I made this program it uses the RSA encryption algorithm to encrypt messages and decrypt messages

So people cant read them!!!!!!!

wheres is the source code??

@akukurt1 I haven't got the original code, I made it to encrypt images too but the problem is I made this program ages ago when I was in my first year of starting programming. I haven't totally finished the image version and I don't think I ever will. But I might make a very secure encryption application in the future. Don't know yet :)

Can you put the source code up for download? I'm new to BATCH files and I want to learn more. And this looks really good!

Sorry I ain't got my own website yet :/ too busy with university work. Thanks for the comment though :)

[yoyodude55]

Could you maybe send it to my email?

[danielxxv]

I started to change it so it encrypted images too, it works but then there is some error handling i haven't caught. Haven't got around to finishing it lol

[danielxxv]

No problem :)

[forestfeanor]

Thanks. that's definitely handy.

@forestfeanor to generate large primes in java i used the BigInteger class. It has method called nextProbablePrime() ; this method applies primelity tests on the prime returned. It doesnt not 100% generate a prime but its pretty unlikely for it not to be a prime. the probability of it being not a prime (composite) is something like 1 in 126765060022822940149670320537­6. Bare in mind that winning the uk lottery is 1 in about 13,000,000. Hope that helps.

What do you use to generate large primes?
