GDCA SSL 
SSL Certificates in the GDCA Digital Security era are digital certificates that protect the security of data transmission between servers and clients. They have data encryption and identity authentication functions to ensure the integrity and privacy of information transmission.

AboutGDCA
GDCA Digital Security Times is an authoritative CA certificate authority certified by WebTrust and has international electronic certification service capabilities. Its SSL Certificates include pure domestic SSL Certificates and national secret SSL Certificates. Purely domestic SSL Certificates adopt the length of RSA2048 encryption algorithm. All key service facilities are deployed domestically. The speed of verifying certificates is better than that of foreign brands. It supports all mainstream operating systems and software libraries, and is suitable for national enterprises, government agencies, etc. National Secret SSL Certificates support SM2 domestic cryptographic algorithm and national secret security protocol. They use the national secret algorithm to achieve high-strength SSL encrypted connections and server identity authentication. They support national secret browsers and are suitable for websites that require national secret compliance. Regardless of the type of SSL Certificates, GDCA Digital Security Era is committed to providing safe, reliable and efficient website security protection solutions.
