Hi Jean-Pierre,
Yes, in encrypted communication you must use the buffer size of the encryption method. This means this is the smallest buffer size and if you need larger buffers, it must be a multiple of the minimum buffer size.
Some crypto libraries fill the buffer for you under the hood. If you use 2K3DES or 3K3DES cipher you have to use 8 byte buffers and for AES128 16 bytes buffer size.
