In an authorization file on the host where the SSH server is must your public key be placed before you can connect.
Public and private keys are functional parts of public key cryptography. Together, they encrypt and decrypt data as it travels over or over networks. The public key is truly public and can be shared widely, while the private key should be known only to its owner.
A private key, like a password, is a very large number used in encryption. Private keys are used to create digital signatures that can be easily verified without exposing the private key.
A private key, also known as a private key, is a cryptographic variable used by algorithms to encrypt and decrypt data. Private keys should only be shared with key generators or parties authorized to decrypt data.
