我使用PuTTYgen创建了一个公钥和私钥,并将公钥复制到我的用户帐户下的.ssh / authorized_keys.

然后我尝试在尝试登录时指定私钥,但显然它不会提取它并继续询问我原来拥有的用户名/密码.我正在使用WinSCP连接并在高级/身份验证部分指定私钥.我错过了WinSCP中的任何步骤吗？

authorized_keys的内容如下所示

ssh-rsa AAAAB3NzaC1yc2EAAAABpEVSiiRXi7tOHpkOyFa9w2OLpBep31k9lePCK7RQxsdfs9u11+rdu0XCidRKOY5j4anD1eDaNBj87wqZbsreRe5cFcsakyGUAYXAvqgGApvsep31k9lePCK7RQxlOY5j4anD1eDaNBj8LJO++K3SkUN8E0srRBO8YyMT6Y03/F7+AAAAB3NzaC1yc2Q4h2RLGtr12CDKSBVAnFEc+JucuF4uF0WY4Sh66MSFI63mCQFu9iYNYwWyT6lUo6sks4WypEVSiiRXi7tOHpkOyFa9w2OLpBzAlTA/VSQwdNTFYUI1vquaufZ9ORzTa6dkbBRo/mLVdevYSRMSDw1BUcinYz/ogdxRvw==

我将.ssh的权限更改为700,将authorized_keys的权限更改为600.

虽然我进入WinSCP中的身份验证部分并指定私钥(如屏幕截图所示),但它看起来仍然需要用户名和密码,并且不会提取它.

当我使用PuTTY并指定私钥时,输入登录用户名后就会显示

Server refused our key

这是PuTTY的日志
