// 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 CryptSetProvParam 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

//
// CERT_STORE_MANIFOLD_FLAG can be set to check for certificates having the

//
// By default, contexts having the CERT_ARCHIVED_PROP_ID, are skipped

// CERT_STORE_READONLY_FLAG can be set to open the store as read only.

//
// CERT_STORE_OPEN_EXISTING_FLAG can be set to only open an existing

//
// hCryptProv specifies the crypto provider to use to create the hash
// properties or verify the signature of a subject certificate or CRL.
// 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
// provider opens it own copy of the hKey.
//
// If CERT_STORE_READONLY_FLAG is set, then, the registry subkeys are
// RegOpenKey'ed with KEY_READ_ACCESS. Otherwise, the registry subkeys
// are RegCreateKey'ed with KEY_ALL_ACCESS.
//
// This provider returns the array of functions for reading, writing,
// deleting and property setting certificates and CRLs.
// Any changes to the opened store are immediately pushed through to
// the registry. However, if CERT_STORE_READONLY_FLAG is set, then,
// writing, deleting or property setting results in a
// SetLastError(E_ACCESSDENIED).
//
// Note, all the certificates and CRLs are read from the registry
// when the store is opened. The opened store serves as a write through
// cache.
//
// If CERT_REGISTRY_STORE_SERIALIZED_FLAG is set, then, the
// contexts are persisted as a single serialized store subkey in the
// registry.
//
// CERT_STORE_PROV_PKCS7:
// sz_CERT_STORE_PROV_PKCS7:
// Gets the certificates and CRLs from the encoded PKCS #7 signed message.
// dwEncodingType specifies the message and certificate encoding types.
// The pointer to the encoded message's blob is passed in pvPara. Given,
// CRYPT_DATA_BLOB EncodedMsg; pvPara = (const void *) &EncodedMsg;
//
// Note, also supports the IE3.0 special version of a
// PKCS #7 signed message referred to as a "SPC" formatted message.
//
// CERT_STORE_PROV_SERIALIZED:
// sz_CERT_STORE_PROV_SERIALIZED:
// Gets the certificates and CRLs from memory containing a serialized
// store. The pointer to the serialized memory blob is passed in pvPara.
// Given,
// CRYPT_DATA_BLOB Serialized; pvPara = (const void *) &Serialized;
//
// CERT_STORE_PROV_FILENAME_A:
// CERT_STORE_PROV_FILENAME_W:
// CERT_STORE_PROV_FILENAME:
// sz_CERT_STORE_PROV_FILENAME_W:
// sz_CERT_STORE_PROV_FILENAME:
// Opens the file and first attempts to read as a serialized store. Then,
// as a PKCS #7 signed message. Finally, as a single encoded certificate.
// The filename is passed in pvPara. The filename is UNICODE for the
// "_W" provider and ASCII for the "_A" provider. For "_W": given,
// LPCWSTR pwszFilename; pvPara = (const void *) pwszFilename;
// For "_A": given,
// LPCSTR pszFilename; pvPara = (const void *) pszFilename;
//
// Note, the default (without "_A" or "_W") is unicode.
//
// Note, also supports the reading of the IE3.0 special version of a
// PKCS #7 signed message file referred to as a "SPC" formatted file.
//
// CERT_STORE_PROV_SYSTEM_A:
// CERT_STORE_PROV_SYSTEM_W:
// CERT_STORE_PROV_SYSTEM:
// sz_CERT_STORE_PROV_SYSTEM_W:
// sz_CERT_STORE_PROV_SYSTEM:
// Opens the specified logical "System" store. The upper word of the
// dwFlags parameter is used to specify the location of the system store.
//
// A "System" store is a collection consisting of one or more "Physical"
// stores. A "Physical" store is registered via the
// CertRegisterPhysicalStore API. Each of the registered physical stores
// is CertStoreOpen'ed and added to the collection via
// CertAddStoreToCollection.
//
// The CERT_SYSTEM_STORE_CURRENT_USER, CERT_SYSTEM_STORE_LOCAL_MACHINE,
// CERT_SYSTEM_STORE_CURRENT_SERVICE, CERT_SYSTEM_STORE_SERVICES,
// CERT_SYSTEM_STORE_USERS, CERT_SYSTEM_STORE_CURRENT_USER_GROUP_POLICY,
// CERT_SYSTEM_STORE_LOCAL_MACHINE_GROUP_POLICY and
// CERT_SYSTEM_STORE_LOCAL_MACHINE_ENTERPRSE
// system stores by default have a "SystemRegistry" store that is
// opened and added to the collection.
//
// The system store name is passed in pvPara. The name is UNICODE for the
// "_W" provider and ASCII for the "_A" provider. For "_W": given,
// LPCWSTR pwszSystemName; pvPara = (const void *) pwszSystemName;
// For "_A": given,
// LPCSTR pszSystemName; pvPara = (const void *) pszSystemName;
//
// Note, the default (without "_A" or "_W") is UNICODE.
//
// The system store name can't contain any backslashes.
//
// If CERT_SYSTEM_STORE_RELOCATE_FLAG is set in dwFlags, pvPara
// points to a CERT_SYSTEM_STORE_RELOCATE_PARA data structure instead
// of pointing to a null terminated UNICODE or ASCII string.
// Sibling physical stores are also opened as relocated using
// pvPara's hKeyBase.
//
// The CERT_SYSTEM_STORE_SERVICES or CERT_SYSTEM_STORE_USERS system

//
// Stores on remote computers can be accessed for the

// Iterates through all the certificates in the chain checking for either
// a szOID_BASIC_CONSTRAINTS or a szOID_BASIC_CONSTRAINTS2 extension. If
// neither extension is present, the certificate is assumed to have
// valid policy. Otherwise, for the first certificate element, checks if
// it matches the expected CA_FLAG or END_ENTITY_FLAG specified in
// pPolicyPara->dwFlags. If neither or both flags are set, then, the first
// element can be either a CA or END_ENTITY. All other elements must be
// a CA. If the PathLenConstraint is present in the extension, its
// checked.
//
// The first elements in the remaining simple chains (ie, the certificate
// used to sign the CTL) are checked to be an END_ENTITY.
//
// If this verification fails, dwError will be set to
// TRUST_E_BASIC_CONSTRAINTS.

// CERT_CHAIN_POLICY_NT_AUTH
//
// Implements the NT Authentication chain policy.
//
// The NT Authentication chain policy consists of 3 distinct chain
// verifications in the following order:
// [1] CERT_CHAIN_POLICY_BASE - Implements the base chain policy
// verification checks. The LOWORD of dwFlags can be set in
// pPolicyPara to alter the default policy checking behaviour. See
// CERT_CHAIN_POLICY_BASE for more details.
//
// [2] CERT_CHAIN_POLICY_BASIC_CONSTRAINTS - Implements the basic
// constraints chain policy. The HIWORD of dwFlags can be set
// to specify if the first element must be either a CA or END_ENTITY.
// See CERT_CHAIN_POLICY_BASIC_CONSTRAINTS for more details.
//
// [3] Checks if the second element in the chain, the CA that issued
// the end certificate, is a trusted CA for NT
// Authentication. A CA is considered to be trusted if it exists in
// the "NTAuth" system registry store found in the
// CERT_SYSTEM_STORE_LOCAL_MACHINE_ENTERPRISE store location.
// If this verification fails, whereby the CA isn't trusted,
// dwError is set to CERT_E_UNTRUSTEDCA.
