🔐 RSA Key Pair Generator

Generate RSA public and private key pairs for cryptographic operations

RSA Key Pair Generator Tool

This tool generates RSA public and private key pairs for cryptographic operations. RSA is a widely used asymmetric encryption algorithm that uses a pair of mathematically related keys - a public key for encryption and a private key for decryption.

Bits:

Public Key

Private Key

Features:

Generate RSA key pairs with configurable bit lengths (256-16384 bits)
Standard PEM format output for both public and private keys
Secure key generation using node-forge library
Real-time validation of bit length requirements
Easy copy and clear functionality

Important Notes

RSA key pairs are used for asymmetric encryption, digital signatures, and secure communication. The public key can be shared freely, while the private key must be kept secure and confidential. Key strength increases with bit length, but generation time also increases. 2048 bits is currently recommended for most applications.
