Hash Generator
Generate SHA-1, SHA-256, SHA-384 or SHA-512 hashes from a text. Use it to check integrity, compare values and test applications.
How to use
- Type or paste the text.
- Choose the hash algorithm.
- Press Generate hash and copy the hexadecimal result.
SHA-1 is weak for security. For passwords, use dedicated derivation algorithms such as bcrypt or Argon2.
Frequently asked questions
Which algorithm should I use?
SHA-256 is a safe choice for most integrity checks.
Can I reverse a hash?
No. Hash functions are one-way and do not allow recovering the original text.
Does the same text produce the same hash?
Yes, as long as the algorithm is the same.
