[Pepper](https://github.com/jovibor/Pepper) is one of the apps that is built on top of the **libpe**.

## [](#)Usage
```cpp
import libpe;

int main() {
    libpe::Clibpe pe(L"C:\\myFile.exe"); //or pe.OpenFile(L"C:\\myFile.exe");
    const auto peImp = pe.GetImport();
    if(peImp) {
    ...
    }
    ...
}
```

## [](#)Methods
### OpenFile
```cpp
auto OpenFile(const wchar_t* pwszFile)->int;
```
Opens a file for further processing, until [`CloseFile`](#closefile) is called or `Clibpe` object goes out of scope and file closes automatically in destructor.
```cpp
libpe::Clibpe pe;
if(pe.OpenFile(L"C:\\MyFile.exe") == PEOK) {
    ...
}
```

### [](#)CloseFile();
```cpp
void CloseFile();
```
Explicitly closes file that was previously opened with the [`OpenFile(const wchar_t*)`](#openfile). This method is invoked automatically in `Clibpe` destructor.

### [](#)GetDOSHeader
```cpp
[[nodiscard]] auto GetDOSHeader()const->std::optional<IMAGE_DOS_HEADER>;

Returns a file's standard **MSDOS** header.

### [](#)GetRichHeader
```cpp
[[nodiscard]] auto GetRichHeader()const->std::optional<PERICHHDR_VEC>;
```
Returns an array of the unofficial and undocumented so called **«Rich»** structures.
```cpp
struct PERICHHDR {
    DWORD dwOffset; //File's raw offset of the entry.
    WORD  wId;      //Entry Id.
    WORD  wVersion; //Entry version.
    DWORD dwCount;  //Amount of occurrences.
};
using PERICHHDR_VEC = std::vector<PERICHHDR>;
```

### [](#)GetNTHeader
```cpp
[[nodiscard]] auto GetNTHeader()const->std::optional<PENTHDR>;
```
Returns a file's **NT** header.
```cpp
struct PENTHDR {
    DWORD dwOffset;   //File's raw offset of the header.
    union UNPENTHDR { //Union of either x86 or x64 NT header.
        IMAGE_NT_HEADERS32 stNTHdr32; //x86 Header.
        IMAGE_NT_HEADERS64 stNTHdr64; //x64 Header.
    } unHdr;
};
```

### [](#)GetDataDirs
```cpp

##### Example:
The next code snippet populates `std::wstring` with all resources' types and names that PE binary possesses, and prints it to the standard `std::wcout`.
```cpp
#include <format>
#include <iostream>
#include <string>

import libpe;
using namespace libpe;

int main()
{
    libpe::Clibpe pe;
    if (pe.OpenFile(L"C:\\Windows\\notepad.exe") != PEOK) {

### [](#)GetCOMDescriptor
```cpp
[[nodiscard]] auto GetCOMDescriptor()const->std::optional<PECOMDESCRIPTOR>;

