Frequently asked questions
Common questions about this tool.
SHA-256 is a widely used SHA-2 hash algorithm that produces a 256-bit digest.
It is common in digital signatures, certificate chains, checksums, and many API/security workflows.
SHA-256 output is 256 bits, typically shown as 64 hexadecimal characters.
Yes. SHA-256 is currently considered much stronger than MD5 and SHA-1 for integrity and collision resistance.
Not by itself. Password storage should use dedicated adaptive password hashing algorithms with salt and work factor.
That is the avalanche effect, a core property of cryptographic hashes.
In theory yes, but finding collisions is computationally infeasible with current practical methods.
No. It hashes exactly what you input; if you need salting, prepend/append your salt before hashing.
Yes. Compare the known SHA-256 checksum with the one you compute to verify integrity.
Yes. The hash is generated in your browser.
