AI Summary: The task is to modify the curl library's handling of invalid certificates within the system's certificate store when using the `--ca-native` or `CURLSSLOPT_NATIVE_CA` options. Specifically, the library should be updated to gracefully ignore invalid certificates that do not affect the successful completion of a TLS connection, preventing errors like "error:068000DD:asn1 encoding routines::illegal padding" caused by such certificates. This requires careful consideration to avoid compromising security while improving compatibility.
