Android签名相关知识整理
不止一次有用到Android签名相关的知识，每次都几乎从零开始在Google上搜索找，不想在继续这样了，找了个时间好好整理了一下自己用到的一些碎片知识，于是乎放到这里，一是备忘，二是帮助别人。
从APK文件中获取签名信息
使用方法
1 | keytool -list -printcert -jarfile your_apk_file |
|---|
输出信息
- 签名Owner,Issuer等信息
- 签名的fingerprints,如md5及sha1等值
- 签名有效期等信息
示例效果
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | 16:29 $ keytool -list -printcert -jarfile akoi_1.2.apk Signer #1: Signature: Owner: CN=Andrew Wallace, OU=droidyue.com, O=droidyue.com, L=Beijing, ST=Beijing, C=86 Issuer: CN=Andrew Wallace, OU=droidyue.com, O=droidyue.com, L=Beijing, ST=Beijing, C=86 Serial number: 11a8a4a3 Valid from: Tue Feb 10 18:07:43 CST 2015 until: Sun Jun 13 18:07:43 CST 3013 Certificate fingerprints: MD5: 46:C5:BE:EF:B5:C9:00:E1:FA:42:50:50:57:54:CA:15 SHA1: C1:14:5D:0A:C2:BF:F6:06:43:20:AE:2C:07:12:97:58:C2:1B:39:D1 SHA256: 0E:88:7D:C2:4C:D6:84:A7:58:D4:24:1E:9D:38:F9:05:98:1E:B2:A2:D7:CB:0F:81:74:60:5B:38:89:FF:21:1C Signature algorithm name: SHA256withRSA Version: 3 |

从签名文件中获取签名信息
使用方法
1 | keytool -list -v -keystore your_kestore_file |
|---|
注意，上述命令执行后，会提示输入密码，其实输入错误也没有关系，不影响结果。
输出信息
- 签名Owner,Issuer等信息
- 签名的fingerprints,如md5及sha1等值
- 签名有效期等信息

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 | Keystore type: JKS Keystore provider: SUN Your keystore contains 1 entry Alias name: droidyue.com Creation date: Feb 10, 2015 Entry type: PrivateKeyEntry Certificate chain length: 1 Certificate[1]: Owner: CN=Andrew Wallace, OU=droidyue.com, O=droidyue.com, L=Beijing, ST=Beijing, C=86 Issuer: CN=Andrew Wallace, OU=droidyue.com, O=droidyue.com, L=Beijing, ST=Beijing, C=86 Serial number: 11a8a4a3 Valid from: Tue Feb 10 18:07:43 CST 2015 until: Sun Jun 13 18:07:43 CST 3013 Certificate fingerprints: MD5: 46:C5:BE:EF:B5:C9:00:E1:FA:42:50:50:57:54:CA:15 SHA1: C1:14:5D:0A:C2:BF:F6:06:43:20:AE:2C:07:12:97:58:C2:1B:39:D1 SHA256: 0E:88:7D:C2:4C:D6:84:A7:58:D4:24:1E:9D:38:F9:05:98:1E:B2:A2:D7:CB:0F:81:74:60:5B:38:89:FF:21:1C Signature algorithm name: SHA256withRSA Version: 3 |

重新签名APK
在没有源码情况下，我们就能对apk进行更换签名。
脚本
使用方法
1 | bash signapk.sh your_apk_file your_keystore_file keystore_pass keystore_alias |
|---|
示例效果
1 2 3 4 5 6 7 8 9 10 11 12 13 | 16:57 $ bash signapk.sh weixin6313android740.apk ~/Documents/baidu_disk/百度云同步盘/droidapp/mykiki 123456 droidyue.com param1 weixin6313android740.apk param2 /Users/androidyue/Documents/droidapp/mykiki param3 123456 param4 droidyue.com deleting: META-INF/MANIFEST.MF deleting: META-INF/DROIDYUE.SF deleting: META-INF/DROIDYUE.RSA adding: META-INF/MANIFEST.MF adding: META-INF/DROIDYUE.SF adding: META-INF/DROIDYUE.RSA ...... Verification succesful |
|---|
生成的文件会放在当前目录，其文件名相对输入文件，增加了signed_前缀，比如对weixin6313android740.apk进行上述操作得到的输出文件是signed_weixin6313android740.apk
Gradle build生成签名APK
想要在执行gradle build时生成指定签名的apk，需要在build.gradle中如下修改
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 | android { signingConfigs { release { storeFile file("myrelease.keystore") storePassword "********" keyAlias "******" keyPassword "******" } } buildTypes { release { signingConfig signingConfigs.release } } } |
