Frequently Asked Questions
What is SHA-256?
SHA-256 is a cryptographic hash function that produces a 256-bit (32-byte) hash value, typically rendered as a 64-character hexadecimal string.
Is SHA-256 secure?
Yes. SHA-256 is part of the SHA-2 family, designed by the NSA. It is computationally infeasible to reverse or find two inputs producing the same hash.
Is my data sent to a server?
No. All hashing is performed client-side in your browser using the Web Crypto API. Your data never leaves your device.
What can I use SHA-256 for?
File integrity verification, password hashing, digital signatures, blockchain, and any scenario requiring data integrity or uniqueness verification.
What is the output length?
SHA-256 always produces exactly 64 hexadecimal characters (256 bits / 4 bits per hex character).
