问题
I am trying to decrypt the data using RSA Algorithm. While doing the decryption, I am getting an exception.That is,
java.security.NoSuchAlgorithmException: Cannot find any provider supporting RSA/ECB/PKCS5Padding
at javax.crypto.Cipher.getInstance(DashoA13*..)
How to solve this exception? Currently, I am using java version "1.6.0_26".
回答1:
It's a typo. The correct name for RSA with PKCS #1 v1.5 padding is "RSA/ECB/PKCS1Padding". Generally, it is a good idea to compare with a list of available algorithms. E.g. this question contains some ways to print such a list.
(And of course using OAEP instead of v1.5 padding would be preferable, especially if your main field is not cryptography).
回答2:
The error means that the library you use cna't decrypt the data because there isn't an algorithm in the Lib which decrypts RSA. You can use a library like Bouncy Calste or GNU Crypto to decrypt data using RSA. There are plenty of samples how to do this on the web.
