OneSigner Service + GUI
Automated PDF & Code Signing Windows Service
OneSigner Setup (Free Trial)
OneSigner Service + Config GUI installer with the eSign portal. New in 2026.8.29: (1) Signing queue - concurrent signing requests from several users/CI jobs are now queued and served one after another by the USB token (HTTP 503 + Retry-After only if the token stays busy for the whole wait window, default 4 min); (2) Web Server tab (formerly Custom Domain): besides Cloudflare Tunnel you can now self-host over HTTPS with your own certificate - pick a certificate from the Windows store or a PFX file, choose the port, and the service serves TLS directly (needed for OneSignTool/AzureSignTool which require an https:// address); (3) Certificate lists in the Config app show token type (SafeNet/YubiKey/smart card/software), key algorithm, purposes (Document Signing / Code Signing) and expiry, with expired or unusable certificates flagged. Pairs with OneSignTool 2.1.0 (plain-language errors, automatic wait/retry while the token is busy). 30-day free trial. Signed by One Sign Pte. Ltd. Installer shows the End User License Agreement and requires acceptance; existing appsettings.json is never overwritten on upgrade.
