/*

||
testSharpID に対応したフォーマットで ID の出力を行います。
|
||
|
||
*注意1* HSM の使える環境(Linux) で出力したファイルを Windows(Cygwin) で検証する場合、
|
||
文字コードを Shift-JIS の CR+LF として解釈するためうまくいきません(2つめのレコードでコケる)
|
||
Windows 側で検証する場合は LF として保存しなおす必要があります。
|
||
|
||
*注意2*
|
||
testSharpID で検証する場合は真の鍵で行う必要があります。
|
||
そのため Makefile.testSharpID において
|
||
|
||
(1) dummyKey フォルダの dev, prod それぞれに対して
|
||
eFuse_aesKey.bin, eFuse_privKey.der, eFuse_pubKey.der を差し替える (他はそのままで OK)
|
||
|
||
(2) realKey フォルダの dev, prod それぞれに対して
|
||
eFuse_aesKey.bin, eFuse_privKey.der, eFuse_pubKey.der を置く。
|
||
dummyKey フォルダの dev, prod の NCT2_priv.der, NCT2_priv.pem, NCT2_pub.pem を置く。
|
||
上記を行った上で Makefile.testSharpID の ifeq ($(USE_DUMMY_KEY),TRUE) endif の間にある
|
||
DEV_DER_KEY_DIR = ./dummyKey/dev -> ./realKey/dev
|
||
PROD_DER_KEY_DIR = ./dummyKey/prod -> ./realKey/prod
|
||
と変更する。
|
||
|
||
のいづれかの対応をします。
