我正在使用GEMALTO USB密钥智能卡，我想在我的PDF文件中添加数字签名。
为此，我在Google上阅读了几篇有关此主题的文章。经过这些阅读之后，我成功编写了一个Javascript代码，可以从我的令牌中获取PRIVATE_KEY，PUBLIC_KEY和SIGNATURE，如下所示：
var pkcs11js = require("pkcs11js");
var fs = require('fs');
var forge = require('node-forge');
var pkcs11 = new pkcs11js.PKCS11();
pkcs11.load("C:/Program Files/Gemalto/Classic Client/BIN/gclib.dll");
pkcs11.C_Initialize();
try {
// Getting info about PKCS11 Module
var module_info = pkcs11.C_GetInfo();
console.log("1- INFO MODULE: ",module_info);
// Getting list of slots
var slots = pkcs11.C_GetSlotList(true);
console.log("2- SLOTS: ",slots);
var slot = slots[0];
console.log("3- SLOT: ",slot);
// Getting info about slot
var slot_info = pkcs11.C_GetSlotInfo(slot);
console.log("4- INFO SLOT: ",slot_info);
// Getting info about token
var token_info = pkcs11.C_GetTokenInfo(slot);
console.log("5- INFO TOKEN: ",token_info);
// Getting info about Mechanism
var mechs = pkcs11.C_GetMechanismList(slot);
console.log("6- MECHANISM: ",mechs);
var mech_info = pkcs11.C_GetMechanismInfo(slot, mechs[0]);
console.log("7- INFO MECHANISM: ",mech_info);
var session = pkcs11.C_OpenSession(slot, pkcs11js.CKF_RW_SESSION | pkcs11js.CKF_SERIAL_SESSION);
console.log("8- SESSION: ",session);
// Getting info about Session
var info = pkcs11.C_GetSessionInfo(session);
pkcs11.C_Login(session, 1, "856489");
console.log("9- INFO SESSION: ",info);
/** MY CODE **/
//-- GET Private Key --*/
var keys = {privateKey: null, publicKey: null};
pkcs11.C_FindObjectsInit(session, [
{ type: pkcs11js.CKA_CLASS, value: pkcs11js.CKO_PRIVATE_KEY },
{ type: pkcs11js.CKA_LABEL, value: "My RSA Private Key" }
]);
var hObject = pkcs11.C_FindObjects(session);
console.log("10-1/ hObject Private BEFORE WHILE: ",hObject)
while (hObject) {
var attrs = pkcs11.C_GetAttributeValue(session, hObject, [
{ type: pkcs11js.CKA_CLASS },
{ type: pkcs11js.CKA_TOKEN },
{ type: pkcs11js.CKA_LABEL }
]);
keys.privateKey = hObject;
hObject = pkcs11.C_FindObjects(session);
}
console.log("10-2/ hObject Private AFTER WHILE: ",hObject);
console.log("Private KEY: ",keys.privateKey);
pkcs11.C_FindObjectsFinal(session);
//-- GET Public Key --*/
pkcs11.C_FindObjectsInit(session, [
{ type: pkcs11js.CKA_CLASS, value: pkcs11js.CKO_PUBLIC_KEY },
{ type: pkcs11js.CKA_LABEL, value: "My RSA Public Key" }
]);
var hObject = pkcs11.C_FindObjects(session);
console.log("11-1/ hObject Public BEFORE WHILE: ",hObject)
while (hObject) {
var attrs = pkcs11.C_GetAttributeValue(session, hObject, [
{ type: pkcs11js.CKA_CLASS },
{ type: pkcs11js.CKA_TOKEN },
{ type: pkcs11js.CKA_LABEL }
]);
keys.publicKey = hObject;
hObject = pkcs11.C_FindObjects(session);
}
console.log("11-1/ hObject Public AFTER WHILE: ",hObject);
console.log("Public KEY: ",keys.publicKey);
pkcs11.C_FindObjectsFinal(session);
let pdf = fs.readFileSync("C:/APEX/Projets/PDF_SignElec/Files/McGhan_AngularJS.pdf");
const lastChar = pdf.slice(pdf.length - 1).toString();
if (lastChar === '\n') {
// remove the trailing new line
pdf = pdf.slice(0, pdf.length - 1);
}
console.log("12- PDF File: ",pdf);
//console.log("13- PDF File: ",pdf.toString('binary'));
//-- Signature --
pkcs11.C_SignInit(session, { mechanism: pkcs11js.CKM_SHA256_RSA_PKCS }, keys.privateKey);
pkcs11.C_SignUpdate(session, pdf);
var signature = pkcs11.C_SignFinal(session, Buffer(256));
console.log("14- Signature: ",signature.toString("hex"));
//Vérification
pkcs11.C_VerifyInit(session, { mechanism: pkcs11js.CKM_SHA256_RSA_PKCS }, keys.publicKey);
pkcs11.C_VerifyUpdate(session, pdf);
var verify = pkcs11.C_VerifyFinal(session, signature);
console.log("15- Vérification: ",verify);
/* END CODE */
}
catch(e){
console.error(e);
}
finally {
pkcs11.C_Finalize();
}
我得到这个结果：

现在我的问题是：如何从javascript令牌中获取X.509证书，并将其放在pdf文件中？
谢谢您的帮助。
