NAME

       OSSL_STORE-winstore - OpenSSL built in OSSL_STORE for Windows

DESCRIPTION

       The OSSL_STORE implementation for Windows provides access to Windows' system "ROOT"
       certificate store through URIs, using the URI scheme "org.openssl.winstore".

   Supported URIs
       There is only one supported URI:

         org.openssl.winstore:

       No authority (host, etc), no path, no query, no fragment.

   Supported OSSL_STORE_SEARCH operations
       OSSL_STORE_SEARCH_by_name(3)
           As a matter of fact, this must be used.  It is not possible to enumerate all available
           certificates in the store.

   Windows certificate store features
       Apart from diverse constraints present in the certificates themselves, the Windows
       certificate store also has the ability to associate additional constraining properties
       alongside a certificate in the store. This includes both documented and undocumented
       capabilities:

       •   The documented capability to override EKU

       •   The undocumented capability to add name constraints

       •   The undocumented capability to override the certificate expiry date

       Such constraints are not checked by this OSSL_STORE implementation, and thereby not
       honoured.

       However, once extracted with OSSL_STORE_load(3), certificates that have constraints in
       their X.509 extensions will go through the usual constraint checks when used by OpenSSL,
       and are thereby honoured.

HISTORY

       The winstore ("org.openssl.winstore") implementation was added in OpenSSL 3.2.0.

NOTES

       OpenSSL uses OSSL_DECODER(3) implementations under the hood.  To influence what
       OSSL_DECODER(3) implementations are used, it's advisable to use OSSL_STORE_open_ex(3) and
       set the propq argument.
