GPG加密：我使用正确的密钥吗？

他们给我发了一个公钥文件,我用以下命令检查了密钥(结果如下)：

C:Program Files (x86)GNUGnuPG>gpg2 --dry-run -vvvv --import testthekey.txt

我拿了一个示例文本文件,并使用他们的公钥对其进行加密,然后用这个命令检查了结果文件(结果如下)：

C:Program Files (x86)GNUGnuPG>gpg2 --list-packets <testbankfile.pgp
:compressed packet: algo=1
:pubkey enc packet: version 3,keyid 358DC68F4A83D261
        data: [1019 bits]
        data: [1024 bits]
:encrypted data packet:
        length: 620
gpg: encrypted with ELG key,ID 4A83D261
gpg: decryption failed: No secret key

事情是这样的：当我将文件上传到我们的银行时,他们说文件与他们的私钥不匹配.我看到358DC68F4A83D261的密钥id与他们的公钥相匹配,所以我摸不着头……但我也看到ID为4A83D261的ElGamal密钥似乎没有反映在他们的公钥文件中.

我正在使用基于BouncyCastle库的自定义加密解决方案,因此加密时可能出现错误(我不能使用我自己的Pgp4Win版本复制错误).它们也可能存在问题.我的问题是,我不确定如何阅读这些反馈以确定问题所在.一些建议将不胜感激.
