Questions
that matter.
Straight answers about ProvSeal Verify.
Is the extension free?
Yes, verification is free and requires no account.
Why was it called C2PA Signer?
That was its first name. It is now called ProvSeal Verify, to avoid any confusion with the C2PA standard itself.
Can I try signing?
Yes, with a self-signed test certificate. It is never publicly recognised.
