Quickstart

Learn how to search and query SSH keys effectively.

First off, thank you for using sshark.app

Basic Search

Simply type a username or key content to search:

merlindorin

This automatically expands to @username:{merlindorin*} | @key:{merlindorin*}

Field-Specific Search

Use field prefixes with curly braces to search specific attributes:

  • @username:{merlindorin} — Search by username
  • @key:{AAAAC3NzaC1lZD*} — Reverse lookup by key content
  • @comment:{work} — Search in key comments

Available Fields

All fields are tag fields and use curly brace syntax:

FieldDescription
@idKey identifier (UUID)
@usernameOwner username
@sourcePlatform: github, gitlab, etc.
@providerProvider name
@typessh-rsa, ssh-ed25519, ecdsa-sha2-nistp256
@keyKey content (base64)
@commentKey comment

Tag Filters

Filter by source platform or key type:

  • @source:{github} — Only keys from GitHub
  • @source:{github|gitlab} — Keys from GitHub or GitLab
  • @type:{ssh-ed25519} — Only Ed25519 keys

Wildcards

PatternDescription
@username:{merl*}Wildcard — matches merlindorin, merlin, etc.
@username:{merlindorin}Exact match

Reverse Lookup

Have a key and want to find who owns it? Just paste the key content directly in the search box:

AAAAC3NzaC1lZDI1NTE5AAAAI...

Or use the field syntax for more control:

@key:{AAAAC3NzaC1lZD*}
