Question 1

Which hashing algorithm should I use?

Accepted Answer

For general security, digital signatures, and database verification, SHA-256 or SHA-512 are highly recommended over legacy SHA-1.

Question 2

Is hashing the same as encryption?

Accepted Answer

No. Hashing is a one-way mathematical function to verify integrity. It cannot be decoded back into plain text, unlike two-way encryption.

Question 3

Which hash algorithms are supported?

Accepted Answer

SHA-1, SHA-256, SHA-384, and SHA-512 via your browser's native WebCrypto engine — no libraries, no network calls, and digests appear as soon as you type or drop a file.

Question 4

Can I hash a file instead of text?

Accepted Answer

Yes. Load a file and its digest is computed locally, which is handy for verifying downloads match a published checksum before trusting them.

Question 5

Which algorithm should I pick for integrity checks?

Accepted Answer

SHA-256 is the current general-purpose default. SHA-1 remains available for legacy verification only and shouldn't be used where collision resistance matters.
