The following two 3DES cipher suites are reported as a equivalent to a 112-bit key.
TLS_RSA_WITH_3DES_EDE_CBC_SHA (0xa) 112
TLS_ECDHE_RSA_WITH_3DES_EDE_CBC_SHA (0xc012) ECDH 256 bits (eq. 3072 bits RSA) FS 112
What is 3DES?
3DES is a mode of DES encryption algorithm that encrypts data three times. This is completed by using three 56-bit keys, instead of one key, for an overall key length of 168-bits.
Why are 3DES cipher suites reported as a 112-bit key instead of 168-bit?
Triple DES has a key size of 168 bits but provides at most 112 bits of security.This property of Triple DES is not a weakness provided 112 bits of security is sufficient for an application.
You can chose to disable 3DES on the PCS device under Configuration > Security >SSL options > Allowed Encryption Strength > Custom SSL Cipher Selection.
