Descrição
Métodos
|
class function GetBlockSize: integer; override; |
|
procedure Reset; override; |
|
Get the block size of the cipher (in bits) | |
|
procedure Burn; override; |
|
Reset any stored chaining information | |
|
procedure SetIV(const Value); override; |
|
Clear all stored key information and chaining information | |
|
procedure GetIV(var Value); override; |
|
Sets the IV to Value and performs a reset | |
|
procedure Init(const Key; Size: longword; InitVector: pointer); override; |
|
Returns the current chaining information, not the actual IV | |
|
procedure EncryptCFB8bit(const Indata; var Outdata; Size: longword); override; |
|
Do key setup based on the data in Key, size is in bits | |
|
procedure DecryptCFB8bit(const Indata; var Outdata; Size: longword); override; |
|
Encrypt size bytes of data using the CFB (8 bit) method of encryption | |
