RSA / NONE / PKCS1Padding给出错误为java.security.NoSuchAlgorithmException [英] RSA/NONE/PKCS1Padding giving error as java.security.NoSuchAlgorithmException

问题描述

密码RSACipher = Cipher.getInstance（RSA / None / PKCS1Padding ）;

这给我例外：

java.security.NoSuchAlgorithmException：找不到任何支持RSA /无/ PKCS1Padding的提供者

感谢您的帮助。

解决方案

尝试RSA / ECB / PKCS1Padding在Oracle或Open JDK中运行。使用RSA进行加密的块密码模式并不太有意义，但并不是所有算法名称都是Java SE提供者中的逻辑。

Bouncy Castle Libraries支持RSA /无/ PKCS1Padding。所以也许代码是为Bouncy或Android编写的。

I am using "RSA/None/PKCS1Padding" as :

Cipher RSACipher = Cipher.getInstance("RSA/None/PKCS1Padding");

This gives me exception as :

java.security.NoSuchAlgorithmException: Cannot find any provider supporting RSA/None/PKCS1Padding

Thanks for help.

解决方案

Try "RSA/ECB/PKCS1Padding" instead if you are running in an Oracle or Open JDK. It does not make too much sense to use a block cipher mode of encryption with RSA, but not all algorithm names are logical within the Java SE providers.

The Bouncy Castle Libraries support "RSA/None/PKCS1Padding" though. So maybe the code was written for Bouncy or Android.
