you should give us more details about your question.

In JavaCardAPI, the JCSystem.getAvailableMemory() API may help you get your want.

I forgot the CRT RSA...

Have you down the work about DES and 3DES? What is the different between DES and 3DES?

DaHuFa

I think you should find the answer form GP specification.

It is not a trouble to standard RSA private key.
For example, C is ciphertext, D is the private key, N is modulo, M is plaintext.
So, M = (C^D) mod N
So easy.

yeah, I will try it.

en, thank you very much~

Thanks for your answer! Now, I have a new problem. For the 192 bits test, the parameters are: P = {0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFE, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF}; A = {0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xF...

ECC algorithm has five parameters: A, B, P, N, and G. I want to know the range of N.
According to the range of private key(private key must be in [1, n-1]), n must be bigger than 1. So, Is I right?
