Everyday Hosting Tools
Generate stronger passwords, inspect live SSL certificates, run service checks, and use quick conversion tools from one place.
Passwords
Build random passwords with configurable numbers, symbols, and letter counts.
Open password toolsSSL Tools
Generate RSA or ECDSA CSRs, inspect certificates, match keys, and convert PEM, DER and PFX formats.
Open SSL toolsService Checks
Investigate DNS, mail policies, HTTP responses and TLS certificates on public services.
Open service checksConversions
Convert MAC addresses to IPv6 EUI-64, work out power usage, and estimate bandwidth usage or transfer times.

Understand your hosting configuration
Use these tools to troubleshoot public hosting services, prepare certificates for deployment, and collect evidence for a support request.
DNS and email configuration
Inspect A, AAAA, CNAME, NS, SOA, PTR, MX, TXT and CAA records with their returned TTLs. Compare answers from this hosting server’s DNS resolver, Google, Cloudflare or a custom public resolver to investigate differences.
Check SPF dependencies, DKIM public keys and DMARC policies. These checks explain published configuration; verifying an email's authentication also requires the message and sender context.
Inspect DNS recordsLive TLS and HTTP diagnostics
Inspect certificate names, expiry dates and verification results on HTTPS and other public services, including custom ports. Choose direct TLS, mail upgrades, explicit FTPS, PostgreSQL or MySQL/MariaDB negotiation.
Trace HTTP redirects, status codes and connection timings, or review response security headers. Checks run from this server, so results can differ from your own network.
Test a TLS service Trace an HTTP requestCertificate preparation and inspection
Create RSA or ECDSA P-256/P-384 certificate signing requests with DNS and IP subject alternative names (SANs). Decode certificates, compare public-key fingerprints across certificates, CSRs and private keys, and convert certificate formats.
Matching keys confirms they belong together; it does not establish issuer trust, revocation status or the identity of a live service.
Explore certificate toolsDomain health reports
Bring DNS, registration, HTTPS, security headers and mail policies into one report, with optional service TLS checks. Each check includes its evidence, observation time and suggested next action.
Copy a summary, download JSON or print the results for a support ticket. Cached public lookups show their freshness, and incomplete checks remain visible.
