26 | a trusted agent called a Certificate Authority (CA). The certificates

74 | <para>The <application>make-ca.sh</application> script will download a set
|
---|
75 | of certificates from one of five projects (aurora, beta, central, nss, or
|
---|
76 | release) in the Mozialla version control system. It defaults to the release
|
---|
77 | branch, which is identical to the version that ships with the Mozilla
|
---|
78 | products in this book. If you'd like to change the branch that is retrieved,
|
---|
79 | edit the file and set <envar>CERTSOURCE</envar> to one of the five values
|
---|
80 | above.</para>
|
---|
81 |
|
---|
82 | <para>Additionally, any local certificates stored in
|
---|
83 | <filename>/etc/ssl/local</filename> will be copied into both the single-file
|
---|
84 | <filename>/etc/ssl/ca-bundle.crt</filename> (used by programs that link to
|
---|
85 | <application>gnutls</application>), and into the certificate store directory
|
---|
86 | <filename>/etc/ssl/certs</filename> (used by programs that link to
|
---|
87 | <application>OpenSSL</application>). All certificates will pass a date and
|
---|
88 | trust validation, and any existing certificates in
|
---|
89 | <filename>/etc/ssl/ca-bundle.crt</filename> or
|
---|
90 | <filename>/etc/ssl/certs</filename> will be removed upon successful
|
---|
91 | completion of this script.</para>

---|
92 |
|
---|
93 | <para>Finally, if you've installed <xref linkend="java"/> or <xref
