**AcroSuite Cipher** provides some RSA Cipher/Decipher **RESTful APIs,** they may be called from Web site, Server side and Native application. Of course, it is required to support **RESTful APIs** in HTTP/HTTPS. In the meantime, you are assumed to have some knowledge above **PKI/RSA**. You can find a lot of code snippet by Java/JavaScript/Node.js/C/C#/GO/Kotlin/Objective-C/PHP/Python/R/Powershell/Ruby/Swift/R/Shell in the following page. https://api.rakuten.net/AcroChannel/api/acrosuite-cipher Here, I paste my HTML/JavaScript(jQuery) for you to have a test. The whole test page is [here](https://mars.acrochannel.com/intro/en/suite_en_rakuten.html#cipher). https://mars.acrochannel.com/intro/en/suite_en_rakuten.html#cipher ##HTML ```
