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. 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 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.
