如何从 Java 的 keytool (而不仅仅是 SHA-1)获得 MD5指纹？

因为我想在我的应用程序中使用 Google 地图，所以我需要调试证书的 MD5指纹:

(在这里，我在 bin 文件夹中从 C: Document and Settings Administration. android 复制了 debug. keystore 文件)

C:\Program Files\Java\jdk1.7.0\bin>keytool -list -alias androiddebugkey -keystore debug.keystore -storepass android -keypass android

但结果如下:

androiddebugkey, May 27, 2011, PrivateKeyEntry,Certificate fingerprint (SHA1): "some code"

然而，这并不能得到 MAP API 密钥。 SHA1和 MD5是一样的吗？

我应该怎样做才能获得 MD5证书？

copy ' debug.keystore ' file to c:\ or Some folder

you try going c:\Program Files\Java\jdk1.6.25\bin folder and input

c:\Program Files\Java\jdk1.6.25\bin>keytool -list -keystore c:\debug.keystore

password is 'android'

With JDK 1.7 installed, keytool always outputs by default SHA1 fingerprint, not MD5. you can get the MD5 Certificate by adding -v option.

use the following code:-

C:\Program Files\Java\jdk1.7.0\bin>keytool -v -list -alias
androiddebugkey -keystore debug.keystore -storepass android -keypass android

it will output MD5 certificate as well.

It's not true that JDK 1.7 keytool ALWAYS return SHA1 fingerprint. Look there to solve the problem instead of downgrade your JDK: http://code.google.com/p/android/issues/detail?id=19035#makechanges

If you are using jdk 7:

Use -v option.

To get MD5 value and SHA1...etc fallow this below:

Before this dont forget to copy the debug.keystore to a folder Androidkeystore like that created in C drive.

C:\Program Files\Java\jdk1.7.0_05\bin>keytool -v -list -keystore C:\Androidkeyst
ore\debug.keystore

it asks here.. Enter keystore password: android

enter you got here MD5 & SHA1..etc

Keystore type: JKS
Keystore provider: SUN


Your keystore contains ? entry


Alias name: androiddebugkey
Creation date: ?? ???, ????
Entry type: PrivateKeyEntry
Certificate chain length: 1
Certificate[?]:
Owner: CN=Android Debug, O=Android, C=US
Issuer: CN=Android Debug, O=Android, C=US
Serial number: 67b6344b
Valid from: Mon Jun 18 20:33:56 IST 2012 until: Wed Jun 11 20:33:56 IST 2042
Certificate fingerprints:
MD5:  C2:61:51:3E:BC:C8:0C:DB:75:B6:E7:C4:90:AD:91:39
SHA1: CD:5E:8A:0F:4E:0F:2E:FD:92:5E:5E:4R:CF:F8:44:33:2C:8C:B8:97
SHA256: B5:BF:75:60:DB:62:09:49:F1:38:CH:49:18:22:18:95:03:C9:5C:14:F6:
B0:F4:21:D2:19:B8:FF:38:D2:B9:FD
Signature algorithm name: SHA256withRSA

NOTE: if there are any spaces in the directory path you MUST enclose it in quotes. e.g. use this format:

-keystore "C:\Users\Your Name\.android\debug.keystore"

add -v

right after keytool and before -list

keytool -v -list

The -v flag gives the SHA1 certification as well. Without that flag you only get the MD5 fingerprint.

I have solved the problem in Windows 8 by opening the Command Prompt (Admin), then type:

C:\Program Files (x86)\Java\jre7\bin>keytool -v -list -keystore C:\<Your Path>\<Your Keystore>

After that, simply go to https://code.google.com/apis/console/

As they changed to a new interface, you have to go to the APIs & auth tab on the left side, then go to Registered Apps, select your existing API key to replace it or create a new one, using the SHA1 code generated previously.

That's how I got it working.

Simply export your project using your keystore in eclipse and in the last step you will get both SHA-1 and MD-5..

Look at this question for more details.

The easiest way to get SHA 1,MD 5 is to click on Gradle in the upper hand right side near the corner of the screen of Android Studio. Then click on the name of the app(e.g android123(root): it should appear like this). After that, you will find a subfolder named android and clicking on it go for the signingReport.It should run in the console and should show you the SHA 1,MD 5. Hope it helps.

Hello in the year 2021.

The keytool of JDK 8 and newer does not print MD5 anymore, even if you try the standard suggestion to add the "-v" option to the "keygen -list" command.

I guess MD5 is no more considered secure enough and has been removed.

At the same time there are still places like Amazon "Security Profile Management" for LWA etc. requiring you to submit the MD5 signature of your certificate.

Here is a command which will deliver it (use the password "android" for the Android Studio keystore):

keytool -exportcert -alias androiddebugkey -keystore ~/.android/debug.keystore | \
openssl dgst -md5

And if you want to have colon character inbetween, then add the following "sed" command:

keytool -exportcert -alias androiddebugkey -keystore ~/.android/debug.keystore | \
openssl dgst -md5 | \
sed 's/[a-fA-F0-9][a-fA-F0-9]/&:/g; s/:$//'

The above command works on Linux, macOS and even Windows (in git bash):
