Java keystore linux location

Which is the default location for keystore/truststore of Java applications?

I am writing an application that uses SSL. Hence, I have a dummy keystore and a dummy truststore I want to supply to my customer. Is there any default folder to put them inside my distribution? e.g. docs, lib, bin. etc. Where is usually the keystore put on the server and where is usually truststore put on the client? Thanks

In Java, according to the JSSE Reference Guide, there is no default for the keystore , the default for the truststore is «jssecacerts, if it exists. Otherwise, cacerts«.

A few applications use ~/.keystore as a default keystore, but this is not without problems (mainly because you might not want all the application run by the user to use that trust store).

I’d suggest using application-specific values that you bundle with your application instead, it would tend to be more applicable in general.

@user93353, it varies depending on the implementation. PKI talks about trust in various ways, but that can be «trust store», «trust anchors» or simply «trusted certificates». On Windows/schannel, you also get the «Trusted Root Certification Authorities store» and so on. AFAIK, there’s no uniform terminology.

More specifically, the default locations are /lib/security/jssecacerts and /lib/security/cacerts and you override it with the javax.net.ssl.trustStore system property.

One example, if one uses command «keytool» without provide -keystore , keytool will writes to ~/.keystore as default

Where is the Oracle java jdk keystore located?

The location of the keystore is jre/lib/security/cacerts. To display its contents, use the following command:

keytool -list -keystore java.home/jre/lib/security/cacerts -v 

Execute the following command to locate the JAVA_HOME.

sudo apt-get install galternatives 

And then run that program.

It appears that modifying the keystore is not necessary. Instead, you can make changes to the .policy file, which can be easily located at:

java.home/jre/lib/security/java.policy 

Naturally, if locating it remains a challenge, you can effortlessly obtain it using this directive.

Spring Java app not finding the keystore file

To load the file from the classpath, Spring enables the prefixing of the path with classpath: , for instance.

server.ssl.key-store : classpath:keystore.p12 

Alternatively, employing the symbol = as a delimiter for key/value pairs can also be utilized.

server.ssl.key-store = classpath:keystore.p12 

It’s important to note that only the left side of the value is trimmed, meaning that any trailing whitespace after the value is not allowed.

I faced the same problems and managed to resolve them. While I saved the keystore file in the directory of «src/main/resources/keystore.p12», it was located directly under «classes/» in the jar file. To tackle this issue, I came up with the following solution:

server.ssl.key-store=classpath:keystore.p12 

Based on the given information, it appears that your application is merely searching for the keystore.p12 file in the present directory.

Caused by: java.io.FileNotFoundException: /root/software/gimmememe/target/keystore.p12 (No such file or directory)

It’s probable that you have to inform Spring Boot about the file’s location within the jar.

Gradle and Maven will place the file located at src/main/resources at the root of the classpath. To inform the Spring Boot app about the file’s location on the classpath, you must specify it.

To ensure that the keystore is loaded from the archive’s classpath, it is necessary to assign classpath:keystore.p12 to server.ssl.key-store in order to inform Spring.

This fix is exemplified by another individual who faced a comparable issue.

How can I create a keystore?

To address the inquiry in the title, you can generate a keystore employing the Java Keytool utility that is included in a typical JDK package and can be found at %JAVA_HOME%in . On Windows machines, this is ordinarily situated at \ \ \ \ \ C:\Program\ Files\Java\jre7\bin\ \ \ \ .

To execute, navigate to the directory using a command window on Windows or a terminal on Linux.

keytool -genkey -v -keystore my-release-key.keystore -alias alias_name -keyalg RSA -keysize 2048 -validity 10000 

When creating a keystore with Keytool, you will be asked to provide passwords for both the keystore and key, as well as the Distinguished Name fields. Once you have entered this information, Keytool will generate the keystore as a file in your current directory, with a name specified by my-release-key.keystore . Both the keystore and key will be safeguarded by the passwords you chose. The keystore will contain only one key, which will remain valid for 10000 days. You can use the name alias_name in the future to refer to this keystore when you sign your application.

To find out further details on Keytool, refer to the documentation available at http://docs.oracle.com/javase/6/docs/technotes/tools/windows/keytool.html.

In my search for a way to create a .keystore using a single line command in the shell, I was determined to find a solution that would allow me to run it from any application. And fortunately, I found one!

echo y | keytool -genkeypair -dname "cn=Mark Jones, ou=JavaSoft, o=Sun, c=US" -alias business -keypass kpi135 -keystore /working/android.keystore -storepass ab987c -validity 20000 

• The dname serves as an exclusive identifier for the application within the .keystore. The person or organization that creates the .keystore can be referred to as «cn». The Organizational Unit responsible for the project can be a subdivision of the Organization that creates it. For example, «android.google.com» can be an Organizational Unit referred to as «ou». The Organization that owns the entire project can be referred to as «o», which is of a higher scope than the Organizational Unit («ou»). For example, «google.com» can be the Organization. The short code for the country can be referred to as «c». For instance, for the United States of America, the short code is «US».
• Alias refers to the identifier of an app as a single entity within the .keystore, even if multiple entities exist.
• Keypass» refers to the password used to secure a particular alias.
• The location for creating the file with the standard extension .ks is known as the keystore path.
• The password is used to secure the entire content of the .keystore and is known as the storepass.
• Duration of App’s validity will be determined by the number of days associated with the .keystore.

The file creation process was successful without requiring any additional console input. To learn more, refer to keytool — key and certificate management tool.
