SHA256 Hash Generator

SHA256 (Secure Hash Algorithm 256-bit) is a cryptographic hash function that produces a 256-bit (32-byte) hash value, typically expressed as a 64-character hexadecimal number.

• Produces a 64-character hexadecimal hash
• One-way function (cannot be reversed)
• More secure than MD5 and SHA1
• Commonly used for digital signatures and blockchain

• Enter text or upload a file to generate its SHA256 hash
• Click "Generate Hash" to create the SHA256 hash
• Use the copy button to copy the hash to clipboard
• Click "Clear" to reset the form
