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 custom-
     ised 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. At
     most size bytes will be written. If buf is NULL then a
     buffer is dynamically allocated and returned, otherwise 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 respec-
     tively.

     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. com-
     monName) 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 compa-
     tible 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 it 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 is 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.
