Does Chrome support Java? Using Java in Chrome is a little bit tricky at this moment.
NPAPI was required to enable Java applets, but since 24th of November 2014, NPAPI was disabled by default.
Sun java free download - Java Runtime Environment (JRE), JadeIDE for Java, Java SE Development Kit 8, and many more programs. Enter to Search. My Profile Logout. Finishes the MAC operation. A call to this method resets this Mac object to the state it was in when previously initialized via a call to init(Key) or init(Key, AlgorithmParameterSpec).That is, the object is reset and available to generate another MAC from the same key, if desired, via new calls to update and doFinal. (In order to reuse this Mac object with a different key, it must be.
Since April 2015 NPAPI plugins were unpublished from Chrome Web Store.
Between this period you could enable it in settings:
But currently it’s not possible anymore, so you cannot just download Java for Chrome and make it running.
So as I mentioned nowadays you should use little tricks…
But first of all, you need to install Java on your PC.
Install Java For Chrome on Windows
How to use Java with Chrome steps:
Install IE Tab chrome extension (it emulates Internet Explorer under your Chrome browser and allows to run Java and Silverlight).
You’ll find its icon “e” in the right top corner. Click it and follow installation steps (run ietabhelper.exe).
You’ll find its icon “e” in the right top corner. Click it and follow installation steps (run ietabhelper.exe).
After that, a new tab will be opened and you’ll be allowed to use new IE Tab search line.
Verify Java version here https://www.java.com/en/download/installed.jsp
Press a “Verify Java version” button.
You should confirm that you want to run Java detection application.
and see that Java is running.
Not native Java support, but it’s better than nothing.
Install Java For Chrome on MacOs and Linux
Tab IT plugin doesn’t support MacOs and Linux, that’s why we gonna use Test IE plugin.
The problem is you have to pay, but they give you a free trial to test.
So when you activate this Chrome extension you will be redirected to a homepage:
Press a FREE TRIAL in the top right corner and register.
Then you’ll be redirected to a list of available OS and browsers.
I recommend taking FireFox under 52 version because FF after 52 partially supports Java.
After that FF browser will be opened on your tab.
Go to Java verification page to be sure that it’s running.
Press a button and browser will ask you to allow Java:
Then it will ask you: “do you really want to run Java detection application?”. Press “Run”.
And at the end, it will say that your current Java version is 8 Update 151.
That means, Java is running and you can use whatever you want.

Sun Java Virtual Machine 1.4
- All Implemented Interfaces:
- Cloneable
This class provides the functionality of a 'Message Authentication Code' (MAC) algorithm.A MAC provides a way to check the integrity of information transmitted over or stored in an unreliable medium, based on a secret key. Typically, message authentication codes are used between two parties that share a secret key in order to validate information transmitted between these parties.A MAC mechanism that is based on cryptographic hash functions is referred to as HMAC. HMAC can be used with any cryptographic hash function, e.g., SHA256 or SHA384, in combination with a secret shared key. HMAC is specified in RFC 2104.Every implementation of the Java platform is required to support the following standardMac
algorithms:- HmacMD5
- HmacSHA1
- HmacSHA256
- Since:
- 1.4

Method Detail
getAlgorithm
Returns the algorithm name of thisMac
object.This is the same name that was specified in one of thegetInstance
calls that created thisMac
object.- Returns:
- the algorithm name of this
Mac
object.
getInstance
Returns aMac
object that implements the specified MAC algorithm.This method traverses the list of registered security Providers, starting with the most preferred Provider. A new Mac object encapsulating the MacSpi implementation from the first Provider that supports the specified algorithm is returned.Note that the list of registered providers may be retrieved via theSecurity.getProviders()
method.- Parameters:
algorithm
- the standard name of the requested MAC algorithm. See the Mac section in the Java Cryptography Architecture Standard Algorithm Name Documentation for information about standard algorithm names.- Returns:
- the new
Mac
object. - Throws:
NoSuchAlgorithmException
- if no Provider supports a MacSpi implementation for the specified algorithm.- See Also:
Provider
getInstance
Returns aMac
object that implements the specified MAC algorithm.A new Mac object encapsulating the MacSpi implementation from the specified provider is returned. The specified provider must be registered in the security provider list.Note that the list of registered providers may be retrieved via theSecurity.getProviders()
method.- Parameters:
algorithm
