RC4 was designed by Ron Rivest of RSA Security in 1987. It stands for "Rivest Cipher 4", or alternatively for "Ron's Code".
RC4 was a widely-used cipher which has the following related algorithms, RC2, RC5, and RC6.
Important: Multiple vulnerabilities have been discovered in the RC4 cipher, rendering it insecure.
Micro Focus no longer uses this cipher in its products. Attempts to configure the RC4 algorithm will result in configuration errors.
