@xeals thanks in advance for looking into this error

Same same here ... both on 1.6 and 1.7a2 ... format incompatibility introduced by Signal App team since the previous release perhaps?

Windows 10 signal-back v0.1.7-alpha.2 proto commit: d6610f0

Yes, this utility is no longer compatible with current versions of Signal (I'm using this in May of 2020).

Every time I try to decrypt on Windows, I get this error. Different errors appear when building from source on MacOS or Linux. Have double-checked password, tried different instances of backup, different output types, all to no avail.

This should be considered a dead utility.

Yes, it's a shame that Signal does not offer an option to export SMS into the system's database. SMS are unencrypted anyway, so there's no point in worrying about security there.

I know this question is a bit off topic, but in case this program will not be able to convert Signal's new database format into a valid XML file correctly: what about the CSV file? If this program can create a valid CSV, that can be opened with LibreCalc or Excel without errors, shouldn't it be possible to re-import the message into the system database using this file? Does anyone know of an app or a program that can do this?
