WebThe RC4 Cipher Suites are considered insecure, therefore should be disabled. Note: RC4 cipher enabled by default on Server 2012 and 2012 R2 is RC4 128/128. The use of RC4 may increase an adversaries ability to read sensitive information sent over SSL/TLS. The RC4 Cipher Suites will not be available. WebRC4 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" [9] (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. [10] WebThe online RC6 encryption and decryption tool provides online RC6 encryption and decryption test. The encryption and decryption supports five encryption modes: CBC, CFB, OFB, CTR and ECB, and the input and output supports three formats: hex, string and base64. philipp ottenburg
