Context: The existing API `mbedtls_x509_parse_crt_der()` for parsing DER encoded X.509 CRTs unconditionally makes creates a copy of the input buffer in RAM. While this comes at the benefit of easy use, -- specifically: allowing the user to free or re-use the input buffer right after the call -- it creates a significant memory overhead, as the CRT is duplicated in memory (at least temporarily). This might not be tolerable a resource constrained device. As a remedy, this commit adds a new X.509 API call `mbedtls_x509_parse_crt_der_nocopy()` which has the same signature as `mbedtls_x509_parse_crt_der()` and almost the same semantics, with one difference: The input buffer must persist and be unmodified for the lifetime of the established instance of `mbedtls_x509_crt`, that is, until `mbedtls_x509_crt_free()` is called. |
