Is MD5 safe to use for passwords?

No — MD5 is fast and has known collision weaknesses, which makes it unsuitable for password storage. Use it for checksums or non-security identifiers, not for hashing secrets.

Which hash should I use for security purposes?

SHA-256 or SHA-512 are the current standards for integrity checks and cryptographic use. For password storage specifically, a dedicated slow hash like bcrypt or Argon2 is the right tool — not a general-purpose hash function.

Is my text sent to a server to compute the hash?

No. SHA hashes are computed with your browser's native Web Crypto API and MD5 with an in-browser JavaScript library — your input never leaves your device.

Common use cases

Verifying a downloaded file's integrity

Compare the SHA-256 of a downloaded installer or archive against the checksum published by its source.

Generating a cache-busting key

Hash a file's contents to produce a short, stable identifier that changes only when the file actually changes.

Creating a deterministic ID from a string

Turn an email address or URL into a consistent short identifier without needing a database lookup.

How to use the Hash Generator

Type or paste any text into the input box.

MD5, SHA-1, SHA-256 and SHA-512 hashes are computed instantly and shown below, side by side.

SHA-family hashes use your browser's built-in Web Crypto API; MD5 uses a small, well-tested JavaScript implementation since browsers don't expose MD5 natively.
