Hi

I have a problem with the base interface for the EC algorithm's private and public key implementations
I want to verify my sign array with OpenSSL library (c++) , but I have a problem:

I am using in JavaCard (java): ALG_ECDSA_SHA and for generate keys LENGTH_EC_F2M_163 , ALG_EC_F2M
result for this:

Kód: Vybrať všetko

private key: 21B,
public key 43B
signDataLenght 48B r,s sequnce
hash diggest is 20B.

and the lenghts are incorrect for OpenSSL, because I have aplication which use library OpenSSL and I am using algorithm:
NID_sect163k1 for Elliptic Curve.

Kód: Vybrať všetko

#define SN_sect163k1        "sect163k1"
#define NID_sect163k1        721
#define OBJ_sect163k1        OBJ_secg_ellipticCurve,1L

result for OpenSSL for generate keys is:

Kód: Vybrať všetko

private key: 202B
public key: 43B
sign: 42B r,s sequnce
hash diggest: 20B

sign exam:

question is: How can I approve my verify and signature in javacard, what i will have to use? Can I use OpenSSL lib ? If yes which algorithm I will have to use in OpenSSL when I use (ALG_EC_F2M, ALG_ECDSA_SHA) in java card ....
Thanks.....
