Seahorse opens all ssl certs fine unless it has a password

I started using seahorse to inspect my SSL certs and keys when I opened one from nemo by mistake. I find seahorse quite useful. The other day however I ran into a problem where Seahorse prompts me for the password to my key but then tells me the password is incorrect.

I created the key using:

openssl req -new -out cert.csr -keyout privkeyFT.pem -newkey rsa:2048 -passout pass:password

and I am able to provide the password, verify and display the key using:

openssl rsa -in privkeyMINT.pem -text -inform PEM -noout

When providing the password to Seahorse I am told “The password was incorrect”

Linux Mint 22.1
Mint System has OpenSSL 3.0.13 30 Jan 2024 (Library: OpenSSL 3.0.13 30 Jan 2024) and Seahorse version 43.0

Is this a bug or not intended use?
