使用openpgp.js计算公钥的密钥ID

使用OpenPGP.js v1.3.0我可以成功创建公钥/私钥对并加密/解密。

我正在努力使用此函数获取密钥ID(在openpgp.js和public_key.js中找到):

 <div class="form-group">
          <%= f.label :street_number %>
          <%= f.number_field :street_number, class: "form-control", required: true %>
    </div>

PublicKey()也在openpgp.js中:

/**
 * 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;
};

并尝试获取这样的密钥ID:

/**
 * @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;
}

这给了我错误: TypeError:openpgp.PublicKey不是函数。

感谢。

问这里的问题: this answer 并收到了非常有帮助的回复。

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 readed, or more than one key");
}

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));
