我在使用keytool获取SHA1证书时遇到问题
[英]I'm having trouble getting SHA1 certificate with keytool
问题描述
I'm trying to find the SHA1 hash of my signature key store on macos sierra using the following comand: 
我正在尝试使用以下命令在macos sierra上找到我的签名密钥库的SHA1哈希：
keytool -exportcert -alias androiddebugkey -keystore $HOME/.android/debug.keystore -list -v -storepass android
The result looks like below: 结果如下所示：
Alias name: androiddebugkey
Date of creation: Oct 25, 2017
Input Type: PrivateKeyEntry
Length of certificate chain: 1
Certificate [1]:
keytool error: java.util.IllegalFormatConversionException: d != java.lang.String java.util.IllegalFormatConversionException: d != java.lang.String at java.base/java.util.Formatter$FormatSpecifier.failConversion(Formatter.java:4331) at java.base/java.util.Formatter$FormatSpecifier.printInteger(Formatter.java:2846) at java.base/java.util.Formatter$FormatSpecifier.print(Formatter.java:2800) at java.base/java.util.Formatter.format(Formatter.java:2581) at java.base/java.util.Formatter.format(Formatter.java:2517) at java.base/java.lang.String.format(String.java:2747) at java.base/sun.security.tools.keytool.Main.withWeak(Main.java:3151) at java.base/sun.security.tools.keytool.Main.printX509Cert(Main.java:3182) at java.base/sun.security.tools.keytool.Main.doPrintEntry(Main.java:1995) at java.base/sun.security.tools.keytool.Main.doCommands(Main.java:1212) at java.base/sun.security.tools.keytool.Main.run(Main.java:397) at java.base/sun.security.tools.keytool.Main.main(Main.java:390)
As far as I can see the command is working, it is not a problem with the file nor with password, it seems to me an internal error in java, is it missing some java package? 据我所知，该命令正在运行，它不是文件的问题，也不是密码，在我看来java中的一个内部错误，它是否缺少一些java包？ I am using Java SDK 9.0.1 我正在使用Java SDK 9.0.1

I found that the problem comes from latest version of Keytool in JDK8.151 and JDK9 . 我发现问题来自JDK8.151和JDK9最新版Keytool。 By default keytool use system default language and that seems to do not properly work anymore on some languages (in my case French). 默认情况下， keytool使用系统默认语言，并且似乎在某些语言上不再正常工作（在我的例子中是法语）。
It was enough to force output in english by using the parameter -J-Duser.language=en 使用参数-J-Duser.language=en强制输出英文输出就足够了
So try using this command line instead: 因此，请尝试使用此命令行：
keytool -J-Duser.language=en -exportcert -alias androiddebugkey -keystore $HOME/.android/debug.keystore -list -v -storepass android
