I am developing a web application to encrypt some texts with java 6.
The encrypted that I have to do is a AES (Rijndael) in CBC mode with PKCS7 padding and a 128-bit key.
I saw an article that explains how to encrypt in the same way I have to do, but with PKCS5 padding.
The link of the article is here:
I change
private final static String cI = "AES/CBC/PKCS5Padding";
To
private final static String cI = "AES/CBC/PKCS7Padding";
But Java couldn't find a provider for this.
Could someone tell me how I have to do?
Java only provides PKCS#5 padding, but it is the same as PKCS#7 padding. See this question on Crypto.SE:
What is the difference between PKCS#5 padding and PKCS#7 padding
They are interchangeable for the common block ciphers like AES and DES.
