How to encrypt data using AES in Java

问题:

I wish to encrypt a piece of data using AES (cbc) in java , I Want to use my own IV, which I have held in a byte array and my own key held in a byte array.

How would I go about doing this?

I'm searching for it to find tutorials on this topic.

This is probably the best guide that I've found on the subject. It explains the basics, one concept at a time, in simple terms.

Formally it encrypts the string into unreadable format. Use same code to decrypt.

ENCRYPT:

    String s1="arshad";

    char[] s2=s1.toCharArray();
    int s3= s2.length;
    System.out.println(s3);
   int i=0;
   // for(int j=0;j<s3;j++)
          //  System.out.println(s2[j]);

       for(i=0;i<((s3)/2);i++)
        {
            char z,f=10;
            z=(char) (s2[i] * f);
            s2[i]=s2[(s3-1)-i];
            s2[(s3-1)-i]=z;
            String b=new String(s2);
            print(b);
        }
