如何从Java中的epass2003读取证书

Question

我想在插入eToken时从eToken中读取证书，当我将其存储在计算机上时可以读取我的证书，但是我想从epass2003中读取证书。我不知道如何从epass2003中读取它。所以，请帮我 感谢advnce

String fileName = "C:\\myCert.cer";

InputStream inStream = new FileInputStream(fileName);
CertificateFactory cf = CertificateFactory.getInstance("X.509");
X509Certificate cert = (X509Certificate)cf.generateCertificate(inStream);
inStream.close();
