  3. Copy the hash you need
  4. Use for verification

About This Tool


Hash functions convert any input into a fixed-size string of characters. The same input always produces the same hash, but even tiny changes completely alter the output.

MD5 produces a 128-bit hash and is fast but no longer considered cryptographically secure. It is still useful for checksums and non-security purposes.

SHA-256 is part of the SHA-2 family and produces a 256-bit hash. It is currently considered secure and is used in Bitcoin and many security applications.

SHA-512 provides even more security with a 512-bit output. It is recommended for the highest security requirements.

Note: For password storage, use specialized password hashing algorithms like bcrypt or Argon2, not plain SHA hashes.

FAQ

What is a hash function?
A hash function converts input data into a fixed-size string. The same input always gives the same hash, but you cannot reverse it to get the original.
Is MD5 still safe to use?
MD5 is broken for security purposes but fine for checksums and non-security uses like cache keys.
Which hash should I use?
SHA-256 is recommended for most purposes. Use SHA-512 for highest security. Avoid MD5 and SHA-1 for security.
Can I unhash a value?
No, hash functions are one-way. You cannot reverse a hash to get the original input.
Should I hash passwords with SHA-256?
No, use specialized password hashing like bcrypt or Argon2 which include salting and are intentionally slow.
