This system uses X.509 digital certificates for signing, meeting basic requirements of electronic signature law. Each signed contract contains:

• Signer's exclusive digital certificate
• RFC 3161 timestamp (proves signing time)
• Complete evidence chain (IP, browser, operation time, etc.)

These mechanisms effectively prove "who signed what content at what time", with evidentiary value in business disputes.

For highest legal validity, using government-issued citizen certificates for signing is recommended.

We take data security very seriously:

• All transmission uses HTTPS encryption
• Passwords stored using industry-standard hash encryption
• Contract documents stored on secure servers
• Your data is not shared with third parties
