Hash Generator
Generate Hashes
How to Use
Input Methods
- Text Input: Type or paste text directly
- File Upload: Upload text files to hash their contents
Hash Algorithms
- MD5: 128-bit hash, fast but not secure
- SHA1: 160-bit hash, deprecated for security
- SHA256: 256-bit hash, secure and recommended
- CRC32: 32-bit checksum, for error detection only
Security Levels
- Strong: SHA256 - Use for passwords, certificates
- Weak: MD5, SHA1 - Avoid for security purposes
- Checksums: CRC32 - File integrity verification only
Use Cases
- File Integrity: Verify file hasn't been modified
- Password Storage: Store hashed passwords (use SHA256+)
- Digital Signatures: Verify data authenticity
- Data Deduplication: Identify identical files
Important Notes
- One-way: Hash functions cannot be reversed
- Deterministic: Same input always produces same hash
- Avalanche Effect: Small input changes create large hash changes
- Salt Passwords: Add random data before hashing passwords
