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.

I fully agree that there should be a pause button/setting, its not only annoying how it insists on hashing files that are being written to like torrent downloads instead of waiting until its atleast idle, but also if you happen to missplace a larger file/folder and want to move it you cant until its finished hashing because "the file is in use by another program". Another nice setting related to this would be to be able to set a timer for how long it should wait after noticing a change before considering hashing files(in my opinion)
