SHA Hash Result
Enter text or choose a file to generate SHA hash
Hash Validation
Verify SHA hash integrity by comparing it with the original text
About SHA
SHA (Secure Hash Algorithm) is a family of cryptographic hash functions designed by the NSA
SHA Algorithms
-
SHA-1: SHA-1 produces 160-bit hash but is deprecated due to security vulnerabilities
- SHA-256: SHA-256 produces 256-bit hash and is currently secure for use
- SHA-512: SHA-512 produces 512-bit hash and provides high security
- SHA-3: SHA-3 is the latest standard with completely different structure
Security Uses
Common Applications
- Digital signatures
- File integrity verification
- Password hashing
- Blockchain technology
- Digital certificates
- Digital forensics
Security Considerations
- Do not use SHA-1 for new security applications
- Always use unique, random salts with passwords
- Consider key stretching algorithms like bcrypt for passwords
- Use cryptographically secure random number generators
Warning: SHA-1 is deprecated and should not be used for security applications
