Hello All,
As per EMV standard we require two RSA keys.
1) Issuer RSA Keys ( will use 1408 bit)
2) ICC RSA Keys ( will use 1152 bit)
Here Issuer RSA private keys are use to calculate ICC public key certificate. A EMV card contain various Tag like 8F , 90 (issuer public key certificate) 9F46 (ICC PUBLIC KEY CERTIFICATE) etc that use in SDA/DDA.
Actually I want to calculate these all values ( using Java) and want to perform SDA/DDA operation by my own for better understanding.
Here I need clear RSA keys which I will use during tag calculation as well as in SDA/DDA operation.
Also EMV have DGI8201-8205 that contian ICC RSA private key in CRT format.
Could any body tell me how can I get RSA keys that can solve my purpose and can use it in EMV calculation. thanks in Advance.
