- fixed a bug in DB concerning loading of binary data
- added a warning to DB when an unknown type specifier is found (which
defaults to "char")
- fixed a bug in RSA code concerning loading of keys from a DB
- first successful test of client/server IPC ;-)
Now it basically works. I also fixed many bugs in the code which is not
used by programs, since it is under heavy development.
- reading keys from a file and writing then to a file now works
