Frequently asked questions

What hash algorithms are available?

MD5, SHA-1, SHA-256, and SHA-512 are all available.

What is hashing used for?

Verifying file integrity, storing passwords securely, generating checksums, and creating unique identifiers. Hashing is one-way: you cannot recover the original text from the hash.

Is MD5 secure for passwords?

No. MD5 and SHA-1 are considered cryptographically broken for security purposes. Use SHA-256 or SHA-512 for security-sensitive applications. MD5 is still useful for non-security checksums like verifying file downloads.

Why does the same text always produce the same hash?

Hashing is deterministic. The same input always produces the same output. This property is what makes hashes useful for verification.

Can two different inputs produce the same hash?

Theoretically yes, this is called a collision. For SHA-256 and SHA-512, collisions are computationally infeasible to find in practice.

Does it work offline?

Yes.
