Complete Privacy & Security
The file to be signed is encrypted with a 256-bit symmetric key generated in the user's browser before being uploaded to the server. This end-to-end encryption makes it technically impossible for anyone (including SecretSign's employees) without the key to view the file.
Signed files and signer data are also deleted from the server after 1-2 weeks. You can use the service without worrying about privacy or security.

Sign Any File
SecretSign uses a signature scheme that extends JSON Web Signature. This allows electronic signatures and timestamps to be applied not only to PDFs but also to images, videos, programs, and any other file type.
Files with signatures and timestamps prove when and by whom they were signed, helping prevent tampering.

Store signed files on your storage
SecretSign intentionally does not provide file storage or management functions. We encourage you to store signed files on your PC or cloud storage.
This approach allows us to reduce the costs associated with file management and security maintenance, enabling us to offer our services at a lower price.
Moreover, it is common for you and the other party to use different e-contract services. Managing all contracts with a single service is impractical.
We believe that managing signed files on users' PC or cloud storage is the most efficient way to handle contract management.
