[英]openpgp.js: generate public key text string from private key text string
[英]Calculate the key id of public key using openpgp.js
使用 OpenPGP.js v1.3.0 我可以成功創建一個公鑰/私鑰對並加密/解密確定。
我正在努力使用此函數(在 openpgp.js 和 public_key.js 中找到)獲取密鑰 ID:
/**
* Calculates the key id of the key
* @return {String} A 8 byte key id
*/
PublicKey.prototype.getKeyId = function () {
if (this.keyid) {
return this.keyid;
}
this.keyid = new type_keyid();
if (this.version == 4) {
this.keyid.read(util.hex2bin(this.getFingerprint()).substr(12, 8));
} else if (this.version == 3) {
this.keyid.read(this.mpi[0].write().substr(-8));
}
return this.keyid;
};
PublicKey() 也在 openpgp.js 中:
/**
* @constructor
*/
function PublicKey() {
this.tag = enums.packet.publicKey;
this.version = 4;
/** Key creation date.
* @type {Date} */
this.created = new Date();
/** A list of multiprecision integers
* @type {module:type/mpi} */
this.mpi = [];
/** Public key algorithm
* @type {module:enums.publicKey} */
this.algorithm = 'rsa_sign';
// time in days (V3 only)
this.expirationTimeV3 = 0;
/**
* Fingerprint in lowercase hex
* @type {String}
*/
this.fingerprint = null;
/**
* Keyid
* @type {module:type/keyid}
*/
this.keyid = null;
}
並嘗試像這樣獲取密鑰 ID:
var publickey = openpgp.key.readArmored(myPublicKey);
//var keyID = openpgp.packet.PublicKey(publickey).getKeyId()[0].toHex();
var keyID = openpgp.PublicKey(publickey).getKeyId()[0].toHex();
console.log(keyID);
這給了我錯誤:TypeError: openpgp.PublicKey is not a function。
謝謝。
我在這里問了這個問題: http : //www.mail-archive.com/list@openpgpjs.org/msg00932.html並收到了非常有幫助的答復。
var openpgp = window.openpgp;
var testPublicKey = sessionStorage.getItem('testPublicKey');
var foundKeys = openpgp.key.readArmored(testPublicKey).keys;
if (!foundKeys || foundKeys.length !== 1) {
throw new Error("Key not read, or more than one key found");
}
var pubKey = foundKeys[0]; foundKeys = null;
var getFingerprint = function (key) {
// openpgp.key <- Class
// key <- Instance received by params
return key.primaryKey.fingerprint;
};
var getKeyId = function (key) {
return key.primaryKey.getKeyId().toHex();
}
console.log(getFingerprint(pubKey));
console.log(getKeyId(pubKey));
