Hash Generator
Generate secure cryptographic hash values with MD5, SHA-1, SHA-256, and SHA-512 algorithms for data integrity and security verification
Input Data
Enter text or upload a file to generate cryptographic hashes
MD5
Message Digest 5 (128-bit) - Fast but not cryptographically secure
SHA-1
Secure Hash Algorithm 1 (160-bit) - Legacy, not recommended for security
SHA-256
Secure Hash Algorithm 256 (256-bit) - Recommended for security applications
SHA-512
Secure Hash Algorithm 512 (512-bit) - Highest security, larger output
Cryptographic Hash Applications
