记一次 java 连接 linux ssh服务 权限验证失败的原因和解决过程

下面的问题我是通过之前的ssh测试类找出原因的，因为我的测试类跑通了，但是程序跑不通，看了一下源码发现还有一处没有进行解密，所以才会权限验证失败。

// 出现权限验证失败的原因就在这里，因为老板要求对称加解密，所以上面用 SymmetricEncoder 解码了一下，把数据库中经过 AES 加密的密文解密了，但是下面这行并没有解密，所以权限验证失败

} else {
//                linux
                assetsSingle.setScanrunstatus("5");
                assetsService.update(assetsSingle);
                SSH2Util ssh2Util = new SSH2Util(assetsSingle.getIp(), assetsSingle.getCertificateusername(), SymmetricEncoder.AESDecode("loli", assetsSingle.getCertificatepassword()), Integer.parseInt(assetsSingle.getPort()));
                try {
                    ssh2Util.putFile("C:\RM-ROOT\RM-BASELINE\", "66c221be-6ab2-ef53-1589-fe16877914f4.sh", "/root");
                    ssh2Util.putFile("C:\RM-ROOT\RM-BASELINE\", "66c221be-6ab2-ef53-1589-fe16877914f4.pl", "/root");
// 出现权限验证失败的原因就在这里，因为老板要求对称加解密，所以上面用 SymmetricEncoder 解码了一下，把数据库中经过 AES 加密的密文解密了，但是下面这行并没有解密，所以权限验证失败
                    AssetsSSHScanner.testSSH(assetsSingle, assetsSingle.getIp(), assetsSingle.getCertificateusername(), assetsSingle.getCertificatepassword(), Integer.parseInt(assetsSingle.getPort()), "66c221be-6ab2-ef53-1589-fe16877914f4", "66c221be-6ab2-ef53-1589-fe16877914f4");

                    assetsSingle.setIsscanned("1");
                    assetsSingle.setScanrunstatus("3");
                    assetsSingle.setFailmsg("无错误 : 本次扫描成功");
                    assetsService.update(assetsSingle);
                    List<AssetsWithBLOBs> assetsServiceAll = assetsService.getAll();
                    return ResultUtil.success().add("assetsServiceAll", assetsServiceAll);
                } catch (Exception e) {
                    logger.error(e);
                    assetsSingle.setScanrunstatus("4");
                    AssetsWithBLOBs resultAst = ScanExceptionHandler.fetchResult(e, assetsSingle);
                    assetsService.update(resultAst);
                    List<AssetsWithBLOBs> assetsServiceAll = assetsService.getAll();
                    return ResultUtil.error().add("assetsServiceAll", assetsServiceAll);
                }
            }
