| 24 | Add extra APK name/key pairs as though they appeared in |

| 26 | Keys specified in -e override any value for that app contained |
| 27 | in the apkcerts.txt file. Option may be repeated to give |
| 28 | multiple extra packages. |
Doug Zongker | eef3944 | 2009-04-02 12:14:19 -0700 | [diff] [blame] | 29 | |
| 30 | -k (--key_mapping) <src_key=dest_key> |
| 31 | Add a mapping from the key name as specified in apkcerts.txt (the |
| 32 | src_key) to the real key you wish to sign the package with |
| 33 | (dest_key). Option may be repeated to give multiple key |
| 34 | mappings. |
| 35 | |
| 36 | -d (--default_key_mappings) <dir> |
| 37 | Set up the following key mappings: |

| 42 | $devkey/shared ==> $dir/shared |
| 43 | $devkey/platform ==> $dir/platform |
| 44 | |
| 45 | where $devkey is the directory part of the value of |
| 46 | default_system_dev_certificate from the input target-files's |
| 47 | META/misc_info.txt. (Defaulting to "build/target/product/security" |
| 48 | if the value is not present in misc_info. |
Doug Zongker | eef3944 | 2009-04-02 12:14:19 -0700 | [diff] [blame] | 49 | |
| 50 | -d and -k options are added to the set of mappings in the order |
| 51 | in which they appear on the command line. |

Tao Bao | a80ed22 | 2016-06-16 14:41:24 -0700 | [diff] [blame] | 54 | Replace the certificate (public key) used by OTA package verification |
| 55 | with the ones specified in the input target_files zip (in the |
| 56 | META/otakeys.txt file). Key remapping (-k and -d) is performed on the |
| 57 | keys. For A/B devices, the payload verification key will be replaced |
| 58 | as well. If there're multiple OTA keys, only the first one will be used |
| 59 | for payload verification. |

| 64 | '+' or '-' to indicate whether that tag should be added or |
| 65 | removed. Changes are processed in the order they appear. |
Doug Zongker | 831840e | 2011-09-22 10:28:04 -0700 | [diff] [blame] | 66 | Default value is "-test-keys,-dev-keys,+release-keys". |

| 70 | WITHOUT the extension (e.g. verity_key). |
| 71 | |
| 72 | --replace_verity_public_key <key> |
| 73 | Replace the certificate (public key) used for verity verification. The |
| 74 | key file replaces the one at BOOT/RAMDISK/verity_key (or ROOT/verity_key |
| 75 | for devices using system_root_image). It expects the key filename WITH |
| 76 | the extension (e.g. verity_key.pub). |

| 84 | Use the specified algorithm (e.g. SHA256_RSA4096) and the key to AVB-sign |
| 85 | the specified image. Otherwise it uses the existing values in info dict. |
| 86 | |
| 87 | --avb_{boot,system,vendor,dtbo,vbmeta}_extra_args <args> |
| 88 | Specify any additional args that are needed to AVB-sign the image |
| 89 | (e.g. "--signing_helper /path/to/helper"). The args will be appended to |
| 90 | the existing ones in info dict. |
