What is DLf3072s256mRijndael cipher suite?
Guessing: 


DL -> Discrete Logarithm
f -> finite field (of prime order)
3072 -> size of finite field in bits
s -> (not sure) SHA?
256 -> size of hash digest or subgroup size (used in DSA the old Digital Signature Algorithm?)
m -> don't know honestly. 
Rijndael -> AES.
