$fh.sec(options, callback)

キーの生成、データの暗号化および暗号解除。

7.1. 例

RSA キー生成

$fh.sec({
  "act": 'keygen',
  "params": {
    "algorithm": "RSA", // RSA or AES
    "keysize": 1024 // 1024 or 2048 for RSA
  }
}, function (err, res) {
  if (err) {
    return console.log("RSA key generation failed. Error: " + err);
  }
  return console.log("Public key is " + res.public + " Private key is " + res.private + ' Modulu is ' + res.modulu);
});

RSA 暗号化

$fh.sec({
  "act": 'encrypt',
  "params": {
    "algorithm": "RSA", // padding: PKCS#1
    "plaintext": "Need more starting pages",
    "public": pubkey
  }
}, function (err, result) {
  if (err) {
    return console.log("Encryption failed: " + err);
  }
  return console.log("Encrypted data is " + result.ciphertext);
});

RSA 暗号解除

$fh.sec({
  "act": 'decrypt',
  "params": {
    "algorithm": "RSA",
    "ciphertext": "23941A28432482E374102FF48723BCB9847324",
    "private": privatekey
  }
}, function (err, result) {
  if (err) {
    return console.log("Decryption failed: " + err);
  }
  return console.log("Decryption data is " + result.plaintext);
});

AES キー生成

$fh.sec({
  "act": 'keygen',
  "params": {
    "algorithm": "AES", // AES or RSA
    "keysize": 128 // 128 or 256 for AES
  }
}, function (err, res) {
  if (err) {
    return console.log("AES key generation failed. Error: " + err);
  }
  return console.log("AES secret key is " + res.secretkey + " Initialisation Vector is " + res.iv);
});

AES 暗号化

$fh.sec({
  "act": 'encrypt',
  "params": {
    "algorithm": "AES", // mode : CBC, padding: PKCS#5
    "plaintext": "Need more starting pages",
    "key": secretkey,
    "iv": iv
  }
}, function (err, result) {
  if (err) {
    return console.log("Encryption failed: " + err);
  }
  return console.log("Encrypted data is " + result.ciphertext);
});

AES 暗号解除

$fh.sec({
  "act": 'decrypt',
  "params": {
    "algorithm": "AES",
    "ciphertext": "23941A28432482E374102FF48723BCB9847324",
    "key": secretkey,
    "iv": iv
  }
}, function (err, result) {
  if (err) {
    return console.log("Decryption failed: " + err);
  }
  return console.log("Decryption data is " + result.plaintext);
});
