I want to remove RC4 from Google Chrome and found the commandline option
--cipher-suite-blacklist. However I wasn't able to figure out what the correct notation for RC4 is. Whatever I tried so far only brought the message:
ERROR:ssl_config_service_manager_pref.cc(55)] Ignoring unrecognized or \ unparsable cipher suite:
Even the names listed in
ssl_cipher_suite_names.cc don't work. What should I enter to remove RC4 as a cipher for SSL/TLS?
I'm working with some different versions of GNU/Linux and sometimes also with Windows. So it would be nice if the command-line argument would work under all OSes. I used the following command:
chrome --cipher-suite-blacklist=TLS_RSA_WITH_RC4_128_MD5 --ssl-version-min=tls1.1 chrome --cipher-suite-blacklist=RC4 --ssl-version-min=tls1.1 chrome --cipher-suite-blacklist=0xXYZ,0xUVW --ssl-version-min=tls1.1 # XYZ and UVW are some hexadecimal numbers
