How to use SHA Hash Generator
Enter text and compute digests with the Web Crypto API. Input never leaves your browser.
Understanding the results
Each algorithm returns a fixed-length digest for the exact input text you provide.
Limitations
- Hashing is not encryption and cannot be reversed to recover arbitrary input.
- SHA-1 is weaker for collision resistance than SHA-256 or SHA-512.
Privacy note
Hashing runs locally in your browser.
Frequently asked questions
What is a cryptographic hash?
A hash is a fixed-length digest derived from input. Small input changes produce very different digests.
Is hashing the same as encryption?
No. Hashing is one-way. Encryption is designed to be reversible with a key.
Is the input uploaded?
No. Digests are computed locally in your browser.
