Where is the Keytool application?

Question

I need to use mapview control in android and I can't seem to understand how to run keytool. Is it installed with eclipse? I can't seem to find a download link.

Thanks

keytool is part of the standard java distribution.

In a windows 64-bit machine, you would normally find the jdk at

C:\Program Files\Java\jdk1.8.0_121\bin

It is used for managing keys and certificates you can sign things with, in your case, probably a jar file.

If you provide more details of what you need to do, we could probably give you a more specific answer.

Your link points to the Java 1.3 (very old!) documentation. The docs for the Java SE 6 version are here: http://download.oracle.com/javase/6/docs/technotes/tools/solaris/keytool.html – Jesper Jan 28 '11 at 16:01

@Amit if you have the JDK installed and added the `bin` folder of your JDK to the `PATH` you should be able to use the `keytool`. – Jesper Jan 28 '11 at 16:02

Funny, the question is "where", not "what", is keytool... why was this even accepted. – Zoomzoom May 12 '16 at 19:05

@Zoomzoom: Thought the same after ending up here. Edited the question to fix this. – Veverke Mar 01 '17 at 10:22
Installing entire JDK is not necessary if you need just keytool. It is sufficient to install JRE (Jave Runtime) - it is smaller than JDK (Java Development Kit) – VeganHunter Jul 24 '19 at 23:25

keytool is a tool to manage (public/private) security keys and certificates and store them in a Java KeyStore file (stored_file_name.jks).
It is provided with any standard JDK/JRE distributions.
You can find it under the following folder %JAVA_HOME%\bin.

`$JAVA_HOME/bin` for Linux and friends – clapsus Jul 30 '15 at 13:45
@evandrix When I open keytools.exe it keeps closing. – JayC Jan 23 '17 at 16:09
It's not meant to be opened, it's a command line tool (and should close as soon as it prints whatever it prints initially). – milosmns Feb 11 '18 at 16:20
Do not forget the double quotes, depending on your (Windows) configuration : `"%JAVA_HOME%\bin\keytool"` – SR_ Mar 11 '18 at 22:03

keytool is provided not only in JDK but also in JRE destribution which takes less disk space – VeganHunter Jul 24 '19 at 23:27

For me it turned out to be in c/Program Files/Java/jdk1.7.0_25/bin (Windows 8). A more general answer to this question is that it will most likely be in the bin sub directory of wherever your jdk is installed.

keytool it's a binary file into the JDK folder ... just add your JDK as environment variable by adding the following line

C:\Program Files\Java\jdk1.8.0_65\bin

It is in path/to/jdk/bin. Make sure that $JAVA_HOME is defined, and $JAVA_HOME/bin is added to $PATH, or else the 'keytool' command won't be recognized when called.

If you have java installed of course keytool is in there. What you need to do is to add it on your PATH variable.
