- Hash is generated in real-time as you type
About This Tool
SHA-256 (Secure Hash Algorithm 256-bit) is a cryptographic hash function that produces a 256-bit (64-character hexadecimal) hash value. It's part of the SHA-2 family and is widely considered secure for cryptographic purposes. SHA256 is used extensively in blockchain technology, digital signatures, SSL/TLS certificates, and password hashing (with salt). It provides a good balance between security and performance.
Use Cases
- •Password hashing: Securely hash passwords with salt (use bcrypt for better security)
- •Blockchain and cryptocurrency: Generate transaction hashes and block hashes
- •Digital signatures: Create message digests for signing documents
- •SSL/TLS certificates: Verify certificate integrity and authenticity
- •Data integrity: Verify files and data haven't been tampered with
- •API authentication: Generate secure tokens and API keys
- •Git commit hashes: Version control systems use SHA256 for commit identification
