About SHA Hashes
SHA-256 (Recommended)
Most widely used hash function. 256-bit output provides excellent security for most applications.
SHA-512
Stronger variant with 512-bit output. Better for high-security applications requiring maximum protection.
Frequently Asked Questions
Which hash algorithm should I use?
SHA-256 is the recommended choice for most use cases - it's secure and widely supported. Use SHA-512 for extra security. SHA-1 is deprecated, but still useful for legacy systems.
Can I verify file integrity with this?
Yes! Generate a hash of your file, share it with recipients. They can hash their copy and compare - matching hashes prove the file is identical and uncorrupted.
Is hashing the same as encryption?
No! Hashing is one-way - you can't reverse it to get the original. Encryption is two-way. Use hashing for verification (passwords, checksums), not for hiding secret data.
How are my hashes generated?
We use the Web Crypto API in your browser - the same secure technology used by banks and governments. Your data never leaves your device.
About the Hash Generator
A hash function turns any input into a fixed-length fingerprint. The same input always gives the same hash, and even a one-letter change gives a completely different one.
How to use it
- 1 Type text or choose a file.
- 2 Pick the hash algorithms you need.
- 3 Copy the hash or compare it with a published checksum.
Frequently asked questions
Can a hash be reversed?
No. Hashes are one-way. Short or common inputs can be guessed with lookup tables, which is why passwords need slow, salted hashes like bcrypt.
Which hash should I use?
SHA-256 is the standard choice for integrity checks. MD5 and SHA-1 are broken for security and should only be used for non-security checksums.
How do I verify a downloaded file?
Hash the file with the same algorithm the publisher used, then compare it with their checksum. If every character matches, the file is intact.
