=head1 SYNOPSIS
|
|
|
|
#include <openssl/x509.h>
|
|
|
|
X509 *d2i_X509_AUX(X509 **px, const unsigned char **in, long len);
|
|
int i2d_X509_AUX(X509 *x, unsigned char **out);
|
|
int i2d_re_X509_tbs(X509 *x, unsigned char **out);
|
|
int i2d_re_X509_CRL_tbs(X509_CRL *crl, unsigned char **pp);
|
|
int i2d_re_X509_REQ_tbs(X509_REQ *req, unsigned char **pp);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
The X509 encode and decode routines encode and parse an
|
|
B<X509> structure, which represents an X509 certificate.
|
|
|
|
d2i_X509_AUX() is similar to L<d2i_X509(3)> but the input is expected to
|
|
consist of an X509 certificate followed by auxiliary trust information.
|
|
This is used by the PEM routines to read "TRUSTED CERTIFICATE" objects.
|
|
This function should not be called on untrusted input.
|
|
|
|
i2d_X509_AUX() is similar to L<i2d_X509(3)>, but the encoded output
|
|
contains both the certificate and any auxiliary trust information.
|
|
This is used by the PEM routines to write "TRUSTED CERTIFICATE" objects.
|
|
Note that this is a non-standard OpenSSL-specific data format.
|
|
|
|
i2d_re_X509_tbs() is similar to L<i2d_X509(3)> except it encodes only
|
|
the TBSCertificate portion of the certificate. i2d_re_X509_CRL_tbs()
|
|
and i2d_re_X509_REQ_tbs() are analogous for CRL and certificate request,
|
|
respectively. The "re" in B<i2d_re_X509_tbs> stands for "re-encode",
|
|
and ensures that a fresh encoding is generated in case the object has been
|
|
modified after creation (see the BUGS section).
|
|
|
|
The encoding of the TBSCertificate portion of a certificate is cached
|
|
in the B<X509> structure internally to improve encoding performance
|
|
and to ensure certificate signatures are verified correctly in some
|
|
certificates with broken (non-DER) encodings.
|
|
|
|
If, after modification, the B<X509> object is re-signed with X509_sign(),
|
|
the encoding is automatically renewed. Otherwise, the encoding of the
|
|
TBSCertificate portion of the B<X509> can be manually renewed by calling
|
|
i2d_re_X509_tbs().
