How to Use Hash Generator

  1. Type or paste text into the input field.
  2. All hash values (MD5, SHA-1, SHA-256, SHA-512) are computed in real-time.
  3. Click Copy next to any hash to copy it to your clipboard.
  4. Use the comparison field to verify a hash against the computed values.
  5. All hashing happens in your browser using the Web Crypto API.

Frequently Asked Questions

What is a hash?

A hash is a fixed-size string computed from input data. The same input always produces the same hash, but you cannot reverse a hash to get the original data.

Which hash algorithm should I use?

SHA-256 is recommended for most purposes. MD5 and SHA-1 are considered weak for security but still useful for checksums and non-security purposes.

Is this secure for password hashing?

These are general-purpose hash functions. For password hashing, use dedicated algorithms like bcrypt or Argon2 which include salting and key stretching.
