Question 1

What is the difference between MD5 and SHA-256?

Accepted Answer

MD5 produces a 128-bit hash and is fast but vulnerable to collisions. SHA-256 produces a 256-bit hash and is cryptographically secure, recommended for security use cases.

Question 2

Can I reverse a hash?

Accepted Answer

No. Hash functions are one-way — you cannot reverse a hash to get the original input. This is what makes them useful for password storage.

Question 3

Is this tool safe to use for passwords?

Accepted Answer

This tool runs in your browser and sends nothing to servers. However, for password storage, always use bcrypt or Argon2 instead of MD5/SHA-256.
