About Hash Generator
A hash generator creates cryptographic hash values from text input. Hashes are one-way functions that convert data of any size into a fixed-size string of characters. They're commonly used for data integrity verification, password storage, and digital signatures.
Supported Hash Algorithms
- MD5: 128-bit hash (deprecated for security, but still used for checksums)
- SHA-1: 160-bit hash (deprecated for security-sensitive applications)
- SHA-256: 256-bit hash (part of SHA-2 family, widely used and secure)
- SHA-512: 512-bit hash (most secure in SHA-2 family)
Common Uses
- Verify file integrity and downloads
- Generate checksums for data validation
- Create unique identifiers for content
- Password hashing (with salt)
- Digital signature creation
- Blockchain and cryptocurrency operations
Security Notes
- MD5 and SHA-1 are considered cryptographically broken and should not be used for security purposes
- SHA-256 and SHA-512 are currently secure for most applications
- For password storage, use specialized algorithms like bcrypt, scrypt, or Argon2
- Always add a salt when hashing passwords
- Hashes are one-way - you cannot reverse them to get the original input
