java card 更新密钥（put key command）java 卡密钥更新，通过获取随机数计算 check

第一步准备数据

Initial Key: 404142434445464748494A4B4C4D4E4F
New Key: 101112131415161718191A1B1C1D1E1F

第二步计算过程

1.发送apdu 指令 8050000008 86866C36D5B7C3B8
result = 0000EB5A87688768EB5A01020004D9D83827232277B1DB6B68A45837
VSeqCounter = 0004
IV: 0000000000000000
ENCSessionKey = 3DES_CBC("0181" + VSeqCounter + "000000000000000000000000") with inital Key
ENCSessionKey = 662D9905E05BC32564438EB82E28EE52

encrypted Key  = 3DES_ECB(new key) with ENCSessionKey
encrypted Key =C7E9B29D8F122420939C66FD24CFF343

KeyCheckValue - 3DES_CBC("0000000000000000") with new key =8BAF47
 
PutKey APDU = "80D8008143 + 01 + 8010 + C7E9B29D8F122420939C66FD24CFF343 + 03 + 8BAF47 + 8010 + C7E9B29D8F122420939C66FD24CFF343 + 03 + 8BAF47 + 8010 + C7E9B29D8F122420939C66FD24CFF343 + 03 + 8BAF47"
 
 注意 如果 enc ,mac ,dek 三个可以不同，重新 每个新key 重复上面的过程
 old_keyenc = 404142434445464748494A4B4C4D4E4F
//old_keymac = 404142434445464748494A4B4C4D4E4F
//old_keydek = 404142434445464748494A4B4C4D4E4F
