What is a Hash Generator?

A hash generator is a free online tool for generating cryptographic hashes from text input. It supports the SHA-1, SHA-256, SHA-384 and SHA-512 algorithms. All computations happen in the browser using the native Web Crypto API.

How to generate a hash

Type or paste text into the input field. Select the hash algorithm from the dropdown. The hash is generated and displayed in the output field immediately.

Understanding hash algorithms

SHA-256 and SHA-512 are the recommended cryptographically secure algorithms. SHA-256 produces a 256-bit (32-byte) hash, usually represented as 64 hexadecimal characters. SHA-512 produces a 512-bit (64-byte) hash.

Common uses of hashes

  • Verifying file integrity
  • Storing passwords securely (with salting)
  • Generating unique identifiers for data
  • Creating digital signatures
  • Indexing data in hash tables

Frequently Asked Questions

What is a hash generator?+
A hash generator is a tool that converts input text into a fixed-length string. Hashes are one-way — you cannot reverse a hash back into the original text. They are used for data integrity, password storage and digital signatures.
Which hash algorithms are supported?+
The tool supports SHA-1, SHA-256, SHA-384 and SHA-512. SHA-256 and SHA-512 are recommended for secure applications. SHA-1 is no longer recommended for security reasons but may be used for legacy systems.
How do I generate a hash?+
Type or paste text into the input field. Select the desired hash algorithm. The hash is generated and displayed immediately. Click copy to copy it to your clipboard.
Are the hashes secure?+
SHA-256 and SHA-512 are currently considered secure. SHA-1 has known collision vulnerabilities and should not be used for security purposes. For password hashing, use dedicated functions such as bcrypt or Argon2.
Can I hash files?+
The current version only supports text input. For file hashing, you need to read the file contents and pass them as text.
Is hashing safe in the browser?+
Yes. All hashing is done in the browser using the native Web Crypto API. No data is sent to any server.
