javascript - RSA 使用 jsencrypt 加密并使用 bouncy caSTLe 解密？

Question

对了，我有个小问题。我正在使用 Javascript 库 (jsencrypt) 在浏览器中加密消息。然后将此消息发送到后端，在后端使用 Java 库 (bouncycaSTLe) 对其进行解密。我的问题是虽然我可以使用这两个库来加密和解密消息，但它们似乎不想一起工作。因此，当我在浏览器中加密我的消息并将其发送到后端时，我最终得到了乱码。有人知道这里发生了什么吗？

var text = "This is another msg!";

var encrypt = new JSEncrypt();
encrypt.setPublicKey(pubkey);
var ciphertext = encrypt.encrypt(text);
console.log("ciphertext  : " + ciphertext);

var decrypt = new JSEncrypt();
decrypt.setPrivateKey($("#privkey").val());
var plaintext = decrypt.decrypt(ciphertext);
console.log("plaintext  : " + plaintext);

@EbbeM.Pedersen

You are properly getting different default padding modes. Keywords like RSA-OAEP padding & PKCS#1 padding comes to mind.

确实是这个问题。我将 bouncycaSTLe 中的默认填充更改为 PKCS#1，现在一切正常。

感谢一百万。
