.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The X509 encode and decode routines encode and parse an
\&\fBX509\fR structure, which represents an X509 certificate.
.PP
\&\fBd2i_X509_AUX()\fR is similar to \fBd2i_X509\fR\|(3) but the input is expected to
consist of an X509 certificate followed by auxiliary trust information.
This is used by the \s-1PEM\s0 routines to read \*(L"\s-1TRUSTED CERTIFICATE\*(R"\s0 objects.
This function should not be called on untrusted input.
.PP
\&\fBi2d_X509_AUX()\fR is similar to \fBi2d_X509\fR\|(3), but the encoded output
contains both the certificate and any auxiliary trust information.
This is used by the \s-1PEM\s0 routines to write \*(L"\s-1TRUSTED CERTIFICATE\*(R"\s0 objects.
Note that this is a non-standard OpenSSL-specific data format.
.PP
\&\fBi2d_re_X509_tbs()\fR is similar to \fBi2d_X509\fR\|(3) except it encodes only
the TBSCertificate portion of the certificate.  \fBi2d_re_X509_CRL_tbs()\fR
and \fBi2d_re_X509_REQ_tbs()\fR are analogous for \s-1CRL\s0 and certificate request,
respectively.  The \*(L"re\*(R" in \fBi2d_re_X509_tbs\fR stands for \*(L"re-encode\*(R",
and ensures that a fresh encoding is generated in case the object has been
modified after creation (see the \s-1BUGS\s0 section).
.PP
The encoding of the TBSCertificate portion of a certificate is cached
in the \fBX509\fR structure internally to improve encoding performance
and to ensure certificate signatures are verified correctly in some
certificates with broken (non-DER) encodings.
.PP
If, after modification, the \fBX509\fR object is re-signed with \fBX509_sign()\fR,
the encoding is automatically renewed. Otherwise, the encoding of the
TBSCertificate portion of the \fBX509\fR can be manually renewed by calling
\&\fBi2d_re_X509_tbs()\fR.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
\&\fBd2i_X509_AUX()\fR returns a valid \fBX509\fR structure or \s-1NULL\s0 if an error occurred.
.PP
\&\fBi2d_X509_AUX()\fR returns the length of encoded data or \-1 on error.
.PP
\&\fBi2d_re_X509_tbs()\fR, \fBi2d_re_X509_CRL_tbs()\fR and \fBi2d_re_X509_REQ_tbs()\fR return the
length of encoded data or <=0 on error.
