◆ botan_x509_cert_verify()

int botan_x509_cert_verify ( int * validation_result,
botan_x509_cert_t cert,
const botan_x509_cert_t * intermediates,
size_t intermediates_len,
const botan_x509_cert_t * trusted,
size_t trusted_len,
const char * trusted_path,
size_t required_strength,
const char * hostname,
uint64_t reference_time )

Returns 0 if the validation was successful, 1 if validation failed, and negative on error. A status code with details is written to *validation_result

Intermediates or trusted lists can be null Trusted path can be null
