method ConnectionOptions.pskCallback
#ConnectionOptions.pskCallback(hint: string | null): PSKCallbackNegotation | nullWhen negotiating TLS-PSK (pre-shared keys), this function is called
with optional identity hint provided by the server or null
in case of TLS 1.3 where hint was removed.
It will be necessary to provide a custom tls.checkServerIdentity()
for the connection as the default one will try to check hostname/IP
of the server against the certificate but that's not applicable for PSK
because there won't be a certificate present.
More information can be found in the RFC 4279.
Parameters #
#hint: string | null message sent from the server to help client
decide which identity to use during negotiation.
Always null if TLS 1.3 is used.
Return Type #
PSKCallbackNegotation | null Return null to stop the negotiation process. psk must be
compatible with the selected cipher's digest.
identity must use UTF-8 encoding.
