| The following commands were used to generate the test key pair: |
| |
| openssl genrsa -3 -out testkey.pem 2048 |
| |
| openssl req -new -x509 -key testkey.pem -out testkey.x509.pem -days 10000 \ |
| -subj '/C=US/ST=California/L=Mountain View/O=Android/OU=Android/CN=Android/[email protected]' |
| |
| openssl pkcs8 -in testkey.pem -topk8 -outform DER -out testkey.pk8 -nocrypt |
| |
| Alternatively you can use the "mkkey.sh" command included in this directory. |
| |
| 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 |
