X509_VERIFY_CERT(3) FreeBSD Library Functions Manual X509_VERIFY_CERT(3)
NAME
X509_verify_cert - discover and verify X509 certificate chain
SYNOPSIS
#include <openssl/x509.h>
int
X509_verify_cert(X509_STORE_CTX *ctx);
DESCRIPTION
The X509_verify_cert() function attempts to discover and validate a
certificate chain based on parameters in ctx.
Applications rarely call this function directly, but it is used by
OpenSSL internally for certificate validation, in both the S/MIME and
SSL/TLS code.
RETURN VALUES
If a complete chain can be built and validated this function returns 1,
otherwise it returns a value <= 0 indicating failure.
Additional error information can be obtained by examining ctx, using
X509_STORE_CTX_get_error(3).
SEE ALSO

HISTORY
X509_verify_cert() first appeared in SSLeay 0.8.0 and has been available
since OpenBSD 2.4.
BUGS
This function uses the header <openssl/x509.h> as opposed to most chain
verification functions which use <openssl/x509_vfy.h>.
