dumpkeys

Export Chromium master keys as JSON for cross-host decryption.

dumpkeys exports the Chromium master keys as JSON, so you can decrypt the data on another machine with restore .

Note

dumpkeys is Chromium-only — Firefox and Safari have no exportable per-host key (Firefox re-derives one locally from key4.db; Safari reads the macOS Keychain).

Flags

FlagDefaultDescription
-b, --browserallTarget browser, or all
-o, --output(stdout)Output file; defaults to standard output
--keychain-pw(none)macOS login password for Keychain access

Examples

bash
# Print the Chrome master key as JSON to stdout
hack-browser-data dumpkeys --browser chrome

# Write keys for every detected Chromium browser to a file
hack-browser-data dumpkeys --output keys.json

Warning

keys.json holds plaintext master keys — anyone with it and the matching profile data can decrypt protected fields. File output requests mode 0600 where the platform supports Unix permissions; verify the actual mode or ACL, and prefer streaming over leaving it on disk.
