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
-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.
--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>.
--avb_{boot,system,vendor,dtbo,vbmeta}_algorithm <algorithm>
--avb_{boot,system,vendor,dtbo,vbmeta}_key <key>
Use the specified algorithm (e.g. SHA256_RSA4096) and the key to AVB-sign
the specified image. Otherwise it uses the existing values in info dict.
--avb_{boot,system,vendor,dtbo,vbmeta}_extra_args <args>
Specify any additional args that are needed to AVB-sign the image
(e.g. "--signing_helper /path/to/helper"). The args will be appended to
the existing ones in info dict.
