Thanks for info.
I looked at the source code and I should be able to write a program to
decrypt the file, if needed. But I guess I will wait for the need to
show up.
I just want to make sure that if one day I am in a non-Windows
environment, I can retrieve my dat file from the network and run a
simple cmd line script to recover the passwords if needed.
When using PasswordSafe to generate the password, it is very unlikely
that I will even bother to remember them.
regards,
Arnaud
