The improvement of computer performance causes the decrease of the cipher strength, because the safety of the cipher is based on the difficulty of the decipherment calculation. According to the investigation report concerning the generation change of the cipher, the cipher with still low safety is used, and problems for solution by both the browser side and the server side. In this paper, we suggest the cipher confirmation service to confirm the cipher that the user is using ,and we suggest method to visualize the safety to lead the user to the cipher use with high safety.
