Namespace:

Gets a value that indicates whether Encrypt(Byte[]) and Decrypt(Byte[]) can accept buffers that are different block sizes in length.

public:
 property bool CanMergeBlocks { bool get(); };
public bool CanMergeBlocks { get; }
member this.CanMergeBlocks : bool
Public ReadOnly Property CanMergeBlocks As Boolean

Property Value

Boolean

true if the buffer passed to Encrypt(Byte[]) can be a different length from the buffer passed to Decrypt(Byte[]); otherwise, false if the buffers passed to Encrypt(Byte[]) and Decrypt(Byte[]) must be the exact same length. For AES the default is true.

Remarks

The clearText and cipherText buffers passed to Encrypt and Decrypt must be n*BlockSize bytes in length, where 'n' is an integer greater than or equal to 1.

If CanMergeBlocks is false, buffers passed to Encrypt must be the same length as the buffers passed to Decrypt.

If CanMergeBlocks is true, buffers passed to Encrypt can be a different length from the buffers passed to Decrypt (all buffer sizes must still always be a multiple of BlockSize bytes in length).
