rk3568 android 11 更换系统签名

1.系统签名存放位置

build/make/target/product/security/ 主要有以下几个

media.pk8 networkstack.x509.pem shared.pk8 testkey.x509.pem
media.x509.pem platform.pk8 releasekey.pk8 shared.x509.pem verity.pk8
networkstack.pk8 platform.x509.pem releasekey.x509.pem testkey.pk8 verity.x509.pem

2.生成新的系统签名，使用development/tools/make_key 工具生成新的签名文件，不能输入密码。

./development/tools/make_key testkey ‘/C=US/ST=Michigan/L=Michigan/O=MicroTouch/OU=MicroTouch/CN=Mircotouch/emailAddress=max.chen@microtouch.com’
./development/tools/make_key releasekey ‘/C=US/ST=Michigan/L=Michigan/O=MicroTouch/OU=MicroTouch/CN=Mircotouch/emailAddress=max.chen@microtouch.com’
./development/tools/make_key media ‘/C=US/ST=Michigan/L=Michigan/O=MicroTouch/OU=MicroTouch/CN=Mircotouch/emailAddress=max.chen@microtouch.com’
./development/tools/make_key shared ‘/C=US/ST=Michi
