RSA / NONE / PKCS1Padding给出错误，如java.security.NoSuchAlgorithmException

Question

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.

Answer 1

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.
