Currently I can upload certificates with keys including special characters to the "Certificates" tab under "Certificates". Unfortunately, uploading the same certificate under the "Certificate authorities" tab results in the following error:

Special characters |, `, ', ", <, >, (, ) and \ are not allowed in the passphrase

I don't see why special characters can be used in the passphrase for "Certificates" but not "Certificate authorities". Please allow special characters to be used in passphrases under "Certificate authorities".
