About SHA256 Hashing
SHA256 is a cryptographic hash function that produces a 256-bit (32-byte) hash value, typically rendered as a 64-digit hexadecimal number. It's part of the SHA-2 family and is widely used for its strong security properties.
Key features of SHA256:
- Fixed output length (64 hexadecimal characters)
- Deterministic (same input always yields same output)
- Avalanche effect (small input changes cause large output changes)
- One-way function (computationally infeasible to reverse)
- Collision resistant
Example SHA256 hashes:
- "hello" → "2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824"
- "test" → "9f86d081884c7d659a2feaa0c55ad015a3bf4f1b2b0b822cd15d6c15b0f00a08"
Security Notice:
SHA256 is currently considered cryptographically secure and is widely used in modern security applications. However, for password hashing, you should use specialized algorithms like bcrypt or Argon2.
Common Applications
SHA256 is commonly used in:
- Digital signatures and certificates
- Blockchain and cryptocurrency systems
- File integrity verification
- SSL/TLS security protocols
- Software distribution verification
Implementation Details:
This tool uses the Web Crypto API, providing a secure, browser-native implementation of SHA256. All hashing is performed locally in your browser, ensuring your data never leaves your device.
Verifying SHA256 Hashes:
- Generate a hash of your original content
- Save or share both the content and its hash
- Later, generate a new hash of the content
- Compare the new hash with the original hash
- If they match, the content is unchanged
