# QCryptoTLSCredsEndpoint:
#
# The type of network endpoint that will be using the credentials.
# Most types of credential require different setup / structures
# depending on whether they will be used in a server versus a
# client.
#
# @client: the network endpoint is acting as the client
#
# @server: the network endpoint is acting as the server
#
# Since: 2.5

#
# The data format that the secret is provided in
#
# @raw: raw bytes. When encoded in JSON only valid UTF-8 sequences can be used
# @base64: arbitrary base64 encoded binary data
# Since: 2.6
