我可以在客戶端使用jsbn成功生成公鑰/私鑰對。使用這些密鑰加密和解密客戶端很好。我也可以將該公鑰傳輸到服務器,並通過PHP將其存儲在MySQL中。phpseclib/jsbn:用PHP中的公鑰加密,用jsbn中的私鑰解密
我無法使用jsbn公鑰對PHP中的某些內容進行加密,然後使用jsbn私鑰對客戶端進行解密。
// attempting to encrypt in PHP using the jsbn public key.
// (this public key came from jsbn client side)
$jsbn_public_key = '763989d1f75a779dae752ac236b011e85f9496bb414d72f5e89bf44274a942277fab2d4f5c58a57634d4000eecc8009d2efaeff17aa4a0efae2c4d41f3423be88be043628c6bac86f97deaadf23231793e6fa02550fb2ca65b2600e074205d23338e28ab3c5e92265e6bd7995c173085e3dc042e59ef464c5ed058c3ad863911';
$rsa = new Crypt_RSA();
$rsa->setPublicKeyFormat(CRYPT_RSA_PUBLIC_FORMAT_PKCS1); // tried various options here.
$public_key = array(
'n' => new Math_BigInteger($jsbn_public_key, 16),
'e' => new Math_BigInteger('65537', 10), // same value as jsbn
);
$rsa->loadKey($public_key,CRYPT_RSA_PUBLIC_FORMAT_RAW); // tried various options here.
$ciphertext = $rsa->encrypt($value);
$ciphertext_web_safe = bin2hex($ciphertext); // I think this is where the problem is!
// $ciphertext_web_safe looks something like this:
// 1b02bee0422028accba74f37e6e6974125fd16bdf83a72b8d6462e140ee6e85adae869fddc5e83635aaf90bc6074a3128890eeadf9537c33ebdfd665e16a3f1b617fa2fa5454f469e84f86d77ffcbc234dfc8a32291fbc84df61a0098c97fd90bb10204f68e783d9996678cd7853f3cbd932a4a067cb7f4f9eb62ca0542964f6
// which is exactly the same length as an encrypted string generated by jsbn
而這裏的客戶端加密:
var my_rsa = {
....
e: "65537",
public_key: '763989d1f75a779dae752ac236b011e85f9496bb414d72f5e89bf44274a942277fab2d4f5c58a57634d4000eecc8009d2efaeff17aa4a0efae2c4d41f3423be88be043628c6bac86f97deaadf23231793e6fa02550fb2ca65b2600e074205d23338e28ab3c5e92265e6bd7995c173085e3dc042e59ef464c5ed058c3ad863911',
encrypt: function(value){
var rsakey = new RSAKey();
rsakey.setPublic(this.public_key, this.e);
return rsakey.encrypt(value);
},
decrypt: function(ciphertext){
var rsakey = new RSAKey();
rsakey.setPrivateEx(this.public_key, this.e, this.private_key.d, this.private_key.p, this.private_key.q, this.private_key.dmp1, this.private_key.dmq1, this.private_key.coeff);
return rsakey.decrypt(ciphertext);
},
....
};
當我嘗試解密JavaScript中的'$ ciphertext_web_safe的價值,我只是得到一個空字符串。控制檯日誌等沒有錯誤。
在PHP中使用「bin2hex」有問題嗎?在將加密的二進制數據轉換爲十六進制之前,是否應該有某種填充等等?
