Private Key Generator
EDUCATIONAL USE ONLY - Generate cryptographic private keys for learning and testing purposes.
Security Warning
NEVER use generated keys for real Bitcoin storage!
- This tool is for educational/testing purposes only
- Keys generated in browsers are not secure
- Use hardware wallets or proper offline key generation for real funds

🔐 About Private Keys
A private key is a 256-bit number that controls access to Bitcoin addresses. This generator is for educational purposes only!
- Hex: 64 hexadecimal characters (most common)
- Base64: 44 characters using Base64 encoding
- WIF: Wallet Import Format (Bitcoin-specific)
Critical Security Warning
NEVER USE FOR REAL CRYPTOCURRENCY
Browser Generation: Not secure for real funds
No Hardware Security: Lacks proper entropy sources
Memory Exposure: Keys may remain in browser memory
Network Risk: Potential exposure through browser vulnerabilities
For Real Bitcoin Storage
Hardware Wallets: Ledger, Trezor, ColdCard
Offline Generation: Air-gapped computers
Proper Entropy: Hardware random number generators
Secure Storage: Paper wallets, steel backups
Understanding Private Keys
What is a Private Key?
A private key is a 256-bit number that controls access to Bitcoin addresses. Anyone with the private key can spend the associated Bitcoin.
Private Key → Public Key → Bitcoin Address

Production Security Checklist
When implementing real private key generation:
Recommended: Use hardware random number generators
Recommended: Generate keys offline (air-gapped)
Recommended: Implement proper entropy sources
Recommended: Use established cryptographic libraries
Recommended: Follow industry security standards
Recommended: Test with small amounts first
Recommended: Create secure backups
Avoid: Never generate keys in browsers
Avoid: Don't rely on Math.random()
Avoid: Avoid online key generators
Avoid: Don't store keys in plain text
Avoid: Never share private keys
Remember: This tool is for education only. Real cryptocurrency requires proper security measures!
