It seems like Paramiko has problems with RSA files. Either that, or there's something I don't understand. Here is what I did. First I generated the key pair:
$ ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/home/me/.ssh/id_rsa): /tmp/test
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /tmp/test.
Your public key has been saved in /tmp/test.pub.
The key fingerprint is:
SHA256:Xfz89Pi/p+YccZzfUULJiyssLJ/lRs/voTETLyOT25Q me@localhost.localdomain
The key's randomart image is:
+---[RSA 2048]----+
| ... |
| . .o |
| o....|
| . ..o.oo|
| .S.. ..+o+|
| . o =..+ *=|
| o *++E = =|
| o o*oO.+.|
| .. o=*o*|
+----[SHA256]-----+
And then I tried to import that file:
$ python3
Python 3.7.0 (default, Aug 30 2018, 14:32:33)
[GCC 8.2.1 20180801 (Red Hat 8.2.1-2)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import paramiko
>>> p = paramiko.RSAKey.from_private_key_file('/tmp/test')
Traceback (most recent call last):

raise SSHException("not a valid " + tag + " private key file")
paramiko.ssh_exception.SSHException: not a valid RSA private key file
I cannot see what I could have possibly done wrong. The paramiko version is 2.4.2
I read about a hack here where they edited the keyfile by changing "OPENSSH" to "RSA" but that did not work either.
