About Hash Functions
Supported Algorithms
- SHA-1: 160-bit hash (40 hex characters) - Legacy use only
- SHA-256: 256-bit hash (64 hex characters) - Most common
- SHA-384: 384-bit hash (96 hex characters) - High security
- SHA-512: 512-bit hash (128 hex characters) - Highest security
Common Use Cases
- Data Integrity: Verify files haven't been modified
- Password Storage: Store password hashes securely
- Digital Signatures: Sign documents and code
- Checksums: Validate downloaded files
What is a Hash Function?
A cryptographic hash function takes an input and produces a fixed-size output (the hash or digest). The same input always produces the same hash, but it's computationally infeasible to reverse the process or find two inputs with the same hash.
Security Note
SHA-1 is considered cryptographically weak and should only be used for non-security purposes. For security applications, use SHA-256 or higher. All hashing is performed locally in your browser using the Web Crypto API.
