Frequently Asked Questions
What is SHA-256 Hashing?
SHA-256 is a cryptographic hash function that generates a fixed 64-character hexadecimal string representing any data. It is considered highly secure and is widely used in SSL certificates, blockchain (like Bitcoin), and password storage.
Is SHA-256 reversible?
No, SHA-256 is a one-way hashing function. Once a string is hashed, it cannot be reversed to its original form. This is why it is perfect for storing sensitive data.
Is my text sent to a server?
No. Your text is hashed locally inside your browser using the native Web Crypto API. It never leaves your device.
