v. t. e. The Secure Shell Protocol ( SSH) is a cryptographic network protocol for operating network services securely over an unsecured network. [1] Its most notable applications are remote login and command-line execution. SSH was designed on Unix-like operating systems, as a replacement for Telnet and for unsecured remote Unix shell protocols ...
Keystream. In cryptography, a keystream is a stream of random or pseudorandom characters that are combined with a plaintext message to produce an encrypted message (the ciphertext). The "characters" in the keystream can be bits, bytes, numbers or actual characters like A-Z depending on the usage case. Usually each character in the keystream is ...
Listen with Friends. Listen with Friends allows Facebook users to listen to music and discuss the tunes using Facebook Chat with friends at the same time. Users can also listen in as a group while one friend acts as a DJ. Up to 50 friends can listen to the same song at the same time, and chat about it.
data encryption key (DEK) used to encrypt the underlying data. derived key - keys computed by applying a predetermined hash algorithm or key derivation function to a password or, better, a passphrase. electronic key - (NSA) key that is distributed in electronic (as opposed to paper) form. See EKMS.
2. When you get the pop-up notification asking would you be willing to accept all Facebook notifications, click "No." That should do the trick. Close the browser and re-launch AOL Shield Pro. Now you should be able to sign in to Facebook.
WEP used the RC4 algorithm for encrypting data, creating a unique key for each packet by combining a new Initialization Vector (IV) with a shared key (it has 40 bits of vectored key and 24 bits of random numbers). Decryption involved reversing this process, using the IV and the shared key to generate a key stream and decrypt the payload.
A stream cipher is a symmetric key cipher where plaintext digits are combined with a pseudorandom cipher digit stream ( keystream ). In a stream cipher, each plaintext digit is encrypted one at a time with the corresponding digit of the keystream, to give a digit of the ciphertext stream. Since encryption of each digit is dependent on the ...
Facebook Watch (currently rebranding to Facebook Video) is a video on demand service operated by American company Meta Platforms (previously named Facebook, Inc.). The company announced the service in August 2017 and it was available to all U.S. users that month. Facebook Watch's original video content is produced for the company by others, who ...
