Checksum Thing 2.1.3

A menu bar application that watches a designated directory, such as your downloads folder, automatically recording and storing the checksum/digest values of arriving files. A simple context click displays the checksum value, another click conveniently copies that value to the clipboard. The checksum/digest algorithm used is selectable, supporting MD5, SHA1, and various others. Uses hardware accelerated cryptographic functions on supported macOS platforms. Optionally generates audible notifications to keep you informed.
