If </para> </tip> + <sect2 id="encryption-smime"> + <title>S/MIME Encryption</title> + <para> + S/MIME encrpytion uses a key-based approach as well, but it + has some significant advantages in convenience and + security. S/MIME uses "certificates," which are basically + the same as keys. The public portion of each certificate is + held by the sender of a message and by one of several + certificate authorities, who are paid to guarantee the + identity of the sender and the security of the + message. Evolution already knows a large number of + certificate authorities, so when you get a message with an + S/MIME certificate, your system will automatically get the + public portion of the certificate and decrypt or verify the + message. + </para> + <para> + S/MIME is used most often in corporate settings. In these + cases, administrators supply certificates which they have + purchased from a certificate authority. In some cases, an + organization can act as its own certificate authority, with + or without a guarantee from a dedicated authority such as + Verisign or Thawte. In either case, the system administrator + will provide you with a certificate file. + </para> + <para> + If you wish to use S/MIME independently, you can extract an + identification certificate from your Mozilla or Netscape web + browser. See the Mozilla help for more information on + security certificates. + </para> + + <para> + The certificate file is a password-protected file on your + computer. To use it in Evolution, select <menuchoice><guimenu>Tools</guimenu> + <guimenuitem>Settings</guimenuitem></menuchoice> and select + the <guilabel>Certificates</guilabel> tool in the settings + window. Click the <guilabel>Import</guilabel> button and + select the file when prompted. + </para> + <para> + Similarly, you can add certificates which are sent to you + independently of any authority by clicking the + <guilabel>Contact Certificates</guilabel> tab and using the + same <guilabel>Import</guilabel> tool. You can also add new + certificate authorities, which have their own certificate + files, in the same way. + </para> + <para> + Once you have added your certificate, you can sign or encrypt a message by selecting <menuchoice> + <guimenu>Security</guimenu> <guimenuitem>S/MIME + Sign</guimenuitem></menuchoice> or <guimenuitem>S/MIME + Encrypt</guimenuitem> in the message composer. To have every + message signed or encrypted, select an email account in the Settings dialog (<menuchoice> + <guimenu>Tools</guimenu> + <guimenuitem>Settings</guimenuitem></menuchoice> and, under the + <guilabel>Security</guilabel> tab, check the appropriate + box. You can also import certificates in the per-account + security settings dialog. + </para> + + </sect2> + <sect2 id="encryption-keygen"> <title>Making Encryption Keys</title> <para> |
