About SHA-256
SHA-256 produces a 256-bit (64 hex character) hash and belongs to the SHA-2 family. It is the workhorse of modern security: TLS certificates, software checksums, Bitcoin and most integrity checks use it. No practical attacks are known.
The hash is computed from your text exactly as typed (encoded as UTF-8), including spaces and line breaks. A single extra space gives a completely different result, which is the usual reason hashes “don’t match” between tools. Turn on “Hash each line separately” to process a list.

Frequently asked questions
How long is a SHA-256 hash?
256 bits, written as 64 hexadecimal characters.
Can I reverse an SHA-256 hash?
No. Hash functions are one-way. Short or common inputs can be found by guessing, which is why passwords should use dedicated slow hashes such as bcrypt or Argon2.
Is my text sent to a server?
No. The hash is calculated in your browser.
