RAR for Android is the official app developed by RARLAB, owned by WinRAR.

If you care about the privacy and want to protect the archived file, then a password can be set before opening the archive. The app has default function to support this feature.
Besides compression, it can also easily unpack RAR, ZIP, TAR, GZ, BZ2, XZ, 7z, ISO and ARJ archives to let you view decompressed files on your Android phone or tablet.

It's also capable of repairing broken or damaged achieves due to network error or something else.
