About SHA-256
SHA-256 is part of the SHA-2 family and produces a 256-bit hash. It's widely used for security applications.
Security:
Strong - resistant to collision attacks
Use Case: Digital signatures, blockchain, password hashing

Frequently Asked Questions
Which hash algorithm should I use?
For security, use SHA-256 or higher. MD5 and SHA-1 are cryptographically weak and should only be used for non-security purposes like file integrity checks.
Are these hashes reversible?
No, hash functions are one-way. You cannot recover the original text from a hash. They're designed for integrity verification and password storage.
What's the difference between hashing and encryption?
Hashing is one-way and produces fixed-length output. Encryption is two-way and can be decrypted to recover the original data.
