X509_NAME printing routines
X509_NAME_print_ex(BIO *out, const X509_NAME *nm, int indent, unsigned long flags); int
X509_NAME_print_ex_fp(FILE *fp, const X509_NAME *nm, int indent, unsigned long flags); char *
X509_NAME_oneline(const X509_NAME *a, char *buf, int size); int
X509_NAME_print(BIO *bp, const X509_NAME *name, int obase);
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 the 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 NUL, 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. The functions
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_RFC2253will suffice. As noted on the ASN1_STRING_print_ex(3) manual page, for UTF-8 terminals the
ASN1_STRFLGS_ESC_MSBshould be unset: so for example
ASN1_STRFLGS_ESC_MSBwould be used. The complete set of the flags supported by
X509_NAME_print_exis listed below. Several options can be OR'ed together. The options
XN_FLAG_SEP_MULTILINEdetermine 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_PLUSuses comma and plus as separators.
XN_FLAG_SEP_CPLUS_SPCuses comma and plus with spaces: this is more readable that plain comma and plus.
XN_FLAG_SEP_SPLUS_SPCuses spaced semicolon and plus.
XN_FLAG_SEP_MULTILINEuses spaced newline and plus respectively. If
XN_FLAG_DN_REVis set, the whole DN is printed in reversed order. The fields
XN_FLAG_FN_NONEdetermine 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_EQis set, then spaces will be placed around the ‘
=’ character separating field names and values. If
XN_FLAG_DUMP_UNKNOWN_FIELDSis set, then the encoding of unknown fields is printed instead of the values. If
XN_FLAG_FN_ALIGNis 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(3) can be used to control how each field value is displayed. In addition a number of options can be set for commonly used formats.
XN_FLAG_RFC2253sets options which produce an output compatible with RFC 2253. It is equivalent to
XN_FLAG_ONELINEis a more readable one line format which is the same as:
XN_FLAG_MULTILINEis a multiline format which is the same as:
XN_FLAG_COMPATuses a format identical to
X509_NAME_print(): in fact it calls
X509_NAME_print_ex_fp() return 1 on success or 0 on error if
XN_FLAG_COMPATis set in flags. Otherwise, they return the number of printed bytes including the indentation or -1 on error.
X509_NAME_oneline() returns a valid string on success or
X509_NAME_print() returns 1 on success or 0 on error. ASN1_STRING_print_ex(3), d2i_X509_NAME(3), X509_NAME_get_index_by_NID(3), X509_NAME_new(3)
X509_NAME_print() first appeared in SSLeay 0.5.1 and have been available since OpenBSD 2.4.
X509_NAME_print_ex_fp() first appeared in OpenSSL 0.9.6 and have been available since OpenBSD 2.9.
