Specifications of CRYPTREC Ciphers List

“The list of ciphers that shoud be referred to in the procurement of the e-Government system(CRYPTREC Ciphers List)”(last revision: May 16,2024, CRYPTREC LS-0001-2022R1) consists of three lists: “e-Government Recommended Ciphers List”, “Candidate Recommended Ciphers List” and “Monitored Ciphers List”.
The specifications of the ciphers in these lists are shown in the following tables. Please note that the ciphers listed in the “CRYPTREC Ciphers List” are limited to those in the following tables. For the specifications of the ciphers in the previous “e-Government Recommended Ciphers List”, please refer to “Specifications of e-Government Recommended Ciphers”.
