Hello all,

I have been trying to generate an x509 certificate and sign it with my private key but I could not. I found some codes online but have problems not working properly. Also, most of them are deprecated.

I appreciate the help and support

Thanks Sandeep but I have tried the code in the link you posted and it has a problem. Have you tried it? if yes, I would benefit a lot if you send me the whole project including all the libraries.

Regards

That is not the way it works. We do not provide code. We are developers ourselves, we code for money.

What is the exception/ error? have you just c&p'd the code/followed the link at the end of the tutorial or did you actually read the tutorial?
It's not that hard to create X509 certificates.

Hello

Yes I did read the whole tutorial but the line that had a problem was this
certGen.setSerialNumber(new DERInteger(BigInteger.valueOf(System.currentTimeMillis())));

I only asked for a push not for a complete code.

That's simply it.

list and map

on what criteria we will decide whether to use map or list?

Richard MacCutchan31-Jan-13 22:46

31-Jan-13 22:46

It depends what you want to do with the information you are processing. The List[^] is just a simple list of values, whereas a Map[^] has keys to values for fast access.

i have one confusion that when we declare a list as below

List lt = new Arraylist();

Then in that case what value it can store i.e same type of value or it is capable of storing any type of variables or objects.

The List can store any type of object, but it does not make sense to store different types in the same list.

Many things you need to know,

1) IF you store just one object, use List, if you have two object key and value use Map.
2) List is ordered, your objects will be stored in the order on which they are inserted, Map is not ordered, unless you use sorted ones.

There is no way for a general language to be secure.
That is because how applications are implemented as well as the business domain and even where they run impact their security.
