/**
* 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.
