Frequently Asked Questions
What is SHA-256?
SHA-256 (Secure Hash Algorithm 256-bit) is a cryptographic hash function that produces a 64-character hexadecimal digest. It is used for data integrity verification, digital signatures, and password hashing.
Is my text sent to a server when hashing?
No. All hashing is performed locally in your browser using the Web Crypto API (crypto.subtle.digest). Your data never leaves your device.
Can I reverse a SHA-256 hash back to text?
No. Cryptographic hashes are one-way functions. It is computationally infeasible to reverse a SHA-256 hash back to its original text - that is what makes hashing secure.
