/**
 * QCryptoTLSCredsPSK:
 *
 * The QCryptoTLSCredsPSK object provides a representation
 * of the Pre-Shared Key credential used to perform a TLS handshake.
 *
 * This is a user creatable object, which can be instantiated
 * via object_new_propv():
 *
 * <example>
 *   <title>Creating TLS-PSK credential objects in code</title>
 *   <programlisting>
 *   Object *obj;
 *   Error *err = NULL;
 *   obj = object_new_propv(TYPE_QCRYPTO_TLS_CREDS_PSK,
 *                          "tlscreds0",
 *                          &err,
 *                          "dir", "/path/to/dir",
 *                          "endpoint", "client",
 *                          NULL);
 *   </programlisting>
 * </example>
 *
 * Or via QMP:
 *
 * <example>
 *   <title>Creating TLS-PSK credential objects via QMP</title>
 *   <programlisting>
 *    {
 *       "execute": "object-add", "arguments": {
 *          "id": "tlscreds0",
 *          "qom-type": "tls-creds-psk",
 *          "props": {
 *             "dir": "/path/to/dir",
 *             "endpoint": "client"
 *          }
 *       }
 *    }
 *   </programlisting>
 * </example>
 *
 * Or via the CLI:
 *
 * <example>
 *   <title>Creating TLS-PSK credential objects via CLI</title>
 *   <programlisting>
 *  qemu-system-x86_64 --object tls-creds-psk,id=tlscreds0,\
 *          endpoint=client,dir=/path/to/dir[,username=qemu]
 *   </programlisting>
 * </example>
 *
 * The PSK file can be created and managed using psktool.
