1.使用platform密鑰對(duì)apk進(jìn)行簽名

?

1.1.進(jìn)入<Android_Source_Path>/build/target/product/security,找到【platform.pk8】和【platform.x509.pem】系統(tǒng)密鑰。
1.2.進(jìn)入<Android_Source_Path>/build/tools/signapk找到SignApk.java，執(zhí)行javac編譯成SignApk.class
1.3.運(yùn)行命令java com.android.signapk.SignApk platform.x509.pem platform.pk8 input.apk output.apk

至此，完畢。

2. 對(duì)1的補(bǔ)充：

<Android_Source_Path>/build/target/product/security下有多對(duì)密鑰，具體例如以下：

The following commands were used to generate the test key pairs:

? development/tools/make_key testkey? '/C=US/ST=California/L=Mountain View/O=Android/OU=Android/CN=Android/emailAddress=android@android.com'
? development/tools/make_key platform '/C=US/ST=California/L=Mountain View/O=Android/OU=Android/CN=Android/emailAddress=android@android.com'
? development/tools/make_key shared?? '/C=US/ST=California/L=Mountain View/O=Android/OU=Android/CN=Android/emailAddress=android@android.com'
? development/tools/make_key media??? '/C=US/ST=California/L=Mountain View/O=Android/OU=Android/CN=Android/emailAddress=android@android.com'

The following standard test keys are currently included:

testkey -- a generic key for packages that do not otherwise specify a key.
platform -- a test key for packages that are part of the core platform.
shared -- a test key for things that are shared in the home/contacts process.
media -- a test key for packages that are part of the media/download system.

These test keys are used strictly in development, and should never be assumed
to convey any sort of validity.? When $BUILD_SECURE=true, the code should not
honor these keys in any context.


signing using the openssl commandline (for boot/system images)
--------------------------------------------------------------

1. convert pk8 format key to pem format
?? % openssl pkcs8 -inform DER -nocrypt -in testkey.pk8 -out testkey.pem

2. create a signature using the pem format key
?? % openssl dgst -binary -sha1 -sign testkey.pem FILE > FILE.sig

extracting public keys for embedding
------------------------------------
it's a Java tool
but it generates C code
take a look at commands/recovery/Android.mk
you'll see it running $(HOST_OUT_JAVA_LIBRARIES)/dumpkey.jar

3.對(duì)3的補(bǔ)充：

在執(zhí)行第三步的命令前，請(qǐng)?jiān)谀惝?dāng)前的工作文件夾下新建例如以下結(jié)構(gòu)的文件夾:com.android.signapk，然后將第二步編譯生成的SignApk放入該文件夾下。或者也能夠?qū)ignApk.java的package聲明刪除后再執(zhí)行javac編譯。

?

命令java com.android.signapk.SignApk platform.x509.pem platform.pk8 input.apk output.apk

不單能夠?qū)pk文件進(jìn)行重簽名，也能夠?qū)θ康膠ip文件進(jìn)行重簽名，包含ROM文件。
