SSH

SSH (Secure Shell) is a cryptographic network protocol for secure remote login, command execution, and file transfer between computers over unsecured networks. It provides strong encryption, authentication, and data integrity, replacing insecure protocols like Telnet and rlogin. SSH is a fundamental tool for system administration, DevOps, and secure infrastructure access. Multiple vendors provide SSH client libraries, server implementations, and management APIs.

SSH publishes 5 APIs on the APIs.io network, including Authorized Keys API, Certificates API, Host Keys API, and 2 more. Tagged areas include SSH, Secure Shell, Remote Access, Cryptography, and Network Security.

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

SSH’s developer surface includes authentication, documentation, engineering blog, and 10 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/ssh: open an issue to ask a question, or submit a pull request to add artifacts.
