| =head1 NAME
 | |
| 
 | |
| 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, X509_NAME *nm, int indent, unsigned long flags);
 | |
|  int X509_NAME_print_ex_fp(FILE *fp, X509_NAME *nm, int indent, unsigned long flags);
 | |
|  char *	X509_NAME_oneline(X509_NAME *a,char *buf,int size);
 | |
|  int X509_NAME_print(BIO *bp, 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>. At most B<size>
 | |
| bytes will be written. If B<buf> is B<NULL> then a buffer is dynamically allocated
 | |
| and returned, otherwise 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() are legacy functions which
 | |
| 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.
 | |
| 
 | |
| 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)|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.
