Wallet - do the Master Encryption Key limitations affect a set SFTP-connection or any of it's keys?

Summary:

Dear CCC-community,

maybe someone can answer if those two limitations at the "Master Encryptions Key"-section as part of Manage System Security Options will affect the usage of a created SFTP-connection or it's related Client Key or PGP Encryption Key or the Signature Key as part of Manage Transmission Configuration?

We set a new SFTP-connection in Oracle Cloud's Manage Transmission Configuration. When we select at the Client Private Key the option "Quick Create" from the list of values we got an error: "You must enter either a valid wallet file or wallet file path. (IBY-825218)"
