Frequently asked questions
Can a hash be reversed?
Cryptographic hashes are one-way functions and are not designed to be decoded.
Which algorithm should I choose?
SHA-256 is a strong general default. SHA-384 and SHA-512 provide longer digests.
Is this suitable for storing passwords?
No. Password storage should use a dedicated, salted password hashing function such as Argon2 or scrypt.
