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.
II. Symmetric algorithms: As the name suggests, symmetric key algorithms use the same key to encrypt as well as decrypt message. Some of the commonly used symmetric key algorithms are: DES (Data Encryption Standard): DES uses a 56-bit key on each 64-bit chunk of data. It is limited in used due to its short key length.
