mbedtls_x509_crt_verify_restartable() function

The certificate chain to be verified.

The list of trusted CAs.

The list of CRLs for trusted CAs.

The security profile to use for the verification.

The expected Common Name. This may be \c NULL if the CN need not be verified.

The address at which to store the result of the verification. If the verification couldn't be completed, the flag value is set to (uint32_t) -1.

The verification callback to use. See the documentation of mbedtls_x509_crt_verify() for more information.

The context to be passed to \p f_vrfy.

The restart context to use. This may be set to \c NULL to disable restartable ECC.

Unallocate all certificate data

Parse a single DER formatted certificate and add it to the end of the provided chained list.

Initialize a certificate (chain)

Parse a single DER formatted certificate and add it to the end of the provided chained list. This is a variant of mbedtls_x509_crt_parse_der() which takes temporary ownership of the CRT buffer until the CRT is destroyed.

Set the data required to verify peer certificate

Set own certificate chain and private key

Set own certificate and key for the current handshake

Set the data required to verify peer certificate for the current handshake

Verify a chain of certificates with respect to a configurable security profile.

Verify a chain of certificates. 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, mbedtls_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 (including invalid certificates) other than fatal error, as a non-zero return code immediately aborts the verification process. For fatal errors, a specific error code should be used (different from MBEDTLS_ERR_X509_CERT_VERIFY_FAILED which should not be returned at this point), or MBEDTLS_ERR_X509_FATAL_ERROR can be used if no better code is available.

Parse a single DER formatted certificate and add it to the end of the provided chained list.

Parse one DER-encoded or one or more concatenated PEM-encoded certificates and add them to the chained list. For CRTs in PEM encoding, the function parses permissively: if at least one certificate can be parsed, the function returns the number of certificates for which parsing failed (hence \c 0 if all certificates were parsed successfully). If no certificate could be parsed, the function returns the first (negative) error encountered during parsing. PEM encoded certificates may be interleaved by other data such as human readable descriptions of their content, as long as the certificates are enclosed in the PEM specific '-----{BEGIN/END} CERTIFICATE-----' delimiters.

Returns an informational string about the certificate.

Print a X.509 certificate structure to the debug output. This function is always used through the MBEDTLS_SSL_DEBUG_CRT() macro, which supplies the ssl context, file and line number parameters. \attention This function is intended for INTERNAL usage within the library only.
