Android签名修改

签名文件存放目录

/build/target/product/security

参考文件

/build/target/product/security/README

操作流程

替换文件

示例代码

./development/tools/make_key build/target/product/security/shared '/C=CN/ST=ShenZhen/L=ShenZhen/O=momxmo/OU=mo/CN=www.momxmo.com/emailAddress=test@126.com'

注意，不要设置密码，直接回车

verity_key文件需要多一步生成

先生成 generate_verity_key

make generate_verity_key

大概是等效

 mmm system/extras/verity/

然后

out/host/linux-x86/bin/generate_verity_key -convert veritykey.x509.pem verity_key

最后拷贝veritykey.pk8，veritykey.x509.pem，verity_key.pub 至 build/target/product/security/ 目录，将其重命名: verity.pk8， verity.x509.pem，verity_key 。

修改配置

1.修改/build/core/config.mk文件

DEFAULT_SYSTEM_DEV_CERTIFICATE := build/target/product/security/releasekey

2.修改/build/core/Makefile.mk文件

ifeq ($(DEFAULT_SYSTEM_DEV_CERTIFICATE),build/target/product/security/releasekey)  
    BUILD_VERSION_TAGS += release-keys 

3.修改system/sepolicy/private/keys.conf 和 system/sepolicy/prebuilts/api/{apilevel}/private/keys.conf文件
