Frequently Asked Questions
SHA-256 is a SHA-2 family hash function that returns a fixed 256-bit digest, commonly written as 64 hexadecimal characters.
Use a dedicated password-hashing algorithm such as Bcrypt or Argon2 for passwords. SHA-256 alone is not a password storage solution.
Yes. The identical sequence of characters produces the same SHA-256 hash.
No. Hashing is one-way, though weak input values can still be guessed.
SHA-256 produces 256 bits. Representing those bits in hexadecimal requires 64 characters.
No. SHA-256 calculation happens entirely in your browser.
