1 This file describes how to configure mutt to use S/MIME.
3 This file is almost the same as smime-notes.txt available in mutt upstream
4 sources, but it contains a few modifications about Debian-specific issues.
6 Mutt needs some user interaction to get it ready for S/MIME.
8 1. Make sure, that openssl (must be) and ca-certificates (recommended)
9 are installed. If not, ask your administrator to do it.
11 2. Run 'smime_keys init'.
13 3. If ca-certificates is installed, make a symlink:
14 ln -s /etc/ssl/certs ~/.smime/ca-bundle.crt
15 If not, there are some other packages which contain Root CA certificates,
16 for example: kdelibs-data, libcurl2.
17 This makes you trust anything that was ultimately signed by one of CA
18 included in symlinked crt file.
20 4. Get yourself a certificate. (You can get one for free from www.thawte.com,
21 or pay for one from VeriSign or one of its competitors). The way the
22 process generally works: the certificate will be installed "into" your web
23 browser. If you are asked what application you wish to use the
24 certificate with, select Netscape. Strangely enough, "mutt" is usually not
27 5. Assuming you are using Mozilla, follow the instructions at
28 www.verisignlabs.com/Projects/smime_docs/linux.html to export the
29 certificate into a file called cert.p12. If you don't use Mozilla, you're on
32 6. Run 'smime_keys add_p12 cert.p12'.
33 * When the script asks for the "Import password", enter the one you
34 provided when you exported the certificate
35 * When it asks for a "PEM pass phrase", make up a new password. Every
36 time you sign or decrypt a message, mutt will ask for the PEM passphrase
37 * Finally, when the script asks for a label, enter an easy-to-remember
38 name for the certificate, such as "me". The script output will include
40 added private key: /home/raldi/.smime/keys/12345678.0 for raldi@verisignlabs.com
41 The number (including the ".0" at the end) is your keyid. You will
42 need this number in the next step.
44 7. Edit your .muttrc file and add a lines:
45 set smime_default_key=keyid
46 set smime_sign_as=keyid
47 Probably you also want to change default values for smime_timeout
48 and smime_encrypt_with originally set in global /etc/Muttrc
50 8. Optionally, you can add following line to your ~/.mailcap to view certificate
52 application/x-pkcs7-signature;openssl pkcs7 -in %s -inform der -noout -print_certs -text | pager; needsterminal
