ℹ️ About Hash Algorithms

Understanding cryptographic hash functions and their security properties

🔒

SHA-256

Secure

Industry standard hash function used in Bitcoin, SSL certificates, and most modern applications. Provides 256-bit output with excellent security.

🛡️

SHA-512

Very Secure

Highest security level with 512-bit output. Used in high-security applications and when maximum security is required.

⚠️

SHA-1

Legacy

160-bit hash function. While still fast, it's considered cryptographically broken and should not be used for security purposes.

⚡

MD5

Broken

128-bit hash function. Very fast but cryptographically broken. Only suitable for non-security applications like checksums.

🔒

Security Note

Hash functions are one-way cryptographic functions. They cannot be reversed to recover the original input. This makes them perfect for password storage, digital signatures, and data integrity verification.

💡 Common Use Cases

🔐 Password hashing and verification
📄 File integrity checks (checksums)
🔒 Digital signatures and certificates
📊 Data deduplication and fingerprinting
⚡ Fast data comparison and lookup

⚙️ Technical Details

🔬
Collision Resistance: SHA-256 provides 128-bit collision resistance, making it virtually impossible to find two inputs that produce the same hash.
🔄
Avalanche Effect: A small change in input produces a completely different hash output, ensuring data integrity.
⚡
Performance: Modern hash functions are optimized for speed while maintaining security, making them suitable for real-time applications.
