The "tar file encoding" saves the file + metadata (filename and modification) in a "tar" format that is required in the RDE spec, even though it only contains a single file. This is only relevant for RyDE, and not for Ghostryde. In fact, the only reason Ghostryde exists is to not have the TAR layer. Currently we only encrypt RyDE, so we only need the TAR encoding. We plan to add decryption ability so we can test files we sent to IronMountain if there's a problem - so we will need TAR decoding for that. The new file - RydeTar.java - has both encoding and decoding. We keep the format used for all other Input/OutputStreams for consistency, even though in this case it could be a private part of the RyDE encoder / decoder. This is one of a series of CLs - each merging a single "part" of the encoding. ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=208056757
