=head1 NAME
|
|
|
|
X509V3_EXT_print, X509V3_EXT_print_fp - pretty print X509 certificate extensions
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/x509v3.h>
|
|
|
|
int X509V3_EXT_print(BIO *out, X509_EXTENSION *ext, unsigned long flag, int indent);
|
|
int X509V3_EXT_print_fp(FILE *out, X509_EXTENSION *ext, int flag, int indent);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
X509V3_EXT_print() and X509V3_EXT_print_fp() parse and print the extension
|
|
info from I<ext> to I<bio> or I<out> with indentation set via I<indent>.
|
|
I<flag> determines the behaviour if an extension could not be parsed and can be
|
|
one of:
|
|
B<X509V3_EXT_DEFAULT> (equivalent to 0): an unknown or unparsable extension
|
|
stops the parsing and the function returns a failure.
|
|
B<X509V3_EXT_PARSE_UNKNOWN>: an unknown or unparsable extension is handled by
|
|
printing it through the B<ASN1_parse_dump()> function, and the function returns
|
|
success.
|
|
B<X509V3_EXT_DUMP_UNKNOWN>: an unknown or unparsable extension is handled by
|
|
printing it through the B<BIO_dump_indent()> function, and the function returns
|
|
success,
|
|
B<X509V3_EXT_ERROR_UNKNOWN>: an unknown or unparsable extension is handled by
|
|
printing either "<Not Supported>" or "<Parse Error>", and the function returns
|
|
success.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
X509V3_EXT_print() and X509V3_EXT_print_fp() return 1 for success and 0 for
|
|
failure.
