]HashAlgorithm class
Base class for hashing algorithms. Objects of this class should only be allocated using System::MakeObject() function. Never create instance of this type on stack or using operator new, as it will result in runtime errors and/or assertion faults. Always wrap this class into System::SmartPtr pointer and use this pointer to pass it to functions as argument.
class HashAlgorithm : public System::Security::Cryptography::ICryptoTransform
Methods
| Method | Description |
|---|---|
| ComputeHash(const ArrayPtr<uint8_t>&) | Hashes buffer. |
| ComputeHash(const ArrayPtr<uint8_t>&, int, int) | Hashes buffer slice. |
| ComputeHash(SharedPtr<IO::Stream> const&) | Reads stream until end and calculates hash for the data read. |
| static Create(const String&) | Creates hash algorithm based on name. |
| virtual get_Hash() | Gets value of calculated hash code. |
| virtual get_HashSize() | Gets size of calculated hash value in bytes. |
| get_InputBlockSize() override | Input block size. |
| get_OutputBlockSize() override | Output block size. |
| virtual Initialize() | Resets hasher into initial state. |
| TransformBlock(ArrayPtr<uint8_t>, int, int, ArrayPtr<uint8_t>, int) override | Processes block of data and copies data to output array. |
| TransformFinalBlock(ArrayPtr<uint8_t>, int, int) override | Processes last block of data and calculates hash. |
| virtual ~HashAlgorithm() | Destructor. |
