In addition, authentication using publickey encryption limits message repudiation: if a message is confirmed as authentic, the sender cannot easily deny sending it.
A digital certificate associates a publickey with an entity's identity.
The additions include publickey encryption, composite keys, arbitrary regular guards and function symbols.
Sharable assemblies must have strong names, which include a publickey, file hashes, and a major.minor.build.revision version.
Typically, publickey techniques are much more computationally intensive than symmetric algorithms.
A number of ways have been devised including physically delivering the key, using a third trusted party or using a publickey cryptosystem.
The private key is kept secret, while the publickey may be widely distributed.
Publickey encryption can be used for authentication purposes.
Publickey cryptography is asymmetric: it involves the use of two separate keys which are related mathematically, designated as public and private keys.
Publickey cryptography works in the following way.
