• RESOLUTION SUMMARY:
  
  A code fix is provided.
  
  As part of addressing this issue, we have created two new BPML
  parameters for the Crypto Message Service.
  
  1. pipeSize -     Size of the pipe (in bytes) created for
  carrying out the pipeline activities.
                           Defaults to a value of 4096.
                           Optional.
                           Allowed values - any valid non-negative
  integer values
                           NOTE :-
                                         1. The pipeSize value
  should always be greater than the bufferSize value.
                                         2. This parameter shall
  be used only when dealing with large MIME headers where the
  header size is > 1024 bytes.
  
  
  2. bufferSize -     Size of the buffer(in bytes) to hold the
  incoming data.
                             Defaults to a value of 1024.
                             Optional.
                             Allowed values - any valid
  non-negative integer values
                             NOTE :-
                                           1. The pipeSize value
