The RC2 key size can range from 8 to 256 bits. RC4 A proprietary algorithm developed by RSA Data Security, Inc., RC4 is a stream cipher. A stream cipher encrypts one byte at a time. The RC4 key size ...

RC4, being a stream-cipher mechanism, means that it generates a key stream that is the same length as the data stream. So 200 bytes of data would generate 200 bytes of a key stream, which is a ...

Microsoft released optional security updates Tuesday for various versions of the .NET Framework that prevent the RC4 encryption algorithm from being used in TLS (Transport Layer Security) connections.
