1、查看 keystore

$ keytool -list -keystore debug.keystore

结果：

Keystore type: JKS

Keystore provider: SUN

Your keystore contains 1 entry

androiddebugkey, Mar 21, 2013, PrivateKeyEntry,

Certificate fingerprint (MD5): E0:F4:90:EE:CD:77:17:0E:B8:C4:AC:64:B2:F6:FC:83

2、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：

Issuer: CN=Android Debug, O=Android, C=US
