SHA-256 Hash Generator
Generate SHA-256 and other cryptographic hashes
SHA-256 Hash Generator creates secure cryptographic hashes from any text input. SHA-256 is part of the SHA-2 family and produces a 256-bit (32-byte) hash. It's widely used for data integrity verification, password storage, digital signatures, and blockchain technology.

About Cryptographic Hashing
What is SHA-256? SHA-256 (Secure Hash Algorithm 256-bit) is a cryptographic hash function that produces a fixed 256-bit output regardless of input size. It's part of the SHA-2 family designed by the NSA.
Properties: Cryptographic hashes are one-way functions (cannot be reversed), deterministic (same input = same output), and collision-resistant (extremely unlikely for two different inputs to produce the same hash).
Common Uses: Verifying file integrity, storing passwords securely, digital signatures, SSL/TLS certificates, Git commits, Bitcoin mining, and blockchain transactions.
Security Note: While SHA-256 is secure for most purposes, for password hashing consider using specialized algorithms like bcrypt, scrypt, or Argon2 that include salt and are designed to be slow.
