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. 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 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.
