Ich habe versucht, mit Cyberduck auf den GMX Tresor zuzugreifen, aber das will bei mir nicht so ganz klappen. Theoretisch müsste das doch gehen, weil der GMX Tresor auf Cryptomator basiert oder verstehe ich da was falsch?

  • Resolution set to thirdparty
  • Status changed from new to closed

Unfortunately the vault format used in GMX Tresor is not interoperable with Cryptomator (albeit using the same implementation but adding deliberately a cryptographic pepper to make it incompatible).

Oh sorry, am I supposed to write in english?

I don't really understand much of what a pepper is, but when you search for "pepper", there is a match in C:\Program Files (x86)\GMX Tresor\app\GMX Tresor.cfg saying -Dtresor.pepper=gmx.

Maybe you can change Cyberduck in a way that one can enter or configure a pepper next to the password field of a Cryptomator folder?

  • Summary changed from Unterstützung für GMX Tresor to Interoperability with GMX Tresor format

Most likely this is the pepper used and we could add an option to enable the user to enter it alongside the passphrase input. Also we would need to add support for the renamed master key file systemdaten.gmxtresor.

Changes in r43843 to generalize the master key filename and pepper.
