Hash Generator – Generate SHA Hashes Online
Enter any text and instantly generate its cryptographic hash using SHA-1, SHA-256, SHA-384, or SHA-512. All hashing happens in your browser — nothing is sent to a server.
How to Use
- 1
Type or paste the text you want to hash into the input field
- 2
Select the hash algorithm (SHA-1, SHA-256, SHA-384, or SHA-512)
- 3
Click 'Generate Hash' and copy the hex result
Frequently Asked Questions
What is a hash?
A cryptographic hash is a fixed-length string generated from input data. The same input always produces the same hash, but the hash cannot be reversed to recover the original text.
Which algorithm should I use?
SHA-256 is the most widely used for general purposes. SHA-512 provides extra security. SHA-1 is considered weak for security but still used for checksums.
Is my text sent to a server?
No. All hashing is performed entirely in your browser using the native Web Crypto API. No data leaves your device.
Can I hash a password with this tool?
For displaying a hash yes, but for storing passwords you should use dedicated password hashing algorithms like bcrypt or Argon2, not SHA.
Generate cryptographic hashes
A hash generator turns any text into a fixed-length fingerprint using algorithms like SHA-1, SHA-256, SHA-384 and SHA-512. The same input always produces the same hash, but the process cannot be reversed to recover the original text.
Hashes are used to verify that data has not changed and to store fingerprints rather than raw values.
What hashes get made for
- Verifying file integrity with a checksum.
- Generating fingerprints for data and caching.
- Learning how cryptographic hashing works.
- For reversible encoding use the Base64 encoder; to create strong secrets, the password generator.
