Frequently asked questions
Are hashes reversible?
A cryptographic hash is designed to be one-way. The same input always produces the same digest, but the digest does not directly reveal the input.
Should I use SHA-1?
SHA-1 has known collision weaknesses and is only included for legacy compatibility. Use SHA-256 or stronger for collision resistance.
Does a raw SHA-256 hash safely store passwords?
No. Password storage requires a dedicated password-hashing function such as Argon2id or scrypt with appropriate parameters and salts.
