Enable security functions like password encryption, digital signatures, secure random number generation, message authentication, Two Factor Authentication (2FA), and more with Java encryption libraries.


Encryption, decryption, and key generation are the three most crucial aspects of Java cryptography. Key-based data security can be enabled in two ways, using symmetric or asymmetric encryption algorithms, considering how secure the code needs to be. Moreover, developers can easily enable security functions directly into the code with the set of APIs available in the Java Cryptography Architecture (JCA). The JCA is the core of java encryption and decryption, hashing, secure random, and various other java cryptographic functions.


Check out the below list to find more trending Java encryption libraries for your applications:



Developers generally use java crypto libraries like Google Tink that help both encrypt and decrypt the data through simple and secure APIs.


Bouncy Castle is a popular Java cryptographic library that is used by developers to perform basic operations, such as encryption and digital signature.


Frequently used with Bouncy Castle, the Jasypt library helps enable basic encryption functions even if you don’t have deep cryptography know-how.

Judge Yvonne Gonzalez Rogers ordered that iOS apps must be allowed to support non Apple payment options in the Epic v. Apple case. In this case, Apple also scored a partial victory as the judge stopped short of calling it a monopoly. The judge also ordered Epic Games to pay Apple 30% of its revenue through the direct payment system. Epic is fighting a similar lawsuit against Google. Countries like South Korea have passed laws requiring Apple and Google to offer alternative payment systems to their users in the country. While the jury is still out on the Epic v. Apple case, it brings out two aspects. Is what is often referred to by developers as the "Apple Tax" of 30% indeed justified? For this reason, Epic launched the Epic Games Store to demonstrate that they could operate at a lower revenue cut of 12%. The second aspect is platform and payments interoperability. When platform interoperability becomes mandated or a global best practice, developers should be ready to bring in payment gateways of their choice. The kandi kit for App Store Payment Alternatives showcases the popular open source payment gateways such as Omnipay, Active Merchant, and CI Merchant and libraries available to connect with leading payment platforms such as Stripe, Braintree, and Razorpay.

The Trump Media and Technology Group is being investigated by Software Freedom Conservancy for non-compliance with copyleft licensing. The issue stems from President Donald Trump’s new social network, Truth Social appearing to be forked from Mastodon. While Mastodon is open source and available to use, it is licensed under Affero General Public License (or AGPLv3) that requires The Trump Media and Technology Group to share its source code with all who used the site. If they fail to do this within 30 days, their rights and permissions in the software are automatically and permanently terminated, making their platform inoperable. So if you are just a developer or a former POTUS, copyleft provisions apply to all. If you want to use open source, use kandi.openweaver.com. All libraries are matched to SPDX license definitions and highlighted clearly for appropriate use. Privacy, regulation, bias, and many other issues are weighing down popular social networks. Users are seeking self-hosted social platforms that can be governed by themselves. But do use them with the appropriate licenses. The kandi kit on Opensource Social Platforms lists popular opensource libraries that you can use to host private social channels.

One such library is bitcoinj. These open-source libraries have many advanced features implemented in Java and can be used by any JVM-compatible programming language, like Python. With these libraries, you can create components for building Bitcoin, Ethereum, Altcoin, Litecoin, and other such popular crypotocurrencies. You can also create and maintain the bitcoin wallet, integrate with popular crypto-exchanges, enable automated trading, and so on. You can use these to incorporate blockchain into a Java project, create wallets, and manage transactions between nodes, often without having to write your own integration code.

Below is our list of the 48 best Java cryptocurrency libraries that are open-source in 2021. XChange is a Java library of streamlined APIs for interaction with more than 60 Bitcoin and Altcoin exchanges. It has an MIT license and modular components with minimal dependency on third-party applications. Another library, bitcoin-wallet, is a wallet app for your Android device that works as a standalone Bitcoin payment platform with no centralized backend requirement. With this, you can integrate Bitcoin payments into your Android app. On the other hand, Best is an Apache 2.0 licensed enterprise-grade Ethereum client that is Java-based and MainNet compatible. Depending on your requirements, you can choose any of these open-source libraries for your project.

The hunting of animals has led to a decrease in their populations. Continuous hunting has a led a lot of animal species to go into extinction. Governments and scientists around the world have taken this into attention and started introducing a few laws by conducting a few surveys. Conducting surveys is a complicated task, especially without the help of technology. Some of these libraries can help you create customized forest survey applications.

Microk8s dashboard using nginx-ingress via http not working (Error: `no matches for kind "Ingress" in version "extensions/v1beta1"`)

Asked 2022-Apr-01 at 07:26

I have microk8s v1.22.2 running on Ubuntu 20.04.3 LTS.

Output from /etc/hosts:

1127.0.0.1 localhost
2127.0.1.1 main

Excerpt from microk8s status:

1127.0.0.1 localhost

7    ingress              # Ingress controller for external access
8    metrics-server       # K8s Metrics Server for API access to service metrics

it' due to the mismatch in the ingress API version.

You are running the v1.22.2 while API version in YAML is old.

Good example : https://kubernetes.io/docs/tasks/access-application-cluster/ingress-minikube/

you are using the older ingress API version in your YAML which is extensions/v1beta1.

You need to change this based on ingress version and K8s version you are running.

This is for version 1.19 in K8s and will work in 1.22 also

Example :

1127.0.0.1 localhost
2127.0.1.1 main

Microk8s dashboard using nginx-ingress via http not working (Error: `no matches for kind &quot;Ingress&quot; in version &quot;extensions/v1beta1&quot;`)

Asked 2022-Apr-01 at 07:26

I have microk8s v1.22.2 running on Ubuntu 20.04.3 LTS.

Output from /etc/hosts:

1127.0.0.1 localhost
2127.0.1.1 main

I want to expose the microk8s dashboard within my local network to access it through http://main/dashboard/

To do so, I did the following nano ingress.yaml:

1127.0.0.1 localhost
2127.0.1.1 main
3addons:
4  enabled:

Help would be much appreciated, thanks!

Update: @harsh-manvar pointed out a mismatch in the config version. I have rewritten ingress.yaml to a very stripped down version:

Applying this works. Also, the ingress rule gets created.
