Elba vs Picocrypt — tiny installer vs one HTML file

Picocrypt is a well-regarded, small cross-platform installer that encrypts files with Argon2 and XChaCha20. Elba is a single HTML file with AES-256-GCM and PBKDF2, delivered without an installer.

Pick Picocrypt if

You want Argon2's stronger resistance to custom hardware and don't mind installing a small binary per OS.

Pick Elba if

You want zero installation, one file that works everywhere with a Chromium browser, a declining one-time price, and mortalware licensing to 2030.

Questions people actually ask

Is AES-256-GCM weaker than XChaCha20?
No — both are considered strong. The difference is real but small at the primitive level.
Can I use both?
Yes. Some people use Picocrypt for archives and Elba for a working folder.

Take the island

Elba is one HTML file. It runs locally in a Chromium browser, seals a folder with AES-256-GCM, never phones home, and becomes open source on 1 January 2030.
