Passwords for new accounts
Password generator draws from the browser's secure random source and shows the strength of each password in bits. The default 16 characters with symbols comes out at a little over 100 bits.
Checking a download
Software vendors publish a SHA-256 checksum next to the installer. Hash computes it for a file of any size and compares it with the one you paste, so a damaged or altered download shows up before anyone installs it.
Files that have to travel as text
Some places accept only text, such as an e-mail body or a JSON field. Base64 turns a file or image into text and back, with a URL-safe option for links.
Confidential files
A hash recorded today proves later that a contract has not been changed. The file is read on your own computer, so it can stay confidential.
