| Signs all the APK files in a target-files zipfile, producing a new |
| target-files zip. |
| |
| Usage: sign_target_files_apks [flags] input_target_files output_target_files |
| |
| -e (--extra_apks) <name,name,...=key> |
| Add extra APK name/key pairs as though they appeared in |
| apkcerts.txt (so mappings specified by -k and -d are applied). |
| Keys specified in -e override any value for that app contained |
| in the apkcerts.txt file. Option may be repeated to give |
| multiple extra packages. |
| |
| -k (--key_mapping) <src_key=dest_key> |
| Add a mapping from the key name as specified in apkcerts.txt (the |
| src_key) to the real key you wish to sign the package with |
| (dest_key). Option may be repeated to give multiple key |
| mappings. |
| |
| -d (--default_key_mappings) <dir> |
| Set up the following key mappings: |
| |
| $devkey/devkey ==> $dir/releasekey |
| $devkey/testkey ==> $dir/releasekey |
| $devkey/media ==> $dir/media |
| $devkey/shared ==> $dir/shared |
| $devkey/platform ==> $dir/platform |
| |
| where $devkey is the directory part of the value of |
| default_system_dev_certificate from the input target-files's |
| META/misc_info.txt. (Defaulting to "build/target/product/security" |
| if the value is not present in misc_info. |
| |
| -d and -k options are added to the set of mappings in the order |
| in which they appear on the command line. |
| |
| -o (--replace_ota_keys) |
| Replace the certificate (public key) used by OTA package verification |
| with the ones specified in the input target_files zip (in the |
| META/otakeys.txt file). Key remapping (-k and -d) is performed on the |
| keys. For A/B devices, the payload verification key will be replaced |
| as well. If there're multiple OTA keys, only the first one will be used |
| for payload verification. |
| |
| -t (--tag_changes) <+tag>,<-tag>,... |
| Comma-separated list of changes to make to the set of tags (in |
| the last component of the build fingerprint). Prefix each with |
| '+' or '-' to indicate whether that tag should be added or |
| removed. Changes are processed in the order they appear. |
| Default value is "-test-keys,-dev-keys,+release-keys". |
| |
| --replace_verity_private_key <key> |
| Replace the private key used for verity signing. It expects a filename |
| WITHOUT the extension (e.g. verity_key). |
| |
| --replace_verity_public_key <key> |
| Replace the certificate (public key) used for verity verification. The |
| key file replaces the one at BOOT/RAMDISK/verity_key (or ROOT/verity_key |
| for devices using system_root_image). It expects the key filename WITH |
| the extension (e.g. verity_key.pub). |
| |
| --replace_verity_keyid <path_to_X509_PEM_cert_file> |
| Replace the veritykeyid in BOOT/cmdline of input_target_file_zip |
| with keyid of the cert pointed by <path_to_X509_PEM_cert_file>. |
