<para>
|
|
<function>openssl_pkcs7_verify</function> reads the S/MIME message
|
|
contained in the filename specified by <parameter>filename</parameter> and
|
|
examines the digital signature. It returns &true; if the signature is
|
|
verified, &false; if it is not correct (the message has been tampered with,
|
|
or the signing certificate is invalid), or -1 on error.
|
|
</para>
|
|
<para>
|
|
<parameter>flags</parameter> can be used to affect how the signature is
|
|
verified - see <link linkend="openssl.pkcs7.flags">PKCS7 constants</link>
|
|
for more information.
|
|
</para>
|
|
<para>
|
|
If the <parameter>outfilename</parameter> is specified, it should be a
|
|
string holding the name of a file into which the certificates of the
|
|
persons that signed the messages will be stored in PEM format.
|
|
</para>
|
|
<para>
|
|
If the <parameter>cainfo</parameter> is specified, it should hold
|
|
information about the trusted CA certificates to use in the verification
|
|
process - see <link linkend="openssl.cert.verification">certificate
|
|
verification</link> for more information about this parameter.
|
|
</para>
|
|
<para>
|
|
If the <parameter>extracerts</parameter> is specified, it is the filename
|
|
of a file containing a bunch of certificates to use as untrusted CAs.
