I have never tried to decrypt Clipperz data with other tools.
We use standard crypto algorithms, but we have a custom way to encode
the data, so you will probably not able to decrypt them using OpenSSL
out of the box.
The main reason to go with a custom encoding schema was just that we
didn't want to deal with all the complexity of a standardized schema
that needs to take into consideration much more options than we really
needed.
Anyway, while working on the new release of the application, I would
be very pleased to improve the encoding in order to use a common
representation easily processable with other tools.
Any suggestion (and pointers) to a simple/convenient encoding schema
of encrypted data?
