This is second post of mutt tutorial series. As in the previous post for below information I need to thank Kousik for posts about gpg and using it with mutt. But probably the most important to simplify this method was Fau comment here. So going to the point of secure login for mutt we need gpg. First of all we need to install it by simply:
|
|
After that we generate our keys by:
|
|
I choose all default answers. So first is key type: 'RSA and RSA'. Second -
keysize: 2048. Third - time for key expiration: '0 = key does not expire'.
After that you need to identify your key with some data. This data will be used
to find your key so IMHO it should be short and simple but meaningful. At the
end of this process you will be asked about pass phrase, which will be used to
decrypt files encrypted with generated key. When you end with key generation you
can encrypt file with passwords. Best way to do this is to write some script
that will be sourced by mutt after decryption. For storing passwords I create
directory in my $HOME:
|
|
Inside this directory I create text file with the script, which look like below:
|
|
This script of course mean to set value of variable name my_isp{1,2,3} to some
password string. Remember to use my_ prefix because this is the way that user
variables should be defined in mutt scripts. After writing this file we need to
encrypt it.
|
|
Now we should delete txt file. To use our newly created encrypted password
script we need to add some lines to $HOME/.muttrc. So vim $HOME/.muttrc.
Line that we need before sourcing encrypted scripts is declaration of variables
in the script:
|
|
After this line we can source and decrypt out file with the passwords:
|
|
At the end we need to replace all out plain text passwords (smtp_pass and
imap_pass variables) with variables defined in out encrypted file. This
settings will cause that mutt during start will run gpg to ask about password to
decrypt password script file. In the next post I will discuss mutt with
sidebar and how to open html files from inside mutt.
