LumasSigning, encryption and access control
Sign, encrypt and restrict documents without a third-party service
Digital signatures, encryption and permissions applied inside your own process, with your own keys.
The problem
Signing and encryption are the parts of a document workflow most likely to be outsourced — and the parts where sending the document to somebody else is hardest to justify to a security review.
The approach
Apply the signature and the encryption in your process, with keys that never leave your infrastructure. The document does not travel to a third party to become secure.
How you can check it
The signature and encryption APIs are documented and counted on their capability pages, and the produced files are verified against third-party readers in the SDK build.
Prove it on your own documents
Public download, no account. Run it against the files you actually have before anyone signs anything.
