tools.oxmo.org gathers text-handling tools that run on this server: JSON formatting and validation, encoding and decoding, hashes, and comparison of two texts.

What “self-hosted” means here

Processing happens on this server, in PHP, and the result comes back in the page. Nothing is sent to a third-party service, nothing is kept after the reply, and the content you paste is sent by POST — so it appears neither in the URL nor in the server’s access log.

There is a real trade-off, and you should know it: your text crosses the network to get here. For a genuine secret — a private key, a password — a tool running inside your own browser, or offline, remains preferable. This site does not claim to replace one.

No external resources

No remote fonts, no CDN, no library loaded elsewhere. The server’s content security policy forbids it, which makes the promise checkable in your browser’s network tab rather than merely stated.

The sister sites

ip.oxmo.org for everything about your address and the network, dns.oxmo.org for domain-name diagnostics. All three share the same server, the same design and the same rule.
