Rename files to their hash digests.

Files downloaded from the internet often have useless names, and it is more effort than it is worth to give each file a meaningful name. To reduce duplicates, avoid quoting and spacing issues, and to keep things generally tidy in the laziest way possible, hashf allows you to quickly rename batches of files to the hash digests of their contents.

• supports MD5, SHA1, and SHA256 hashing algorithms
• allows you to change the destination directory of the rename
• allows you to copy as well as rename the files
