DES-CBC3-SHA listed as 192 bits but SSL Labs reports as 112 bit
In the table here under the BIG-IP 11.5.0 - 11.5.2 section it lists the DES-CBC3-SHA ciphers as 192 bits.
However a SSL Labs scan will report the following:
TLS_RSA_WITH_3DES_EDE_CBC_SHA (0xa)112 [bits]
I'm not a crypto-nerd but if I read this explanation correctly that particular cipher has an effective security of 112 bits but if the encryption is achieved by using 3 56 bit keys (3 X 56 = 168) why is F5 reporting 192 bits?
