No — MD5 is broken for security purposes and vulnerable to collision attacks, so it shouldn't be used for passwords or digital signatures. It's still fine for non-security checksums, like verifying a file wasn't corrupted during a download.
Both are currently considered secure. SHA-512 produces a longer 512-bit digest and can be faster on 64-bit systems, while SHA-256 is more widely used and sufficient for the vast majority of use cases.
No. Hash functions are one-way — there's no mathematical way to recover the input from the output. Attackers instead try to guess the input and compare hashes, which is why long, unpredictable inputs are harder to crack.
No. This tool hashes everything directly in your browser — nothing you type or upload ever leaves your device.
