CryptoProvider.CanMergeBlocks Property

Gets a value that indicates whether Encrypt and Decrypt can accept buffers that are different block sizes in length.

Namespace:  System.Security.RightsManagement
Assembly:  WindowsBase (in WindowsBase.dll)

public bool CanMergeBlocks { get; }

Property Value

Type: System.Boolean
true if the buffer passed to Encrypt can be a different length from the buffer passed to Decrypt; otherwise, false if the buffers passed to Encrypt and Decrypt must be the exact same length. For Advanced Encryption Standard (AES) the default is true.

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).
