About Hash Generator
Generate cryptographic hashes for any text using MD5, SHA-1, SHA-256, or SHA-512 algorithms. Useful for verifying file integrity, storing passwords (with proper salting), or generating checksums. All hashing happens locally in your browser.
Frequently Asked Questions
Which hash algorithm should I use?
For security purposes, use SHA-256 or SHA-512. MD5 and SHA-1 are considered weak for security but fine for checksums.
Can I reverse a hash to get the original text?
No, cryptographic hashes are one-way functions. You cannot reverse them to get the original input.
Why do different texts sometimes produce the same hash?
This is called a collision and is theoretically possible but extremely rare with strong algorithms like SHA-256. MD5 has known collision vulnerabilities.
Is this suitable for hashing passwords?
For password storage, you should use specialized algorithms like bcrypt or Argon2 with salting. Simple hashing is not secure enough for passwords.
