Digest

Digest is a light-weight utility that calculates the digest (or "hash") of files or strings. With files, Digest provides an easy-to-use interface detailing basic file properties.

With strings, it provides an area for text input and editing as well as a variety of encoding settings. Both interfaces feature a list of all selected digests. Each digest is presented in both a hexadecimal and Base64, which can be copied to the pasteboard with a single click.
