    PyCheck

    PyCheck

    Calculates the checksum of a file, and compares it to an original.

    PyCheck calculates the checksum of a file, and compares it to an original either by selecting an original copy of the file, or manually entering the checksum of the original file, such as when it is provided on a website from which you downloaded a file. In Linux this program depends on the Python3 TK package, so make sure you have python3-tk installed using your distribution's package manager before continuing. I digitally sign some files in my releases. If you'd like to verify those signatures, you can find my PGP/GPG keys at: https://marcusadams.me/keys.html If you'd like to donate there's several ways to do so: PayPal: https://paypal.me/gerowen Bitcoin (BTC): bc1q86c5j7wvf6cw78tf8x3szxy5gnxg4gj8mw4sy2 Monero (XMR): 42ho3m9tJsobZwQDsFTk92ENdWAYk2zL8Qp42m7pKmfWE7jzei7Fwrs87MMXUTCVifjZZiStt3E7c5tmYa9qNx
