🔐 About RSA Encryption

Public Key: Used to encrypt messages or verify signatures. Safe to share publicly.
Private Key: Used to decrypt messages or create signatures. Must be kept secret.
2048-bit: Standard security level, suitable for most purposes
4096-bit: Higher security, slower performance but more future-proof

💡 Common Uses

Email Encryption: PGP/GPG email encryption
Digital Signatures: Prove message authenticity and integrity
SSH Authentication: Secure shell access to servers
Code Signing: Sign software packages and updates
SSL/TLS Certificates: Secure website connections (HTTPS)

⚠️ Important Notes

All key generation happens locally in your browser using Web Crypto API
Your keys never leave your device or get sent to any server
Make sure to backup your private key securely
Consider encrypting your private key with a strong password before storage
If you lose your private key, any encrypted data becomes unrecoverable
