Use these to check a download or compare two values. Never store passwords as a plain SHA digest: use bcrypt or Argon2, which PHP's password_hash() gives you.

About this tool
Method, assumptions, practical next steps, and limits.
Matching another tool's output
A digest changes completely if one byte changes. When this tool and sha256sum disagree, the cause is almost always a trailing newline: echo "text" | sha256sum hashes the newline too, while printf "text" | sha256sum does not.
Not for passwords
SHA-256 is designed to be fast, which is exactly wrong for passwords: an attacker can try billions of guesses a second. Store passwords with a slow, salted algorithm such as bcrypt or Argon2id. In PHP that is password_hash(), and in Laravel the Hash facade.
Why no MD5?
Web Crypto does not offer MD5, and it should not be used for anything security-related; collisions can be produced on a laptop.
