X509_ACERT_PRINT_EX(3SSL) OpenSSL X509_ACERT_PRINT_EX(3SSL)
NAME
X509_ACERT_print_ex, X509_ACERT_print - X509_ACERT printing routines
SYNOPSIS
#include <openssl/x509_acert.h>
int X509_ACERT_print(BIO *bp, X509_ACERT *acert);
int X509_ACERT_print_ex(BIO *bp, X509_ACERT *acert, unsigned long nmflags,
unsigned long cflag);
DESCRIPTION
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.
RETURN VALUES
X509_ACERT_print_ex() X509_ACERT_print() return 1 for success and 0 for
failure.
