Guide
How to use this tool
- 1
Enter text
Paste the value whose digest you want to calculate.
- 2
Choose an algorithm
Select SHA-256, SHA-384 or SHA-512.
- 3
Copy the hash
Use the digest for comparison or integrity checking.
Examples
Tips and best practices
- Use SHA-256 or a longer variant for modern integrity checks.
- A simple hash is not suitable for secure password storage.
- Always compare digests produced with the same algorithm and encoding.
Frequently asked questions
Can a hash be decrypted?
No. Hash functions are designed to be one-way, although weak inputs may be recovered through guessing or dictionaries.
Which algorithm should I choose?
SHA-256 fits most common integrity checks. SHA-384 and SHA-512 produce longer digests.
Can I hash a password with this tool?
You can for testing, but real password storage requires a dedicated salted, adaptive function such as Argon2, scrypt or bcrypt.
