Electronic data can be conveyed. A processor of a first intermediate device can receive a first file. The processor can decrypt the first file to produce a second file. The second file can include a third file and an identification. The identification can be for a destination device. The third file can include the electronic data. The third file can be encrypted with respect to the first intermediate device. The processor can determine, based on the identification, a second intermediate device. The second intermediate device can be different from the destination device. The processor can produce a fourth file. The fourth file can include the third file and the identification. The processor can encrypt the fourth file to produce a fifth file. The processor can convey, to the second intermediate device, the fifth file.
