Trust List replaced the Interim Trust List. Validators are no longer required to validate content signed via the Interim Trust List.
RFC 3161 (Time Stamping)
Trusted timestamps from SSL's TSA provide long-term validation for signed manifests
EU AI Act
Requires disclosure of AI-generated content. C2PA manifests provide a standardized, machine-readable disclosure mechanism.
Content Authenticity Initiative (CAI)
SSL is a CAI member. C2PA certificates issued by SSL are part of the CAI trust framework.
Frequently asked questions
Yes. Since June 2026 the SSL C2PA Free Tier includes one Level 1 Claim Signing Certificate (valid for 1 year) and 10,000 trusted timestamps per year, issued via the SSL portal. You need to apply with a valid C2PA conformance record ID. If you need Level 2 certificates, device certificates, or conformance support contact us for our Premium tier.
A C2PA Certificate signs the content manifest, proving it is coming from a conformant generator (e.g., a tool or device). A CAWG Identity Assertion embeds your verified organizational or personal identity inside the manifest. They complement each other: use both for maximum attribution and trust.
Without a trusted timestamp, a manifest stops being valid once the signing certificate expires or is revoked. A timestamp coming from a Trusted Time Stamping Authority like SSL lets validators confirm the claim was signed while the credential was valid, so the manifest can be validated indefinitely. See the Time Stamping Authority product page.
Yes, you can sign existing content with a C2PA manifest. However, provenance established at the point of creation is more authoritative than retroactive signing. Best practice is to sign at capture or creation.
C2PA supports JPEG, PNG, TIFF, WebP, MP4, MOV, MP3, WAV, HEIC, PDF, live video, text and others. Support is expanding as the standard matures.
Recipients can verify content at verify.contentauthenticity.org without any special software. C2PA-aware tools (Adobe apps, LinkedIn, browsers via extensions) display credentials inline.
