Hash Generator
Generate cryptographic hashes using various algorithms
Input Data
Enter text or hexadecimal data to generate hashes
Algorithm Info
MD5
128-bit (32 hex chars) - Fast but not secure
SHA-1
160-bit (40 hex chars) - Legacy, avoid for security
SHA-256
256-bit (64 hex chars) - Secure and widely used
SHA-512
512-bit (128 hex chars) - Very secure
SHA3-256
256-bit (64 hex chars) - Latest SHA-3 standard
SHA3-512
512-bit (128 hex chars) - Latest SHA-3 standard
About Hash Functions
Hash functions are one-way mathematical functions that convert input data of any size into a fixed-size string of characters, typically a hexadecimal number.
- Deterministic: The same input always produces the same hash
- Fixed Output: Hash length is constant regardless of input size
- Avalanche Effect: Small input changes cause large hash changes
- One-way: Computationally infeasible to reverse
- Collision Resistant: Hard to find two inputs with the same hash
Security Note: MD5 and SHA-1 are cryptographically broken and should not be used for security purposes. Use SHA-256, SHA-512, or SHA-3 for secure applications.
