There could be a function to PAUSE the file hash. While downloading torrents it keeps hashing non-stop. The only solution I found was to use a temporary directory in torrents, but I don't like this solution. It would be interesting to implement this function.

Fopnu is not a torrent client, it uses its own protocol. I still think that like tixati it should always check the hashes of files after the download has completed, preferably with SHA3-512. Likewise in today's internet powerful encryption is a must, I think that Grand Cru-128, AES-256, Anubis-320, Kalyna-512 and Threefish-1024 are secure. For asymmetric encryption I recommend the use of Kyber-1024 alongside RSA-4096, I do not trust elliptic curve cryptography. For digital signatures I recommend Dilithium5 combined with RSA-PSS-4096.
