Hello,

I currently have the following directive in http-ssl.conf:

SSLCipherSuite ALL:!MD5:!RC4:!ADH:!EXPORT:!SSLv2:RC4+RSA:+HIGH:!MEDIUM:!LOW

How would I go about ensuring that all 64-bit ciphers are disabled?

The question arises due to the Sweet32 vulnerability.

Many thanks.

Checkout which of your ciphers have 64 bit.


Code:
openssl ciphers -v 'ALL:COMPLEMENTOFALL'
