Frequently Asked Questions
Is my text sent to a server?
No. The hash is computed entirely in your browser using the Web Crypto API — nothing you type is ever transmitted anywhere.
What is SHA-256 used for?
SHA-256 is a cryptographic hash function used for verifying file integrity, generating checksums, storing password hashes (with proper salting), and in blockchain/Git internals.
Can I reverse a SHA-256 hash back to the original text?
No — SHA-256 is a one-way function by design. There is no way to recover the original input from the hash alone.
