查看APK的签名的方法

跳转原文 1、查看 keystore $ keytool -list -keystore debug.keystore 结果：Keystore type: JKSKeystore provider: SUNYour keystore contains 1 entryandroiddebugkey, Mar 21, 2013, PrivateKeyEntry, Certificate fingerprint (MD5): E0:F4:90:EE:CD:77:17:0E:B8:C4:AC:64:B2:F6:FC:832、查看三方应用或是系统应用签名
用winrar打开待查看的apk，将其中META-INF文件夹解压出来，得到其中的CERT.RSA文件
$ keytool -printcert -file META-INF/CERT.RSA结果：
Owner: CN=Android Debug, O=Android, C=USIssuer: CN=Android Debug, O=Android, C=USSerial number: 514ab2e1Valid from: Thu Mar 21 15:12:33 CST 2013 until: Sat Mar 14 15:12:33 CST 2043Certificate fingerprints:MD5: E0:F4:90:EE:CD:77:17:0E:B8:C4:AC:64:B2:F6:FC:83SHA1: 7F:E5:11:D8:37:4F:DA:D7:75:EA:A5:8C:47:06:85:95:6D:1D:3F:2BSignature algorithm name: SHA1withRSAVersion: 3
3、给空白包签名 jarsigner -verbose -keystore [keystorePath] -signedjar [apkOut] [apkIn] [alias]
jarsigner命令格式：-verbose输出详细信息 -keystore密钥库位置 -signedjar要生成的文件 要签名的文件 密钥库文件keystorePath参数代表keyStore的绝对路径，如D:\keystoreapkOut参数代表签名后的apk路径，如D:\signed.apkapkin参数代表在腾讯应用中心下载的未签名apk，默认名称为tap_unsign.apkalias参数代表签名用的alias名称（创建keyStore时所填写），如timdong
$ jarsigner -verbose -keystore debug.keystore -signedjar test2.apk tap_unsign1.apk timdongEnter Passphrase for keystore: adding: META-INF/MANIFEST.MF adding: META-INF/ANDROIDD.SF adding: META-INF/ANDROIDD.RSA signing: res/drawable/ic_launcher.png signing: res/layout/main.xml signing: AndroidManifest.xml signing: resources.arsc signing: classes.dex
