Frequently Asked Questions
What is SHA256?
SHA256 is a cryptographic hash function that converts any input into a fixed 64 character hexadecimal string. It is part of the SHA-2 family designed by the NSA.
What is SHA256 used for?
SHA256 is used for password hashing, digital signatures, blockchain transactions, file integrity verification and SSL certificate generation.
What is the difference between SHA256 and MD5?
SHA256 produces a 64 character hash and is cryptographically stronger than MD5 which produces 32 characters. MD5 has known vulnerabilities making SHA256 the preferred choice for security.
Can SHA256 be reversed?
No. SHA256 is a one-way function. It is computationally infeasible to reverse a SHA256 hash back to the original input.
Is my data sent to your servers?
Never. All hashing uses the browser's built-in Web Crypto API. Your input never leaves your device.
