12 int X509_NAME_print_ex(BIO *out, X509_NAME *nm, int indent, unsigned long flags);

19 X509_NAME_print_ex() prints a human readable version of B<nm> to BIO B<out>. Each
20 line (for multiline formats) is indented by B<indent> spaces. The output format
21 can be extensively customised by use of the B<flags> parameter.
23 X509_NAME_print_ex_fp() is identical to X509_NAME_print_ex() except the output is
24 written to FILE pointer B<fp>.
26 X509_NAME_oneline() prints an ASCII version of B<a> to B<buf>. At most B<size>
27 bytes will be written. If B<buf> is B<NULL> then a buffer is dynamically allocated
28 and returned, otherwise B<buf> is returned.
30 X509_NAME_print() prints out B<name> to B<bp> indenting each line by B<obase>
31 characters. Multiple lines are used if the output (including indent) exceeds
36 The functions X509_NAME_oneline() and X509_NAME_print() are legacy functions which
37 produce a non standard output form, they don't handle multi character fields and
38 have various quirks and inconsistencies. Their use is strongly discouraged in new
41 Although there are a large number of possible flags for most purposes
42 B<XN_FLAG_ONELINE>, B<XN_FLAG_MULTILINE> or B<XN_FLAG_RFC2253> will suffice.
43 As noted on the L<ASN1_STRING_print_ex(3)|ASN1_STRING_print_ex(3)> manual page
44 for UTF8 terminals the B<ASN1_STRFLGS_ESC_MSB> should be unset: so for example
45 B<XN_FLAG_ONELINE & ~ASN1_STRFLGS_ESC_MSB> would be used.
47 The complete set of the flags supported by X509_NAME_print_ex() is listed below.
49 Several options can be ored together.
51 The options B<XN_FLAG_SEP_COMMA_PLUS>, B<XN_FLAG_SEP_CPLUS_SPC>,
52 B<XN_FLAG_SEP_SPLUS_SPC> and B<XN_FLAG_SEP_MULTILINE> determine the field separators
53 to use. Two distinct separators are used between distinct RelativeDistinguishedName
54 components and separate values in the same RDN for a multi-valued RDN. Multi-valued
55 RDNs are currently very rare so the second separator will hardly ever be used.
57 B<XN_FLAG_SEP_COMMA_PLUS> uses comma and plus as separators. B<XN_FLAG_SEP_CPLUS_SPC>
58 uses comma and plus with spaces: this is more readable that plain comma and plus.
59 B<XN_FLAG_SEP_SPLUS_SPC> uses spaced semicolon and plus. B<XN_FLAG_SEP_MULTILINE> uses
60 spaced newline and plus respectively.
62 If B<XN_FLAG_DN_REV> is set the whole DN is printed in reversed order.
64 The fields B<XN_FLAG_FN_SN>, B<XN_FLAG_FN_LN>, B<XN_FLAG_FN_OID>,
65 B<XN_FLAG_FN_NONE> determine how a field name is displayed. It will
66 use the short name (e.g. CN) the long name (e.g. commonName) always
67 use OID numerical form (normally OIDs are only used if the field name is not
68 recognised) and no field name respectively.
70 If B<XN_FLAG_SPC_EQ> is set then spaces will be placed around the '=' character
71 separating field names and values.
73 If B<XN_FLAG_DUMP_UNKNOWN_FIELDS> is set then the encoding of unknown fields is
74 printed instead of the values.
76 If B<XN_FLAG_FN_ALIGN> is set then field names are padded to 20 characters: this
77 is only of use for multiline format.
79 Additionally all the options supported by ASN1_STRING_print_ex() can be used to
80 control how each field value is displayed.
82 In addition a number options can be set for commonly used formats.
84 B<XN_FLAG_RFC2253> sets options which produce an output compatible with RFC2253 it
86 B<ASN1_STRFLGS_RFC2253 | XN_FLAG_SEP_COMMA_PLUS | XN_FLAG_DN_REV | XN_FLAG_FN_SN | XN_FLAG_DUMP_UNKNOWN_FIELDS>
89 B<XN_FLAG_ONELINE> is a more readable one line format which is the same as:
90 B<ASN1_STRFLGS_RFC2253 | ASN1_STRFLGS_ESC_QUOTE | XN_FLAG_SEP_CPLUS_SPC | XN_FLAG_SPC_EQ | XN_FLAG_FN_SN>
92 B<XN_FLAG_MULTILINE> is a multiline format which is the same as:
93 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>
95 B<XN_FLAG_COMPAT> uses a format identical to X509_NAME_print(): in fact it calls X509_NAME_print() internally.
