Problem with Passphrase option in Script

Hi,
I have created a script using Private Key Files. Also using the -passphrase option. But my Passphrase isn't working. I suggest it is a problem with special characters.

Passphrase: My,P%=!#"a$=k"-5,2"23'"phase
This is an example with same special characters as the original.

Is there any way I could automate my script without changing the Passphrase (not possible for me).

Script:
If I use the Script without -passphrase option and enter the Passphrase manually when asked for, it works.

Most likely that you chose you use double quotes inside a double quoted string.

100% of the times it's better to not have password that contains certain characters, like single or double quotes or ending in an escape character.

Use a password with no quotes or escape them. See how that goes.

In fact, that was my initial assumption...

I can't change the password on my own, it is really complex to do so. If it was this easy, I would do that already.

Tried also Encoding like in Password field, but it seems this is not possible in Passphrase field.

If this is a keyfile pass phrase and then use Pageant?

Hi,
I read about Pageant already, but as this is a customer environment, it is not so easy to install a new software.
So I would prefer a solution without additional software if possible. Maybe there is any way I could pass my Passphrase trough the -passphrase option.

You have to double the double quotes:

Though in general, I do not see what is complicated about re-saving your private key with more sensible passphrase. Just load your key to PuTTYgen, change the passphrase and save it back.

Many Many THANKS!!! It works now!
Searched hours trough the FAQ and Forum, but did not notice this hint.

I'm not allowed to change Keys. It is a customer managed enviroment with limited access for me.
