Regarding compliance with encryption specification recommended by Japan e-government and similar encryption algorithm,  we cannot answer clearly due to securement of security although encryption of HULFT is unique logic.

By the way, 'HULFT8 CipherOption(AES)' (*1) that is one of the HULFT options complies with encryption specification recommended by Japan e-government, and utilizes AES encryption that has passed the CAVP test by NIST.

As following above, if you utilize the encryption recommended by e-government, 'HULFT CipherOption (AES)' (*1) is preferred.

And 'HULFT Cipher Option (C4S)' (*4) that uses chaos function for the purpose of strongly secured common encryption method, is also useful.

(*1)
Official name in version 7 is 'HULFT7 encryption option (AES)', and its of version 6 doesn't support it.

(*2)
It stands for National Institute of Standards and Technology, which is governed by CAA.

(*3)
It stands for Cryptographic Algorithm Validation Program.
It is the institution that takes on the compliance test and authorization against algorithm regulated by NIST in USA.

(*4)
Official name in version 7 is 'HULFT7 encryption option (C4S)', and its in version 6 is 'HULFT encryption option'.
