 number or address was being written to the ledger, then you likely would not want
 this data to appear in plaintext.  Chaincode encryption is achieved by leveraging

 which is a BCCSP wrapper with commodity factories and functions to perform cryptographic
 operations such as encryption and elliptic curve digital signatures.  For example,
 to encrypt, the invoker of a chaincode passes in a cryptographic key via the
 transient field.  The same key may then be used for subsequent query operations, allowing
 for proper decryption of the encrypted state values.

 helper program.  This utility loads the chaincode shim APIs and Entities extension
 and builds a new class of functions (e.g. ``encryptAndPutState`` & ``getStateAndDecrypt``)
