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.
The algorithm described by AES is a symmetric-key algorithm, meaning the same key is used for both encrypting and decrypting. In the United States, AES was announced by the NIST as U.S. FIPS PUB 197 (FIPS 197) on November 26, 2001.
