<p>Things i tried:</p>
<ul>
<li>included |- , &gt;-, only |,only &gt;</li>
<li>tried enclosing in double quotes with backslash as escape character</li>
</ul>
<p>something like below</p>
<pre><code>         &quot;PuTTY-User-Key-File-2: ssh-rsa\
         Encryption: none\
         Comment: rsa-key-20210504...&quot;
still got the same error as above

<p>i tried with type as kubernetes.io/ssh-auth instead of Opaque
and it worked !!
