# Certificate information

Available in Classic and VPC

You can obtain and use SSL/TLS certificates from NAVER Cloud Trust Services, a trusted certificate authority.

              Caution

              

Issued certificates work properly on compatible operating systems and software. Before use, be sure to check the [compatibility of the issued certificate](/docs/en/certificatemanager-cmissuedcertificate-feature#%EB%B0%9C%EA%B8%89%EB%B0%9B%EC%9D%80%EC%9D%B8%EC%A6%9D%EC%84%9C%EC%9D%98%ED%98%B8%ED%99%98%EC%84%B1).

## Compatibility of issued certificates

Check the operating system and software versions that support certificates issued by NAVER Cloud Trust Services.

- Visit the [test website](https://test-certificate.naver.com/), which uses an issued certificate, to check in advance whether your operating system and software work properly with the certificate.
- If the client environment using SSL/TLS communication is an incompatible version or software, the NAVER Cloud Trust Services root certificate must be installed in the client environment to enable normal communication. To install the root certificate, see [Certificate compatibility and root certificate installation](/docs/en/certificatemanager-troubleshoot-compatibility).

## JAVA compatibility

Check the JAVA OpenJDK providers and versions that support certificates issued by NAVER Cloud Trust Services.
