/**
* This parcel stores the input of one or more PgpSignEncrypt operations.
* All operations will use the same general paramters, differing only in
* input and output. Each input/output set depends on the paramters:
* <p/>
* - Each input uri is individually encrypted/signed
* - If a byte array is supplied, it is treated as an input before uris are processed
* - The number of output uris must match the number of input uris, plus one more
* if there is a byte array present.
* - Once the output uris are empty, there must be exactly one input (uri xor bytes)
* left, which will be returned in a byte array as part of the result parcel.
