java RSA Encryption生成带有“\n”字符的字符串，我无法解密

Question

我试图用java创建一个简单的实用程序类，用RSA公钥加密字符串，但我的代码生成了一个带有“\n”字符的加密字符串，无法在服务器上解密

这是我的代码：

private static String ALGORITHM = "RSA";
private static String TRANSFORMATION = "RSA/None/OAEPWithSHA1AndMGF1Padding";

private String encryptData(String txt, SecurityCallback callback) {
        String encoded = "";
        byte[] encrypted = null;
        try {
            String publicKeyContent = getPublicKeyString();
            PublicKey pubKey = stringToPublicKey(publicKeyContent);
            Cipher cipher = Cipher.getInstance(TRANSFORMATION);
            cipher.init(Cipher.ENCRYPT_MODE, pubKey);
            encrypted = cipher.doFinal(txt.getBytes(StandardCharsets.UTF_8));
            encoded = Base64.encodeToString(encrypted, Base64.DEFAULT);
        } catch (Exception exception) {
            callback.onError(exception);
        }
        return encoded;
    }

private String getPublicKeyString() {
        return PUBLIC_KEY.replaceAll("\\n", "").replace("-----BEGIN PUBLIC KEY-----", "").replace("-----END PUBLIC KEY-----", "");
    }

private PublicKey stringToPublicKey(String stringKey) throws InvalidKeySpecException,
            NoSuchAlgorithmException {
        byte[] keyBytes = Base64.decode(stringKey, Base64.DEFAULT);
        X509EncodedKeySpec spec = new X509EncodedKeySpec(keyBytes);
        KeyFactory keyFactory = KeyFactory.getInstance(ALGORITHM);
        return keyFactory.generatePublic(spec);
    }

问题是，在Android中使用该代码生成的加密文本带有一些行尾字符，而后端在尝试转换字符串时出错。所以我通过替换那些末端字符来修复它

不确定为什么在加密过程中添加这些字符
