What is Hash Generator?

A hash generator creates fixed-size cryptographic hash values from input text using algorithms like SHA-256. Hash functions are one-way functions - you can generate a hash from data, but you cannot reverse it to get the original data. Hashes are used for data integrity verification, password storage, digital signatures, and more.

How to Use This Tool

  1. Enter or paste your text in the input field
  2. Click 'Generate Hashes' to compute all hash values
  3. View SHA-1, SHA-256, SHA-384, and SHA-512 results
  4. Copy any hash value using the copy button

Common Use Cases

  • Verifying file integrity after downloads
  • Creating unique identifiers from content
  • Password hashing for secure storage
  • Generating checksums for data comparison

Frequently Asked Questions

What is the difference between SHA-1, SHA-256, and SHA-512?

These are different SHA algorithms with increasing security levels. SHA-1 produces a 160-bit hash, SHA-256 produces 256 bits, and SHA-512 produces 512 bits. SHA-256 and SHA-512 are recommended for security-critical applications.

Is hashing the same as encryption?

No. Hashing is a one-way function - you cannot recover the original data from a hash. Encryption is two-way - encrypted data can be decrypted with the right key. Hashes are used for verification, encryption for confidentiality.

Why no MD5 option?

MD5 is considered cryptographically broken and unsuitable for security purposes due to collision vulnerabilities. For any security-related use, SHA-256 or SHA-512 should be used instead.
