SafeNet Signing Server
Centralized digital signing for enterprises
SafeNet Signing Server is a centralized digital-signing system — a "digital notary office" inside your infrastructure. Instead of scattered USB tokens, every application simply sends a document and gets it back signed: "Send a document — get it back signed."
Traditional signing scatters USB tokens across machines, leaving signing keys dispersed and uncontrolled, each app re-implementing signing (and breaking standards), with no central audit trail. Scaling up only multiplies operating cost.
Features & capabilities
One synchronous API call
- Authenticate the calling application
- Use a signing key protected in a security device

- Software keys encrypted with AES-256, or kept in a certified HSM
- Layered checks: IP allowlist, API key and mTLS
- Append-only, sealed audit log
Scale & operations
- Stateless architecture, run multiple servers in parallel

Frequently asked questions
Does it replace USB tokens? +
Yes. Signing keys are centralized on the server (in an HSM or encrypted in the database) and apps call via API instead of plugging in a token.
Are my documents stored on the server? +
No. Documents are processed in memory during signing and returned immediately. The server only stores the document digest in the log, not its contents.
Can a signature still be verified years later? +
Yes, with a long-term level (B-LT / B-LTA): the signature embeds a timestamp and certificate-validation evidence.
