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.
A symmetric key is used during both the encryption and decryption processes. To decrypt a particular piece of ciphertext, the key that was used to encrypt the data must be used. The goal of every encryption algorithm is to make it as difficult as possible to decrypt the generated ciphertext without using the key.
