RSA Key Pair Generator is an online tool that can help you create a pair of public and private keys for RSA encryption and decryption.

RSA is an asymmetric encryption algorithm that uses two different keys to encrypt and decrypt data. With RSA, you can securely share sensitive information with others by using their public key to encrypt the data and your private key to decrypt it.

To use this tool, you can follow these steps:

Select the RSA key size. The key size determines the strength of the encryption and the length of the keys. The larger the key size, the more secure the encryption, but also the longer it takes to generate and process the keys. The recommended key size is 2048 bits or higher.

Click on the Refresh Key-Pair button. The tool will generate a random pair of public and private keys based on your selected key size. The keys will be displayed in Base64 encoded format, which is a standard way of representing binary data as text.

Copy the public and private keys to your clipboard or save them to a file. You can also share your public key with others who want to communicate with you securely. You should never share your private key with anyone, as it is used to decrypt the data that is encrypted with your public key.
