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
whats your OS? I assume you are trying commands from this page? https://code.google.com/p/chromium/issues/detail?id=58831 what was the exact command you entered?

what was your command exactly, and did you attempt to quote the argument containing the slash? – Frank Thomas – 2013-07-08T19:55:31.357
I'm playing around with Google Chrome and also with Chromium and have to double-check if they both use the same command-line args. – qbi – 2013-07-08T20:40:40.483
