Question 1

Which hash algorithms are supported?

Accepted Answer

MD5, SHA-1, SHA-256, SHA-384, and SHA-512. SHA-256 is a good default for most integrity and checksum needs.

Question 2

Is hashing reversible?

Accepted Answer

No. Cryptographic hashes are one-way functions — you cannot recover the original input from the hash. This tool only computes, it does not decrypt.

Question 3

Should I use MD5 or SHA-1 for security?

Accepted Answer

No. MD5 and SHA-1 are broken for security purposes and should only be used for non-security checksums. Use SHA-256 or higher for security.

Question 4

Is my input sent to a server?

Accepted Answer

No. All hashing happens in your browser; your text is never uploaded.

Question 5

Can I verify a file checksum?

Accepted Answer

Yes. Paste the text or value and compare the generated digest against the expected checksum.
