The ARIA is used as the standard cipher algorithm in South Korea.
Therefore the government and companies who want to work with the
government should use this algorithm.
The specific usecase is the e-government standard framework[1] in South
Korea, which is a standard framework that helps to develop software for
the government, It uses ARIA cipher.

Also, the OpenSSL already supports ARIA cipher for TLS so I think we can
use ARIA-kTLS with a simple PR.

I think these are good usecases.
This is not just an idea/thesis without usecases.
