Name	Initial	Comment
Untrusted	1	This is the location for untrusted certificates.
Trusted		This is the location for trusted CA or self signed certificates.
Own		This is the location for certificates used by the PLC. The private key of these certificates is available.
Quarantine		This location contains certificates which could not be verified because of missing chains.
Unknown		This is the default for certificates which are not in one of the other stores. Usually this is set when parsing a certificate.
Chain		This location contains chain certificates. These certificates are not trusted but used to build up a chain up to one of the certificates placed in trusted. This is the only store which is local to each opened certificate store. Also adding certificates to this trust level is not persistent. The typical use case is to add chain-certificates received from the communication peer in case of an own protocol implementation. For TLS connection this is done automatically. Due this use-case, the capabilities of this store are somewhat limited. It is not possible to iterate or filter certificates on this store. Explicit removal of certificates is supported with X509CertStoreRemoveCert. The store is automatically clean up on X509CertStoreClose.
