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
