Detailed Description

The X.509 module provides X.509 support which includes:

X.509 certificate (CRT) reading (see x509parse_crt() and x509parse_crtfile()).
X.509 certificate revocation list (CRL) reading (see x509parse_crl() andx509parse_crlfile()).
X.509 (RSA and ECC) private key reading (see x509parse_key() and x509parse_keyfile()).
X.509 certificate signature verification (see x509parse_verify())
X.509 certificate writing and certificate request writing (see x509write_crt_der() and x509write_csr_der()).

This module can be used to build a certificate authority (CA) chain and verify its signature. It is also used to generate Certificate Signing Requests and X509 certificates just as a CA would do.

	)

Verify the certificate signature.

            The verify callback is a user-supplied callback that
            can clear / modify / add flags for a certificate. If set,
            the verification callback is called for each
            certificate in the chain (from the trust-ca down to the
            presented crt). The parameters for the callback are:
            (void *parameter, x509_crt *crt, int certificate_depth,
            int *flags). With the flags representing current flags for
            that specific certificate and the certificate depth from
            the bottom (Peer cert depth = 0).

            All flags left after returning from the callback
            are also returned to the application. The function should
            return 0 for anything but a fatal error.

Parameters

crt	a certificate to be verified
trust_ca	the trusted CA chain
ca_crl	the CRL chain for trusted CA's
cn	expected Common Name (can be set to NULL if the CN must not be verified)
flags	result of the verification
f_vrfy	verification function
p_vrfy	verification parameter

Returns: 0 if successful or POLARSSL_ERR_X509_SIG_VERIFY_FAILED, in which case *flags will have one or more of the following values set: BADCERT_EXPIRED – BADCERT_REVOKED – BADCERT_CN_MISMATCH – BADCERT_NOT_TRUSTED or another error in case of a fatal error encountered during the verification process.
