A system and method for communicating a document between multiple locations is disclosed. A computing device receives, via a network, multiple portions of a document signed and/or encrypted at a first location in accordance with a first signing and encryption methodology along with a trailer manifest specifying an order the portions need to be assembled to reconstruct the document. Each of the portions and the manifest is individually decrypted and validated using the first signing and/or encrypting methodology. The portions and manifest are re-signed and/or re-encrypted with a second signing and encryption methodology such that the information can be decrypted, the signatures can be validated and the document can be reassembled at a second location.
