使用SHA256withRSA而不是SHA1withRSA生成签名

Question

我一直在尝试生成sha1键,以便在windows7上使用谷歌地图v2.根据google docs运行以下命令:

keytool -list -v -keystore "C:\Users\your_user_name\.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android

输出应与此类似(https://developers.google.com/maps/documentation/android/start#getting_the_google_maps_android_api_v2)

 Alias name: androiddebugkey
 Creation date: Jan 01, 2013
 Entry type: PrivateKeyEntry

 Certificate fingerprints:

      Signature algorithm name: SHA1withRSA
      Version: 3 

我的输出:

    Alias name: androiddebugkey
    Creation date: 12-Jun-2013
    Entry type: PrivateKeyEntry
    Certificate chain length: 1
    Certificate[1]:
    Owner: CN=Android Debug, O=Android, C=US
    Issuer: CN=Android Debug, O=Android, C=US
    Serial number: 57376504

    Certificate fingerprints:

             SHA1: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
             Signature algorithm name: SHA256withRSA
             Version: 3    

   Extensions:

   #1: ObjectId: 2.5.29.14 Criticality=false
   SubjectKeyIdentifier [
   KeyIdentifier [
   0000: 5D 1C 48 72 D9 E2 F0 1A   12 CE 97 CC 1F DA DD F6  ].Hr............

   ]
   ]

但在我的情况下,输出类似,但除外.

Signature algorithm name:SHA256withRSA

有人能告诉我如何通过SHA1withRSA生成密钥.问这个问题的原因是我想在我的Android应用程序中使用谷歌地图v2.显示以下错误.我猜SHA256withRSA可能是造成这个错误的原因.我被困在授权失败的几天.如果有人可以帮助我真的很棒..谢谢..

Authorization failure.  Please see https://developers.google.com/maps/documentation/android/start for how to correctly set up the map.

您使用的是 JDK 1.7 吗？如果是，请对 keytool 使用以下参数：

-sigalg SHA1WithRSA -digestalg SHA1

-v使用 JDK 1.6，您可以尝试交换和的位置-list（我知道，听起来很奇怪）以获得所有可能的算法（MD5、SHA1、SHA256）

keytool -v -list -keystore "C:\Users\your_user_name.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android
