I see 

crypto: assign driver 0, flags 2
crypto: driver 0 registers alg 1 flags 0 maxoplen 0
crypto: driver 0 registers alg 2 flags 0 maxoplen 0
crypto: driver 0 registers alg 3 flags 0 maxoplen 0
crypto: driver 0 registers alg 4 flags 0 maxoplen 0
crypto: driver 0 registers alg 5 flags 0 maxoplen 0
crypto: driver 0 registers alg 17 flags 0 maxoplen 0
crypto: driver 0 registers alg 6 flags 0 maxoplen 0
crypto: driver 0 registers alg 7 flags 0 maxoplen 0
crypto: driver 0 registers alg 15 flags 0 maxoplen 0
crypto: driver 0 registers alg 8 flags 0 maxoplen 0
crypto: driver 0 registers alg 16 flags 0 maxoplen 0
crypto: driver 0 registers alg 9 flags 0 maxoplen 0
crypto: driver 0 registers alg 10 flags 0 maxoplen 0
crypto: driver 0 registers alg 13 flags 0 maxoplen 0
crypto: driver 0 registers alg 14 flags 0 maxoplen 0
crypto: driver 0 registers alg 11 flags 0 maxoplen 0
crypto: driver 0 registers alg 18 flags 0 maxoplen 0
