These are the jobs that come up in the middle of other work and are too small to justify opening an IDE or installing a package.

The hash generator computes MD5 (RFC 1321), SHA-1 and SHA-256 digests of a text. Use it to compare a value with a published checksum or to produce test fixtures.

MD5 and SHA-1 are broken for security purposes and should only be used where an existing system demands them; the page explains the difference. Base64 to image shows the picture hidden in a Base64 string or data URL, detects its real format from the file signature and lets you save it as a file.

The truth table generator evaluates a logic expression for every combination of its variables, which is handy for checking a condition before it goes into code or for coursework. The LaTeX table generator turns a grid of cells into tabular code with the special characters escaped.

All tools here run in your browser. Nothing you paste, whether a token, a snippet of production data or an internal URL, is sent anywhere. The site counts that a tool was used, never what was typed into it; the privacy page has the details.
