Frequently Asked Questions
Can SHA-256 hashes be reversed?
No. SHA-256 is designed as a one-way function, although weak input values can still be guessed through brute force.
Can SHA-256 be used for passwords?
Not by itself. Passwords should use a dedicated password hashing algorithm such as Argon2id, scrypt, bcrypt or PBKDF2.
