SSH passphrase keeps saying wrong password

[demyxco]

I decided to make a test key with the command:

ssh-keygen -t RSA

Loaded the privatekey in the form, put the correct password, and then this error keeps popping up:

Wrong password u'test' for decrypting the private key.

I noticed the "u" in the error message, is that character being added on form submission?

Make sure your passphrase is correct.
If you are using Python 2, the error message should be prefixed with the character 'u'.
The form only submits the characters you type.

Why was this closed? I'm still getting the error for passphrase.

The passphrase works because I can connect to the remote server using an actual terminal.

bash-5.0$ ssh demyx@xxx.xxx.xxx.xxx date
Enter passphrase for key '/home/demyx/.ssh/id_rsa':

Is this a python version issue?

[huashengdun]

No, it is not a python version issue.
I have unit tests tested against different Python versions.

As for as I know you can not generate a rsa key with a passphrase of four characters. (minimum five characters)

Same thing with a longer generated password

Wrong password u'1yUsVsjQH4r304' for decrypting the private key.

Any other setting I can check out?

[huashengdun]

I have just tested against a encrypted rsa key and it works as expected.
Did you use a correct passphrase with the right key?
If you use a fake key with a random password, it also prompts you some thing like "Wrong password...".

[demyxco]

What command did you use to generate the RSA? I read somewhere that paramiko doesn’t use openssh library.

[huashengdun]

command like that

ssh-keygen -t rsa -b 2048 -f id_rsa

[demyxco]

Yeah it doesn't work still, I will stick with no password keys for now. Not sure why but I will close as I don't have time to debug it. Great job on the project by the way!

Hi, me again. Seems like the app doesn't like my RSA key generations so I switched to ed25519 and now the passphrase works!

[huashengdun]

[huashengdun]

I use ssh-keygen to generate all the keys:

for t in dsa rsa ecdsa ed25519; do ssh-keygen -t $t -P correctpass -f id_$t; done

From the above image, you see I tested the dsa rsa ecdsa ed25519 keys generated by ssh-keygen and they all work as expected.
So I am curious what tool did you use to generate the keys.

[demyxco]

I've been using this command

ssh-keygen -t rsa

But passphrase doesn't work with your app. So now I'm using:

ssh-keygen -t ed25519

Which is supposedly better than RSA

Hi demyxco,
I have noticed that paramiko doesn't support new key format.
Maybe it is related to your problem.
Here are the links:

Yeah I noticed that macOS doesn't generate the old RSA keys, that's why it didn't work for me. What finally worked was using this:

ssh-keygen -m PEM -t RSA
