[ghost]

Hi

I have installed "sudo apt install torrenttools" and then installed ISA-L Crypto from their github. does that mean i have torrenttools with ISA-L Crypto support? or am i still using openssl

The .deb packages are build with a static version of ISA-L Crypto. All ISA-l code is included in the executable and you do not need to install it separately. You can see the version of ISA-L that was used in the output of torrenttools --version.
The main hashing for torrent file creation will use ISA-L (SHA1 and SHA256), but if you use some other features like per-file checksums you will additionally use openssl as well, since not all algorithms are available in ISA-L.
