Hashing
SHA-256 Generator
Generate SHA-256 hex digests locally with browser crypto. Hashing is one-way and is not encryption.

How this tool works
SHA-256 produces a fixed-length digest from input text.
It is useful for checksums and integrity comparisons, but password storage requires dedicated password hashing algorithms and salts.
Examples
- Hash a sample payload for a test assertion.
- Compare two pieces of text by checking their SHA-256 digests.
Common use cases
Integrity checks
Test fixtures
Digest comparisons
FAQ
Is SHA-256 encryption?
No. SHA-256 is a one-way hash function, not reversible encryption.
Is the input uploaded?
No. crypto.subtle.digest runs in the browser.
