WebApr 1, 2015 · A stream cipher encrypts plaintext messages by applying an encryption algorithm with a pseudorandom cipher digit stream (keystream). Each bit of the message is encrypted one by one with the corresponding keystream digit. Stream ciphers are typically used in cases where speed and simplicity are both requirements. WebFeb 14, 2024 · It encrypts messages one byte at a time via an algorithm. Plenty of stream ciphers exist, but RC4 is among the most popular. It's simple to apply, and it works quickly, even on very large pieces of data. If you've ever used an application like TSL (transport layer security) or SSL (secure socket layer), you've probably encountered RC4 encryption. WebJun 3, 2024 · A stream cipher works by generating a series of pseudorandom bytes which depend on the key (for any given key, the series of bytes is the same for encryption and decryption). Different keys will produce different strings of bytes. In order to encrypt data the plaintext bytes are XORed with the string of pseudorandom bytes. regal initials
