It's technically not 'encryption', because there is no decryption. However, for things like passwords, it's what is used to obfuscate the data. It's also used to make, essentially, a unique identifier to software. Each instance of the same software will create the same hash, so you can see if one instance is different from the original. This is commonly used on software-download websites so you can be sure that the software you get is the same as what they intended to host. I'm assuming that's what you mean by "determining whether something is true or not". You’re half correct. It’s technically not ‘encryption’, because there is no decryption.
