X509_NAME_print_ex, X509_NAME_print_ex_fp, X509_NAME_print,
|
|
X509_NAME_oneline - X509_NAME printing routines
|

=head1 SYNOPSIS
|
|
|
|
#include <openssl/x509.h>
|
|
|
|
int X509_NAME_print_ex(BIO *out, const X509_NAME *nm, int indent, unsigned long flags);
|
|
int X509_NAME_print_ex_fp(FILE *fp, const X509_NAME *nm, int indent, unsigned long flags);
|
|
char *X509_NAME_oneline(const X509_NAME *a, char *buf, int size);
|
|
int X509_NAME_print(BIO *bp, const X509_NAME *name, int obase);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
X509_NAME_print_ex() prints a human readable version of B<nm> to BIO B<out>. Each
|
|
line (for multiline formats) is indented by B<indent> spaces. The output format
|
|
can be extensively customised by use of the B<flags> parameter.
|
|
|
|
X509_NAME_print_ex_fp() is identical to X509_NAME_print_ex() except the output is
|
|
written to FILE pointer B<fp>.
|
|
|
|
X509_NAME_oneline() prints an ASCII version of B<a> to B<buf>.
|
|
If B<buf> is B<NULL> then a buffer is dynamically allocated and returned, and
|
|
B<size> is ignored.
|
|
Otherwise, at most B<size> bytes will be written, including the ending '\0',
|
|
and B<buf> is returned.
|
|
|
|
X509_NAME_print() prints out B<name> to B<bp> indenting each line by B<obase>
|
|
characters. Multiple lines are used if the output (including indent) exceeds
|
|
80 characters.
|
|
|
|
=head1 NOTES
|
|
|
|
The functions X509_NAME_oneline() and X509_NAME_print()
|
|
produce a non standard output form, they don't handle multi character fields and
|
|
have various quirks and inconsistencies.
|
|
Their use is strongly discouraged in new applications and they could
|
|
be deprecated in a future release.
|
|
|
|
Although there are a large number of possible flags for most purposes
|
|
B<XN_FLAG_ONELINE>, B<XN_FLAG_MULTILINE> or B<XN_FLAG_RFC2253> will suffice.
|
|
As noted on the L<ASN1_STRING_print_ex(3)> manual page
|
|
for UTF8 terminals the B<ASN1_STRFLGS_ESC_MSB> should be unset: so for example
|
|
B<XN_FLAG_ONELINE & ~ASN1_STRFLGS_ESC_MSB> would be used.
|
|
|
|
The complete set of the flags supported by X509_NAME_print_ex() is listed below.
|
|
|
|
Several options can be ored together.
|
|
|
|
The options B<XN_FLAG_SEP_COMMA_PLUS>, B<XN_FLAG_SEP_CPLUS_SPC>,
|
|
B<XN_FLAG_SEP_SPLUS_SPC> and B<XN_FLAG_SEP_MULTILINE> determine the field separators
|
|
to use. Two distinct separators are used between distinct RelativeDistinguishedName
|
|
components and separate values in the same RDN for a multi-valued RDN. Multi-valued
|
|
RDNs are currently very rare so the second separator will hardly ever be used.
|
|
|
|
B<XN_FLAG_SEP_COMMA_PLUS> uses comma and plus as separators. B<XN_FLAG_SEP_CPLUS_SPC>
|
|
uses comma and plus with spaces: this is more readable that plain comma and plus.
|
|
B<XN_FLAG_SEP_SPLUS_SPC> uses spaced semicolon and plus. B<XN_FLAG_SEP_MULTILINE> uses
|
|
spaced newline and plus respectively.
|
|
|
|
If B<XN_FLAG_DN_REV> is set the whole DN is printed in reversed order.
|
|
|
|
The fields B<XN_FLAG_FN_SN>, B<XN_FLAG_FN_LN>, B<XN_FLAG_FN_OID>,
|
|
B<XN_FLAG_FN_NONE> determine how a field name is displayed. It will
|
|
use the short name (e.g. CN) the long name (e.g. commonName) always
|
|
use OID numerical form (normally OIDs are only used if the field name is not
|
|
recognised) and no field name respectively.
|
|
|
|
If B<XN_FLAG_SPC_EQ> is set then spaces will be placed around the '=' character
|
|
separating field names and values.
|
|
|
|
If B<XN_FLAG_DUMP_UNKNOWN_FIELDS> is set then the encoding of unknown fields is
|
|
printed instead of the values.
|
|
|
|
If B<XN_FLAG_FN_ALIGN> is set then field names are padded to 20 characters: this
|
|
is only of use for multiline format.
|
|
|
|
Additionally all the options supported by ASN1_STRING_print_ex() can be used to
|
|
control how each field value is displayed.
|
|
|
|
In addition a number options can be set for commonly used formats.
|
|
|
|
B<XN_FLAG_RFC2253> sets options which produce an output compatible with RFC2253 it
|
|
is equivalent to:
|
|
B<ASN1_STRFLGS_RFC2253 | XN_FLAG_SEP_COMMA_PLUS | XN_FLAG_DN_REV | XN_FLAG_FN_SN | XN_FLAG_DUMP_UNKNOWN_FIELDS>
|
|
|
|
|
|
B<XN_FLAG_ONELINE> is a more readable one line format which is the same as:
|
|
B<ASN1_STRFLGS_RFC2253 | ASN1_STRFLGS_ESC_QUOTE | XN_FLAG_SEP_CPLUS_SPC | XN_FLAG_SPC_EQ | XN_FLAG_FN_SN>
|
|
|
|
B<XN_FLAG_MULTILINE> is a multiline format which is the same as:
|
|
B<ASN1_STRFLGS_ESC_CTRL | ASN1_STRFLGS_ESC_MSB | XN_FLAG_SEP_MULTILINE | XN_FLAG_SPC_EQ | XN_FLAG_FN_LN | XN_FLAG_FN_ALIGN>
|
|
|
|
B<XN_FLAG_COMPAT> uses a format identical to X509_NAME_print(): in fact it calls X509_NAME_print() internally.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
X509_NAME_oneline() returns a valid string on success or NULL on error.
|
|
|
|
X509_NAME_print() returns 1 on success or 0 on error.
|
|
|
|
X509_NAME_print_ex() and X509_NAME_print_ex_fp() return 1 on success or 0 on error
|
|
if the B<XN_FLAG_COMPAT> is set, which is the same as X509_NAME_print(). Otherwise,
|
|
it returns -1 on error or other values on success.
