.. \*(C` and \*(C' are quotes in nroff, nothing in troff, for use with C<>.
. ds C` "" . ds C' "" 'br\} . ds C` . ds C' 'br\}
Escape single quotes in literal strings from groff's Unicode transform.

If the F register is >0, we'll generate index entries on stderr for
titles (.TH), headers (.SH), subsections (.SS), items (.Ip), and index
entries marked with X<> in POD. Of course, you'll have to process the
output yourself in some meaningful fashion.

Avoid warning from groff about undefined register 'F'.

Title "X509_ACERT_print_ex 3" For nroff, turn off justification. Always turn off hyphenation; it makes
way too many mistakes in technical documents.
.nh X509_ACERT_print_ex, X509_ACERT_print \- X509_ACERT printing routines Header "SYNOPSIS" .Vb 1 #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); .Ve Header "DESCRIPTION" \fBX509_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) .Sp = item * .Sp 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) .Sp = item * .Sp The serial number of the attribute certificate (X509_FLAG_NO_SERIAL) .Sp = item * .Sp 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\*(Aqs certificate are displayed. (X509_FLAG_NO_SUBJECT) .Sp = item * .Sp The name of the attribute certificate issuer as returned from \fBX509_ACERT_get0_issuerName() and printed using X509_NAME_print_ex(). (X509_FLAG_NO_ISSUER) .Sp = item * .Sp 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) .Sp = item * .Sp 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) .Sp = item * .Sp All X.509 extensions contained in the attribute certificate. (X509_FLAG_NO_EXTENSIONS) .Sp = item * .Sp The signature is printed with X509_signature_print(). (X509_FLAG_NO_SIGDUMP) .Sp If cflag is specifies as X509_FLAG_COMPAT, all of the above data in the attribute certificate will be printed. .Sp The nmflags flag determines the format used to output all fields printed using \fBX509_NAME_print_ex(). See X509_NAME_print_ex\|(3) for details. .Sp \fBX509_ACERT_print() is equivalent to calling X509_ACERT_print_ex() with the \fInmflags and cflags set to XN_FLAG_COMPAT and X509_FLAG_COMPAT respectively. Header "RETURN VALUES" \fBX509_ACERT_print_ex() X509_ACERT_print() return 1 for success and 0 for failure. Header "SEE ALSO" \fBX509_NAME_print_ex\|(3) Header "HISTORY" \fBX509_ACERT_print() and X509_ACERT_print_ex() were added in OpenSSL 3.4.
