RC4 Encryption Algorithm - GeeksforGeeks
WEBApr 24, 2023 · RC4 Encryption Algorithm. Last Updated : 24 Apr, 2023. RC4 is a stream cipher and variable-length key algorithm. This algorithm encrypts one byte at a time (or larger units at a time). A key input is a pseudorandom bit generator that produces a stream 8-bit number that is unpredictable without knowledge of input key, The output of the …
