https://getcroc.com/blog Seven notes on why I built croc this way: live relays, PAKE encryption, four-word codes, browser transfers, and temporary storage. en-US https://getcroc.com/blog/why-croc-works-this-way https://getcroc.com/blog/why-croc-works-this-way Sat, 08 Aug 2026 00:00:00 GMT croc started with a large documentary, a friend in another country, and the surprisingly difficult question of how to send her the file. https://getcroc.com/blog/how-croc-moves-a-file https://getcroc.com/blog/how-croc-moves-a-file Sat, 08 Aug 2026 00:00:00 GMT The croc relay looks a little like an upload server, except it does not wait for the whole file before sending it onward. https://getcroc.com/blog/what-four-word-code-does https://getcroc.com/blog/what-four-word-code-does Sat, 08 Aug 2026 00:00:00 GMT I wanted a croc code to be easy to read aloud. Making four ordinary words secure enough for a file transfer takes a little more work. https://getcroc.com/blog/pake-step-by-step https://getcroc.com/blog/pake-step-by-step Sat, 08 Aug 2026 00:00:00 GMT PAKE is the part of croc that turns a small shared phrase into a strong key. Here is the exchange without skipping the interesting bits. https://getcroc.com/blog/send-file-from-browser https://getcroc.com/blog/send-file-from-browser Sat, 08 Aug 2026 00:00:00 GMT The browser can join an ordinary croc transfer now. Choose the files, share the code, and keep the tab open until the handoff finishes. https://getcroc.com/blog/browser-meets-terminal https://getcroc.com/blog/browser-meets-terminal Sat, 08 Aug 2026 00:00:00 GMT The browser client was meant to join normal croc transfers, not become another file-sharing island with its own links and accounts. https://getcroc.com/blog/stored-transfer-one-download https://getcroc.com/blog/stored-transfer-one-download Sat, 08 Aug 2026 00:00:00 GMT Direct croc transfers expect both computers to be awake. Stored mode is for the inconvenient times when the people are not.
