County of Union, New Jersey. Although the issuance of passports is done by the federal passport agency, the County Clerkâs Passport Office, acting as an agent, is available to assist in the preparation of the application which, in turn, is forwarded to the State Department.
A problem with asymmetric encryption, however, is that it is slower than symmetric encryption. It requires far more processing power to both encrypt and decrypt the content of the message. To use asymmetric encryption, there must be a way for people to discover other public keys.
An example of a symmetric algorithm is DES. Asymmetric ciphers (also called public-key cryptography) make a public key universally available, while only one individual possesses the private key. When data is encrypted with the public key, it can only be decrypted with the private key, and vice versa.