    IMAGE_COR20_HEADER stCorHdr; //Standard IMAGE_COR20_HEADER struct.
};
```

## [](#)Helper Methods
These freestanding methods do not need an active `Clibpe` object with an opened file. They instead take references to the previously obtained structures.

### [](#)GetFileType
```cpp
[[nodiscard]] inline constexpr auto GetFileType(const PENTHDR& stNTHdr)->EFileType
```
Returns **PE** file type in form of the `EFileType` enum.
```cpp
enum class EFileType : std::uint8_t {
    UNKNOWN = 0, PE32, PE64, PEROM
};
```

### [](#)GetImageBase
```cpp
[[nodiscard]] inline constexpr auto GetImageBase(const PENTHDR& stNTHdr)->ULONGLONG
```
Returns file's **Image Base**.

### [](#)GetOffsetFromRVA
```cpp
[[nodiscard]] inline constexpr auto GetOffsetFromRVA(ULONGLONG ullRVA, const PESECHDR_VEC& vecSecHdr)->DWORD
```
Converts file's RVA to the file's physical raw offset on disk.

### [](#)FlatResources
```cpp
[[nodiscard]] inline constexpr auto FlatResources(const PERESROOT& stResRoot)
```
This function is kind of a light version of the `GetResources` method. It takes `PERESROOT` struct returned by the `GetResources`, and returns `std::vector` of `PERESFLAT` structures.  
`PERESFLAT` is a light struct that only possesses pointers to an actual resources data, unlike heavy `PERESROOT`. `FlatResources` flattens all resources, making accessing them more convenient.
```cpp
struct PERESFLAT {
    std::span<const std::byte> spnData { };    //Resource data.
    std::wstring_view          wsvTypeStr { }; //Resource Type name.
    std::wstring_view          wsvNameStr { }; //Resource Name name (resource itself name).
    std::wstring_view          wsvLangStr { }; //Resource Lang name.
    WORD                       wTypeID { };    //Resource Type ID (RT_CURSOR, RT_BITMAP, etc...).
    WORD                       wNameID { };    //Resource Name ID (resource itself ID).
    WORD                       wLangID { };    //Resource Lang ID.
};
using PERESFLAT_VEC = std::vector<PERESFLAT>;
```

## [](#)Maps
A **PE** file consists of many structures, they in turn possess many fields some of which have predefined values.  
These maps are meant to alleviate such fields' conversion to a human-reading format. They are simple `std::unordered_map<DWORD, std::wstring_view>` maps.

Note that some fields can only have one value, while the others can combine many values with a bitwise `or |` operation.

### [](#)MapFileHdrMachine
This map forms one of the values from `IMAGE_NT_HEADERS::IMAGE_FILE_HEADER::Machine` field.

### [](#)MapFileHdrCharact
This map forms one or more values from `IMAGE_NT_HEADERS::IMAGE_FILE_HEADER::Characteristics` field.
```cpp
const auto pNTHdr = m_pLibpe->GetNTHeader();
const auto pDescr = &pNTHdr->unHdr.stNTHdr32.FileHeader; //Same for both x86/x64.
std::wstring  wstrCharact;
for (const auto& flags : MapFileHdrCharact) {
    if (flags.first & pDescr->Characteristics) {
        wstrCharact += flags.second;
        wstrCharact += L"\n";
    }
}
```

### [](#)MapOptHdrMagic
This map forms one of the values from `IMAGE_NT_HEADERS::IMAGE_OPTIONAL_HEADER::Magic` field.

### [](#)MapOptHdrSubsystem
This map forms one of the values from `IMAGE_NT_HEADERS::IMAGE_OPTIONAL_HEADER::Subsystem` field.

### [](#)MapOptHdrDllCharact
This map forms one or more values from `IMAGE_NT_HEADERS::IMAGE_OPTIONAL_HEADER::DllCharacteristics` field.
```cpp
const auto pNTHdr = m_pLibpe->GetNTHeader();
const auto pOptHdr = &pNTHdr->unHdr.stNTHdr32.OptionalHeader //For x64: pNTHdr->unHdr.stNTHdr64.OptionalHeader
std::wstring wstrCharact;
for (const auto& flags : MapOptHdrDllCharact) {
    if (flags.first & pOptHdr->DllCharacteristics) {
        wstrCharact += flags.second;
        wstrCharact += L"\n";
    }
}
```

### [](#)MapSecHdrCharact
This map forms one or more values from `IMAGE_SECTION_HEADER::Characteristics` field.
```cpp
const auto pSecHeaders = m_pLibpe->GetSecHeaders();
std::wstring wstrCharact;
auto IdOfSection = 0; //ID of desired section.
for (const auto& flags : MapSecHdrCharact) {
    if (flags.first & pSecHeaders->at(IdOfSection).stSecHdr.Characteristics) {
        wstrCharact += flags.second;
        wstrCharact += L"\n";
    }
}
```

### [](#)MapResID
This map forms one of the values from `IMAGE_RESOURCE_DIRECTORY_ENTRY::Id` field.

### [](#)MapWinCertRevision
This map forms one of the values from  `WIN_CERTIFICATE::wRevision` field.

### [](#)MapWinCertType
This map forms one of the values from `WIN_CERTIFICATE::wCertificateType` field.

### [](#)MapRelocType
This map forms one of the values from `PERELOCDATA::wRelocType` field.

### [](#)MapDbgType
This map forms one of the values from `IMAGE_DEBUG_DIRECTORY::Type` field.

### [](#)MapTLSCharact
This map forms one of the values from `IMAGE_TLS_DIRECTORY::Characteristics` field.

### [](#)MapLCDGuardFlags
This map forms one or more values from `IMAGE_LOAD_CONFIG_DIRECTORY::GuardFlags` field.
```cpp
const auto pLCD = m_pLibpe->GetLoadConfig();
const auto pPELCD = &pLCD->unLCD.stLCD32; //For x64: pLCD->unLCD.stLCD64
std::wstring wstrGFlags;
for (const auto& flags : MapLCDGuardFlags) {
    if (flags.first & pPELCD->GuardFlags) {
        wstrGFlags += flags.second;
        wstrGFlags += L"\n";
    }
}
```

### [](#)MapCOR20Flags
This map forms one or more values from `IMAGE_COR20_HEADER::Flags` field.
```cpp
const auto pCOMDesc = m_pLibpe->GetCOMDescriptor();
std::wstring wstrFlags;
for (const auto& flags : MapCOR20Flags) {
    if (flags.first & pCOMDesc->stCorHdr.Flags) {
        wstrFlags += flags.second;
        wstrFlags += L"\n";
    }
}
```
