SHA Signature Checker
Verify SHA checksums for files and text to ensure data integrity
How to Use
- Enter or paste the text you want to hash
- Select the SHA algorithm (SHA-256 recommended)
- View the computed hash result
- Optionally enter an expected hash to verify a match
Frequently Asked Questions
What is SHA?
SHA (Secure Hash Algorithm) generates a fixed-size hash value from input data. It's commonly used to verify file integrity and detect unauthorized modifications.
Which algorithm should I use?
SHA-256 is recommended for most uses. SHA-1 is legacy and no longer secure. SHA-384 and SHA-512 offer higher security but are slower.
Are hashes case-sensitive?
No, hashes are case-insensitive when comparing. 'ABC123' and 'abc123' are considered the same hash value.
