Panic during run-time

[tmplt]

I'm trying to decode a backup of mine via

$ signal-backup-decode signal.backup --password <password here> -o ./output --sqlite-path output/signal_backup.db

but the program panics with

thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: Error(MacVerificationError([194, 204, 123, 151, 76, 55, 140, 46, 209, 224], [253, 246, 15, 47, 113, 232, 242, 69, 170, 179]), State { next_error: None, backtrace: None })', libcore/result.rs:945:5
note: Run with `RUST_BACKTRACE=1` for a backtrace.

The full backtrace is

thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: Error(MacVerificationError([194, 204, 123, 151, 76, 55, 140, 46, 209, 224], [253, 246, 15, 47, 113, 232, 242, 69, 170, 179]), State { next_error: None, backtrace: Some(stack backtrace:

As the error says, there is an MacVerificationError. The mac is the Message Authentication Code Signal generates for every message in the backup. This usually happens if either the backup is corrupt or the passphrase is wrong. Please check that you entered the password as one large number, without spaces ("123451234512345123451234512345" instead of "12345 12345 12345 12345 12345 12345"). If the error still exists after you checked that, please reopen this issue
