💡About RSA Key Generator

The RSA Key Generator helps you create secure RSA public and private key pairs for encryption, decryption, digital signatures, and other security applications.

Key Length Explanation

•
1024 bits: Lower security, not recommended for new systems
•
2048 bits: Currently recommended minimum secure length
•
3072 bits: Provides higher security
•
4096 bits: Maximum security, but slower to generate and use

Output Format Explanation

•
PEM: Standard PEM format with BEGIN/END markers, most commonly used format
•
Base64: Raw Base64 encoding without PEM markers
•
HEX: Hexadecimal format, useful for debugging and analysis

Usage Instructions

Private keys are used for decryption and digital signing, must be kept secret. Public keys are used for encryption and signature verification, can be shared publicly. Keep your private key safe and never share it with others.
