* The Keys used for encryption and decryption in RSA algorithm, are generated using random data ( 300-400 digit). The key used for encryption is a public key and the key used for decryption is a private key. Public keys are stored anywhere publicly accessible. The sender of message encrypt the data using the receiver's public key, and the receiver decrypt it using its own private key. That's. The RSA cryptosystem is one of the first public-key cryptosystems, based on the math of the modular exponentiations and the computational difficulty of the RSA problem and the closely related integer factorization problem (IFP).The RSA algorithm is named after the initial letters of its authors (R ivest- S hamir- A dleman) and is widely used in the early ages of computer cryptography

Type ssh-keygen and hit the Enter key. The app will ask for the save location, offering C:\users\your user name\.ssh\id_rsa by default. Next, you will be prompted to enter a passphrase. You can just hit the Enter key to skip it. Finally, you will see the fingerprint for your key and SHA256. The default algorithm is RSA 2048. You. SSH keys grant access, and fall under this requirement. This, organizations under compliance mandates are required to implement proper management processes for the keys. NIST IR 7966 is a good starting point. Conclusion. You should now be able to generate ssh keys, add them to an authorized server and using the generate private key
