3D Printers Log Decryptor

Static, client-side viewer for log_1 / log_2 files exported from some 3D printers via the USB export menu. Decryption happens entirely in the browser using the Web Crypto API — no file is ever sent to a server.

Tested models

• Anycubic FW 3.0.5+
• Centauri Carbon FW 1.4.49+

Usage

• Access the tool at 3d-printer-logs-decrypter
• Upload log_1 or log_2
• Check or download the decrypted output

Notes

• The AES-256-CBC key/IV are specific to log_1/log_2 log exports and were published by a community member on the Klipper forum.
• This does not decrypt firmware update.bin/update.swu packages — those use a different key and an MD5-checksummed header (see OpenCentauri).
