]SymmetricAlgorithm class
Symmetric algorithm using same key for encryption and decryption base class. 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 SymmetricAlgorithm : public virtual System::Object
Methods
| Method | Description |
|---|---|
| static Create(const String&) | Creates algorithm instance. |
| virtual CreateDecryptor() | Creates decryptor with parameters associated with algorithm object. |
| virtual CreateDecryptor(System::ArrayPtr<uint8_t>, System::ArrayPtr<uint8_t>) | Creates decryptor with explicit parameters. |
| virtual CreateEncryptor() | Creates encryptor with parameters associated with algorithm object. |
| virtual CreateEncryptor(System::ArrayPtr<uint8_t>, System::ArrayPtr<uint8_t>) | Creates encryptor with explicit parameters. |
| virtual GenerateIV() | Generates random initial value for the algorithm. Overrides existing one (if any). |
| virtual GenerateKey() | Generates random key for the algorithm. Overrides existing one (if any). |
| virtual get_BlockSize() | Gets block size of cryptographic operation. |
| virtual get_FeedbackSize() | Gets feedback size of cryptographic operation. |
| virtual get_IV() | Gets initial value of cryptographic operation. Creates new if not created yet. |
| virtual get_Key() | Gets key of cryptographic operation. Creates new if not created yet. |
| virtual get_KeySize() | Gets key size of cryptographic operation. |
| virtual get_Mode() | Gets mode of cryptographic operation. |
| virtual get_Padding() | Gets padding of cryptographic operation. |
| virtual set_BlockSize(int) | Sets block size of cryptographic operation. |
| virtual set_FeedbackSize(int) | Sets feedback size of cryptographic operation. |
| virtual set_IV(System::ArrayPtr<uint8_t>) | Sets initial value of cryptographic operation. |
| virtual set_Key(System::ArrayPtr<uint8_t>) | Sets key of cryptographic operation. |
| virtual set_KeySize(int) | Sets key size of cryptographic operation. |
| virtual set_Mode(CipherMode) | Sets mode of cryptographic operation. |
| virtual set_Padding(PaddingMode) | Sets padding of cryptographic operation. |
| ValidKeySize(int) | Checks if key size is valid. |
