There are symmetric and asymmetric crypto algorithms. Symmetric crypto algorithms use the same cryptographic key to encrypt and decrypt the data. Asymmetric crypto algorithms use a pair of keys - a public key and a private key. A public key can encrypt the data but cannot decrypt it. The private key can decrypt the data but cannot encrypt it.
The advantage of asymmetric encryption algorithms is that the keys can be safely exchanged between two parties. The problem is how to exchange the keys. That problem is solved in the form of a public key infrastructure (PKI). A PKI is a mechanism by which a client can obtain the public key of a server from a trusted third party - usually the certification authority. The certificate of the server is signed by the certification authority. For example, in a web of trust, the client can go to a certification authority and obtain the public key of the server from the certification authority. The certification authority can authenticate the public key of the server and can verify the authenticity and integrity of the public key of the server. The client can verify the validity of the public key of the server from the certification authority. If the client finds the public key of the server valid, then it can establish an encrypted communication channel using the public key of the server. If the client finds that the public key of the server is invalid or compromised, then it can establish the communication channel using the public key of a different server. Thus, the client can establish a communication channel with a server even if it cannot establish a communication channel with a third party. It can establish a communication channel with a server if the server does not publish the public key. 827ec27edc
