T
Cyd 2b8ca921cb Initial full mirror of c:\VWE (source + assets + toolchain + outputs) via Git LFS 
Complete disaster-recovery snapshot: engine/game source, game data assets,
VC6 toolchain + DX SDKs, build outputs, deployed game, and _UNUSED archive.
Large binaries in Git LFS; text preserved byte-for-byte (core.autocrlf=false,
no eol attributes). See RECOVERY.md for the one-clone rebuild procedure.

//+=========================================================================
// Certificate Store Data Structures and APIs
//==========================================================================
//+-------------------------------------------------------------------------
// In its most basic implementation, a cert store is simply a
// collection of certificates and/or CRLs. This is the case when
// a cert store is opened with all of its certificates and CRLs
// coming from a PKCS #7 encoded cryptographic message.
//
// Nonetheless, all cert stores have the following properties:
// - A public key may have more than one certificate in the store.
// For example, a private/public key used for signing may have a
// certificate issued for VISA and another issued for
// Mastercard. Also, when a certificate is renewed there might
// be more than one certificate with the same subject and
// issuer.
// - However, each certificate in the store is uniquely
// identified by its Issuer and SerialNumber.
// - There's an issuer of subject certificate relationship. A
// certificate's issuer is found by doing a match of
// pSubjectCert->Issuer with pIssuerCert->Subject.
// The relationship is verified by using
// the issuer's public key to verify the subject certificate's
// signature. Note, there might be X.509 v3 extensions
// to assist in finding the issuer certificate.
// - Since issuer certificates might be renewed, a subject
// certificate might have more than one issuer certificate.
// - There's an issuer of CRL relationship. An
// issuer's CRL is found by doing a match of
// pIssuerCert->Subject with pCrl->Issuer.
// The relationship is verified by using
// the issuer's public key to verify the CRL's
// signature. Note, there might be X.509 v3 extensions
// to assist in finding the CRL.
// - Since some issuers might support the X.509 v3 delta CRL
// extensions, an issuer might have more than one CRL.
// - The store shouldn't have any redundant certificates or
// CRLs. There shouldn't be two certificates with the same
// Issuer and SerialNumber. There shouldn't be two CRLs with
// the same Issuer, ThisUpdate and NextUpdate.
// - The store has NO policy or trust information. No
// certificates are tagged as being "root". Its up to
// the application to maintain a list of CertIds (Issuer +
// SerialNumber) for certificates it trusts.
// - The store might contain bad certificates and/or CRLs.
// The issuer's signature of a subject certificate or CRL may
// not verify. Certificates or CRLs may not satisfy their
// time validity requirements. Certificates may be
// revoked.
//
// In addition to the certificates and CRLs, properties can be
// stored. There are two predefined property IDs for a user
// certificate: CERT_KEY_PROV_HANDLE_PROP_ID and
// CERT_KEY_PROV_INFO_PROP_ID. The CERT_KEY_PROV_HANDLE_PROP_ID
// is a HCRYPTPROV handle to the private key assoicated
// with the certificate. The CERT_KEY_PROV_INFO_PROP_ID contains
// information to be used to call
// CryptAcquireContext and CryptProvSetParam to get a handle
// to the private key associated with the certificate.
//
// There exists two more predefined property IDs for certificates
// and CRLs, CERT_SHA1_HASH_PROP_ID and CERT_MD5_HASH_PROP_ID.
// If these properties don't already exist, then, a hash of the
// content is computed. (CERT_HASH_PROP_ID maps to the default
// hash algorithm, currently, CERT_SHA1_HASH_PROP_ID).
//
// There are additional APIs for creating certificate and CRL
// contexts not in a store (CertCreateCertificateContext and
// CertCreateCRLContext).

// Open the cert store using the specified store provider.

// hCryptProv specifies the crypto provider to use to create the hash

// The store doesn't need to use a private
// key. If the CERT_STORE_NO_CRYPT_RELEASE_FLAG isn't set, hCryptProv is
// CryptReleaseContext'ed on the final CertCloseStore.
//
// Note, if the open fails, hCryptProv is released if it would have been
// released when the store was closed.
//
// If hCryptProv is zero, then, the default provider and container for the
// PROV_RSA_FULL provider type is CryptAcquireContext'ed with
// CRYPT_VERIFYCONTEXT access. The CryptAcquireContext is deferred until
// the first create hash or verify signature. In addition, once acquired,
// the default provider isn't released until process exit when crypt32.dll
// is unloaded. The acquired default provider is shared across all stores
// and threads.
//
// After initializing the store's data structures and optionally acquiring a
// default crypt provider, CertOpenStore calls CryptGetOIDFunctionAddress to
// get the address of the CRYPT_OID_OPEN_STORE_PROV_FUNC specified by
// lpszStoreProvider. Since a store can contain certificates with different
// encoding types, CryptGetOIDFunctionAddress is called with dwEncodingType
// set to 0 and not the dwEncodingType passed to CertOpenStore.
// PFN_CERT_DLL_OPEN_STORE_FUNC specifies the signature of the provider's
// open function. This provider open function is called to load the
// store's certificates and CRLs. Optionally, the provider may return an
// array of functions called before a certificate or CRL is added or deleted
// or has a property that is set.
//
// Use of the dwEncodingType parameter is provider dependent. The type
// definition for pvPara also depends on the provider.
//
// Store providers are installed or registered via
// CryptInstallOIDFunctionAddress or CryptRegisterOIDFunction, where,
// dwEncodingType is 0 and pszFuncName is CRYPT_OID_OPEN_STORE_PROV_FUNC.
//
// Here's a list of the predefined provider types (implemented in crypt32.dll):
//
// CERT_STORE_PROV_MSG:
// Gets the certificates and CRLs from the specified cryptographic message.
// dwEncodingType contains the message and certificate encoding types.
// The message's handle is passed in pvPara. Given,
// HCRYPTMSG hCryptMsg; pvPara = (const void *) hCryptMsg;
//
// CERT_STORE_PROV_MEMORY
// sz_CERT_STORE_PROV_MEMORY:
// Opens a store without any initial certificates or CRLs. pvPara
// isn't used.
//
// CERT_STORE_PROV_FILE:
// Reads the certificates and CRLs from the specified file. The file's
// handle is passed in pvPara. Given,
// HANDLE hFile; pvPara = (const void *) hFile;
//
// For a successful open, the file pointer is advanced past
// the certificates and CRLs and their properties read from the file.
// Note, only expects a serialized store and not a file containing
// either a PKCS #7 signed message or a single encoded certificate.
//
// The hFile isn't closed.
//
// CERT_STORE_PROV_REG:
// Reads the certificates and CRLs from the registry. The registry's
// key handle is passed in pvPara. Given,
// HKEY hKey; pvPara = (const void *) hKey;
//
// The input hKey isn't closed by the provider. Before returning, the
