What is SHA-256?
SHA-256 deterministically maps input bytes to a fixed digest. The same text and character encoding produce the same value every time.

How to hash text with SHA-256
Enter text, select its character encoding, and copy the digest generated automatically. No submit step or network upload is required.
Encoding and security considerations
Character encoding changes the input bytes and therefore the digest. Hashing is one-way and is not encryption; use a modern password-hashing scheme for password storage.
Frequently asked questions
SHA-256 output is deterministic and cannot be decrypted. SHA-512 produces a longer digest than SHA-256, while MD5 and SHA-1 should be reserved for legacy compatibility.
