To use passwords encoded in the files of configuration, one will
do in the following way:
Modify the include file clecrypt.h by replacing the
values 0x00 which it contains by others of its choice:
(between 0x01 and 0x1F or 1 and 31
in decimal classification).
Remove if required the comment of the line : #include "clecrypt.h" in the file
Recompile tools using the key of encoding: make clecrypt
Only if Libremail was installed with the other commands of
the operating system, update this installation : make install
Lastly, one will launch the command cryptepass with all the files
of configuration which one wants to crypt the password (those whose 3rd
line starts with %pass ).
Notice about the safety of encoding:
It acts of a simple and reversible encoding. To guarantee the
confidentiality of the crypted passwords, it is recommended not to
keep the file clecrypt.h and achievable cryptepass
on the machine (and a fortiori on the account user) which contains
the configuration file with the crypted password.
For this reason the command make installdoes not recopy
the command cryptepass with the other commands of Libremail.
Nevertheless, without decoding the password, there will remain
possible with a third person to reach the mails if she recovers at
the same time the file of configuration and the commands described in
chapters 2 and 4 of this documentation.
Despite everything, if the same password is used for the management
of a Web site and for associated account email, this encoding will
make the password less visible. The command cryptepass of
Libremail or how it works, must be knowned to decrypt the password.
