Frequently Asked Questions
What is SHA-256?
SHA-256 (Secure Hash Algorithm 256-bit) is a cryptographic hash function that produces a 256-bit (32-byte) hash value. It is part of the SHA-2 family and is widely used for data integrity, digital signatures, and blockchain technology.
Is this SHA-256 generator secure?
Yes, all processing happens entirely in your browser using the Web Crypto API. No text or files are sent to any server. Your data never leaves your device.
Can I hash files with this tool?
Yes! Click "Upload File" and select any file. The SHA-256 hash will be generated instantly. This is useful for verifying file integrity and checksums.
How do I verify a hash?
After generating a hash, paste the expected hash into the "Verify Hash" field. The tool will instantly compare and tell you if they match, confirming data integrity.
What is the SHA-256 hash length?
A SHA-256 hash is always 64 hexadecimal characters (256 bits) long, regardless of the input size. It is displayed in hexadecimal format (0-9, a-f).
Is SHA-256 the same as SHA-2?
SHA-256 is one of several hash functions in the SHA-2 family. Other variants include SHA-224, SHA-384, and SHA-512. SHA-256 is the most commonly used variant.
