3.5.0                                              2025-06-04                          X509_ACERT_PRINT_EX(3SSL)

X509_ACERT_print_ex() prints a human readable version of the attribute certificate acert to BIO bp.

       The following data contained in the attribute certificate is printed in order:

       •   The header text "Attribute certificate:" and "Data:" (X509_FLAG_NO_HEADER)

           = item *

           The  attribute  certificate version number as defined by the standard, followed in parentheses by the
           value contained in the version field in hexadecimal notation.  If the version number is not  a  valid
           value  according  to the specification, only the raw value is printed.  See X509_ACERT_get_version(3)
           for details. (X509_FLAG_NO_VERSION)

           = item *

           The serial number of the attribute certificate (X509_FLAG_NO_SERIAL)

           = item *

           The identity of the holder of the attribute certificate. If the holder issuer name  is  present,  the
           first  GENERAL_NAME  returned  by  X509_ACERT_get0_holder_entityName()  is  printed.   If  the holder
           baseCertificateId is present, the issuer name (printed with X509_NAME_print_ex) and serial number  of
           the holder's certificate are displayed. (X509_FLAG_NO_SUBJECT)

           = item *

           The  name  of  the  attribute  certificate  issuer  as returned from X509_ACERT_get0_issuerName() and
           printed using X509_NAME_print_ex().  (X509_FLAG_NO_ISSUER)

           = item *

           The  period  of  validity  between  the   times   returned   from   X509_ACERT_get0_notBefore()   and
           X509_ACERT_get0_notAfter().     The    values    are   printed   as   a   generalized   times   using
           ASN1_GENERALIZEDTIME_print(). (X509_FLAG_NO_VALIDITY)

           = item *

           The list of attributes contained in the attribute certificate.  The attribute type  is  printed  with
           i2a_ASN1_OBJECT().   String valued attributes are printed as raw string data. ASN1 encoded values are
           printed with ASN1_parse_dump().  (X509_FLAG_NO_ATTRIBUTES)

           = item *

           All X.509 extensions contained in the attribute certificate. (X509_FLAG_NO_EXTENSIONS)

           = item *

           The signature is printed with X509_signature_print(). (X509_FLAG_NO_SIGDUMP)

           If cflag is specifies as X509_FLAG_COMPAT, all of the above data in the attribute certificate will be
           printed.

           The nmflags flag determines the format used to output all fields printed using  X509_NAME_print_ex().
           See X509_NAME_print_ex(3) for details.

           X509_ACERT_print()  is equivalent to calling X509_ACERT_print_ex() with the nmflags and cflags set to
           XN_FLAG_COMPAT and X509_FLAG_COMPAT respectively.

X509_ACERT_print() and X509_ACERT_print_ex() were added in OpenSSL 3.4.
