No-throw api for AES128?

[Daniel Fricot]

Is there a no-throw api for AES128? Currently, I am using CryptoPP::StreamTransformationFilter for AES128 which may throw CryptoPP::InvalidCiphertext. This is not an error of course, it is expected behavior but our coding guidelines prefer no-throw api's. All throws (even catched throws) are logged in our application and we want to keep this to a minimum.

Thanks,

Daniel

You can use a cipher's StreamTransformation::ProcessString() directly rather than the StreamTransformationFilter.

The benchmarks use the same pattern. Also see
