Type TEncryptBuffer

Previous pageReturn to chapter overviewNext page   

Contains an arbitrary array of bytes.

 

Unit

EEncrypt

 

Syntax

 

Code (Delphi)

TEncryptBuffer = EWinCrypt.DATA_BLOB;

 

Remarks

This is simply a combined Pointer/Size record.

 

pbData field points to the data buffer.

 

cbData field contains the size of data in pbData in bytes.

 

Note

Functions from EEncrypt unit will allocate TEncryptBuffer buffers via AllocMem function. Such allocations can be released via EncryptBufferFree function.

 

Examples

 

Code (Delphi)

var

Buffer: TEncryptBuffer;

begin

// Allocate new buffer (600 bytes)

Buffer.cbData := 600;

Buffer.pbData := AllocMem(EncryptBuffer.cbData);

try

// Work with Buffer

finally

// Release buffer when done

EncryptBufferFree(Buffer); // - same as SecureFree(Buffer);

end;

end;

 

Code (Delphi)

var

Buffer: TEncryptBuffer;

S: RawByteString;

begin

S := 'something';

 

// Point buffer to S

Buffer.cbData := Length(S);

Buffer.pbData := Pointer(S);

 

// Work with Buffer

 

// No need to release Buffer

// (we did not allocate memory for buffer)

end;
