=head1 NAME

|
|
|
||
|
|
x509v3_cache_extensions
|
||
|
|
- cache info on various X.509v3 extensions and further derived certificate data
|
||
|
|
|
||
|
|
=head1 SYNOPSIS
|
||
|
|
|
||
|
|
#include <openssl/x509v3.h>
|
||
|
|
|
||
|
|
int x509v3_cache_extensions(X509 *x, OSSL_LIB_CTX *libctx, const char *propq);
|
||
|
|
|
||
|
|
=head1 DESCRIPTION
|
||
|
|
|
||
|
|
This function processes any X509v3 extensions present in an X509 object I<x>
|
||
|
|
and caches the result of that processing as well as further derived info,
|
||
|
|
for instance whether the certificate is self-issued or has version X.509v1.
|
||
|
|
It computes the SHA1 digest of the certificate using the default library context
|
||
|
|
and property query string and stores the result in x->sha1_hash,
|
||
|
|
or on failure sets B<EXFLAG_NO_FINGERPRINT> in x->flags.
|
||
|
|
It sets B<X509_SIG_INFO_VALID> in x->flags if x->siginf was filled successfully,
|
||
|
|
which may not be possible if a referenced algorithm is unknown or not available.
|
||
|
|
Many OpenSSL functions that use an X509 object call this function implicitly.
|
||
|
|
|
||
|
|
=head1 RETURN VALUES
|
||
|
|
|
||
|
|
This function returns 0 if the extensions or other portions of the certificate
|
||
|
|
are invalid or an error occurred.
|
||
|
|
Otherwise it returns 1.
