Question 1

What hash algorithms are supported?

Accepted Answer

FreeDevKit supports MD5, SHA-1, SHA-256, and SHA-512. SHA variants use the Web Crypto API for accurate results. MD5 uses a pure JavaScript implementation.

Question 2

Is my data safe when generating hashes?

Accepted Answer

Yes. All hashing happens entirely in your browser using JavaScript. Your text is never sent to any server.

Question 3

What is the difference between MD5 and SHA-256?

Accepted Answer

MD5 produces a 128-bit hash and is fast but considered insecure for cryptographic purposes. SHA-256 produces a 256-bit hash and is widely used for security applications.

Question 4

Can I compare two hashes?

Accepted Answer

Yes. Switch to Compare mode, paste two hashes, and click Compare. The tool checks if they match (case-insensitive comparison).

Question 5

Are hashes reversible?

Accepted Answer

No. Hash functions are one-way — you cannot recover the original text from a hash. This is what makes them useful for password storage and integrity checks.
