A preshared secret is most conveniently represented as a sequence of characters, delimited by the double-quote character ". Ask a question. The order of the fields is fixed. The secrets file only contains a reference to these private RSA keys. A raw RSA private key is a composite of eight generally large numbers. Authentication by preshared secret requires that both systems find the identical secret the secret is not actually transmitted by the IKE protocol. Hence in theory, if no one spoofes your IP connection you can simply trust in your connection as authentication and must not use any PSK. The result was the same.
Google didn't find anything about the maximum length except this one post mentioning a max of 32 characters.
