What is SHA-512 hash?

SHA-512 (Secure Hash Algorithm 512-bit) is a cryptographic hash function that produces a 512-bit (64-byte) hash value, displayed as a 128-character hexadecimal number.

Key characteristics:
- Always produces 128 hexadecimal characters
- Most secure in SHA-2 family
- One-way function (cannot reverse)
- Slower but more secure than SHA-256

Example:
Input: "Hello" → SHA-512: 3615f80c9d293ed7402687f94b22d58e529b8cc7916f8fac7fddf7fbd5af4cf777d3d795a7a00a16bf7e7f3fb9561ee9baae480da9fe7a18769e71886b03f315

Used for: High-security applications, digital signatures, enterprise security.

Is SHA-512 more secure than SHA-256?

YES! SHA-512 provides higher security than SHA-256.

SHA-512 advantages:
✓ Longer hash (512 bits vs 256 bits)
✓ Larger security margin
✓ More collision-resistant
✓ Better for future-proofing

SHA-256 advantages:
✓ Faster on 32-bit systems
✓ Shorter hash output
✓ More widely supported
✓ Sufficient for most needs

When to use SHA-512:
✓ Maximum security required
✓ Long-term data integrity
✓ High-value transactions
✓ Enterprise applications

When SHA-256 is enough:
✓ General security needs
✓ Bitcoin/blockchain (uses SHA-256)
✓ SSL certificates
✓ Most applications

Both are secure; SHA-512 offers extra security margin.

What is SHA-512 used for?

SHA-512 is used in high-security applications:

✓ Enterprise Security:
- High-value data integrity
- Secure digital signatures
- Certificate authorities
- Government applications

✓ Cryptographic Systems:
- Key derivation (PBKDF2-SHA512)
- HMAC-SHA512
- Secure random number generation
- TLS 1.3 cipher suites

✓ Data Protection:
- Critical file verification
- Secure checksums
- Long-term archival
- Sensitive document hashing

SHA-512 provides maximum security for critical applications.

How do I generate a SHA-512 hash?

Enter your text and click 'Generate Hash':

1. Type or paste text
2. Choose format (lowercase or uppercase)
3. Click 'Generate Hash'
4. Copy the 128-character hash

Example:
Input: "password123"
SHA-512: (128 hex chars...)

Generated instantly using Web Crypto API.

Should I use SHA-512 instead of SHA-256?

It depends on your security requirements:

Use SHA-512 when:
✓ Maximum security needed
✓ Long-term data (10+ years)
✓ High-value applications
✓ Regulatory requirements
✓ Future-proofing

Use SHA-256 when:
✓ Standard security sufficient
✓ Blockchain compatibility
✓ Shorter hashes preferred
✓ 32-bit systems

Both are secure:
- SHA-256: 2^128 security
- SHA-512: 2^256 security

For most applications, SHA-256 is sufficient. Use SHA-512 for critical security needs.
