WebDec 15, 2011 · RC4 was invented in 1987 by Ron Rivest. It spent its first seven years as an RSA trade secret before it was eventually leaked to a public mailing list in 1994. The rest, as they say, is history. You could argue that RC4’s rise was inevitable. By the time of its leak, it was already in widespread commercial use.

WebHistory. RC4 was designed by Ron Rivest of RSA Security in 1987. While it is officially termed "Rivest Cipher 4", the RC acronym is alternatively understood to stand for "Ron's Code" (see also RC2, RC5 and RC6). RC4 was initially a trade secret, but in September 1994, a description of it was anonymously posted to the Cypherpunks mailing list. It was soon … WebApr 15, 2024 · RC4 is a broken algorithm and recommendation is to not use the same anymore if the data is to be kept highly secure. If you still need a working implementation, you don't need to recreate the algorithm in your code. Java API javax.crypto can do it for you. Just generate a key and call the init method with mode set to encryption/decryption.
