RSA implementation

[rozick1]

I'm trying to implement the RSA algorithm. I've generated keys successfully and tested them here : http://www.strangeattractor.ca/RSAdemo.html against what the ciphertext should be. The strange thing is that even with large numbers loads of ciphertext is the same despite having completely different keys.

Is this normal?

Thanks!

No. Nor is it correct.

Why don't you test it against a known RSA implementation like openssl?
