That's a great idea and makes things even safer. I don't know much about PKCS5 but would SHA512 also be safe enough for hashing the password?

SHA512 would then generate a 128 characters hash which I would then pass to the parameter "-o plugin/mail_crypt_private_password=" of my "doveadm mailbox cryptokey generate ..." command.
