Signing documents with software certificates is not a perfectly secure method. Numerous ways are possible to circumvent the security features.</paragraph> -<paragraph role="paragraph" id="par_id7953123" xml-lang="en-US" l10n="NEW">Example: Think about someone wants to camouflage his identity to be a sender from your bank. He can easily get a certificate using a false name, then send you any signed e-mail pretending he is working for your bank. You will get that e-mail, and the e-mail or the document within has the "valid signed" icon. </paragraph> -<paragraph role="paragraph" id="par_id6195257" xml-lang="en-US" l10n="NEW">Do not trust the icon.

On Solaris and Linux systems, files that are supplied by Thunderbird, Mozilla or Firefox are used. You must ensure that the files that are in use within your system are really the original files that were supplied by the original developers. For malevolent intruders, there are numerous ways to replace original files with other files that they supply.</paragraph> -<paragraph role="warning" id="par_id6819971" xml-lang="en-US" l10n="NEW">The messages about validation of a signature that you see in %PRODUCTNAME are the messages that the validation files return. The %PRODUCTNAME software has no way to ensure that the messages reflect the true status of any certificate. The %PRODUCTNAME software only displays the messages that other files that are not under control of %PRODUCTNAME report. There is no legal responsibility of %PRODUCTNAME that the displayed messages reflect the true status of a digital signature.</paragraph> -<paragraph role="heading" id="par_idN1063C" xml-lang="en-US" level="2" l10n="NEW">Get a certificate</paragraph> +<paragraph role="heading" id="par_idN1063C" xml-lang="en-US" level="3" l10n="NEW">Get a certificate</paragraph> <paragraph role="paragraph" id="par_idN10640" xml-lang="en-US" l10n="NEW">You can get a certificate from a certification authority, which may be a private company or a governmental institution.
