SSL/TLS

SSL/TLS (Secure Sockets Layer / Transport Layer Security) is the cryptographic protocol that secures communications over the internet. TLS 1.3 is the current standard, providing authentication, confidentiality, and integrity for HTTPS, email, VoIP, and other protocols. This covers certificate management, public key infrastructure (PKI), certificate authorities, and TLS configuration APIs from major vendors and open source projects.

SSL/TLS publishes 5 APIs on the APIs.io network, including Certificates API, Domains API, Monitoring API, and 2 more. Tagged areas include SSL/TLS, TLS, Certificates, PKI, and Cryptography.

The SSL/TLS catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.

SSL/TLS’s developer surface includes authentication, documentation, engineering blog, and 11 more developer resources.
