🔐 Cryptographic Hash Generator
Generate SHA-256 and SHA-512 cryptographic hashes from text, hex, or binary strings
💡 About Cryptographic Hashing
SHA-256:
• 256-bit (32-byte) hash output
• 64 hexadecimal characters
• Used in Bitcoin & blockchain
• NIST standard algorithm
• 256-bit (32-byte) hash output
• 64 hexadecimal characters
• Used in Bitcoin & blockchain
