X509_NAME_print_ex(3)        OpenSSL        X509_NAME_print_ex(3)

NAME

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

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);

DESCRIPTION

     X509_NAME_print_ex() prints a human readable version of nm
     to BIO out. Each line (for multiline formats) is indented by
     indent spaces. The output format can be extensively
     customised by use of the flags parameter.

     X509_NAME_print_ex_fp() is identical to X509_NAME_print_ex()
     except the output is written to FILE pointer fp.

     X509_NAME_oneline() prints an ASCII version of a to buf.  If
     buf is NULL then a buffer is dynamically allocated and
     returned, and size is ignored.  Otherwise, at most size
     bytes will be written, including the ending '\0', and buf is
     returned.

     X509_NAME_print() prints out name to bp indenting each line
     by obase characters. Multiple lines are used if the output
     (including indent) exceeds 80 characters.

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 XN_FLAG_ONELINE, XN_FLAG_MULTILINE or
     XN_FLAG_RFC2253 will suffice.  As noted on the
     ASN1_STRING_print_ex(3) manual page for UTF8 terminals the
     ASN1_STRFLGS_ESC_MSB should be unset: so for example
     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 XN_FLAG_SEP_COMMA_PLUS, XN_FLAG_SEP_CPLUS_SPC,
     XN_FLAG_SEP_SPLUS_SPC and 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.

     XN_FLAG_SEP_COMMA_PLUS uses comma and plus as separators.
     XN_FLAG_SEP_CPLUS_SPC uses comma and plus with spaces: this
     is more readable that plain comma and plus.
     XN_FLAG_SEP_SPLUS_SPC uses spaced semicolon and plus.
     XN_FLAG_SEP_MULTILINE uses spaced newline and plus
     respectively.

     If XN_FLAG_DN_REV is set the whole DN is printed in reversed
     order.

     The fields XN_FLAG_FN_SN, XN_FLAG_FN_LN, XN_FLAG_FN_OID,
     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 XN_FLAG_SPC_EQ is set then spaces will be placed around
     the '=' character separating field names and values.

     If XN_FLAG_DUMP_UNKNOWN_FIELDS is set then the encoding of
     unknown fields is printed instead of the values.

     If 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.

     XN_FLAG_RFC2253 sets options which produce an output
     compatible with RFC2253 it is equivalent to:
      ASN1_STRFLGS_RFC2253 | XN_FLAG_SEP_COMMA_PLUS |
     XN_FLAG_DN_REV | XN_FLAG_FN_SN | XN_FLAG_DUMP_UNKNOWN_FIELDS

     XN_FLAG_ONELINE is a more readable one line format which is
     the same as:
      ASN1_STRFLGS_RFC2253 | ASN1_STRFLGS_ESC_QUOTE |
     XN_FLAG_SEP_CPLUS_SPC | XN_FLAG_SPC_EQ | XN_FLAG_FN_SN

     XN_FLAG_MULTILINE is a multiline format which is the same
     as:
      ASN1_STRFLGS_ESC_CTRL | ASN1_STRFLGS_ESC_MSB |

     XN_FLAG_SEP_MULTILINE | XN_FLAG_SPC_EQ | XN_FLAG_FN_LN |
     XN_FLAG_FN_ALIGN

     XN_FLAG_COMPAT uses a format identical to X509_NAME_print():
     in fact it calls X509_NAME_print() internally.
