mega.co.nz module for Plowshare

This module is more a proof of concept of making cryptography with Bash rather than a reliable plugin.

Features:

• Anonymous download
• Anonymous & account upload
  • Support shares
  • Upload chuck by chunk successively not simultaneously
• Folder link listing

Restrictions:

• Account password must not exceed 16 characters

Usage

Download

Anonymous download:

$ plowdown 'https://mega.co.nz/#!EqkzGDoT!E9mAzHvHTsKmORXrzBlstUdGDWxQCMghpng-GoRhRRK'

Note: Don't forget to simple quote links because ! is reserved by Bash for history substitution.

Ignore CRCs

Concerning file encryption (AES-128-CTR), mega does not check cipher itself but only verify correct meta-MAC (64-bit hash) and well formed data (using AES 128-bit key + 2*32-bit IV). Technically, any symmetric cipher could be used, even plaintext!

Use --ignore-crc switch to ignore meta-MAC mismatch: allow to get the file even if meta-MAC verification fails.

Upload

Account upload (public file):

$ plowup mega -a 'email:password' <file>

Note: : is the separator character for login and password.

# In a (local or remote) folder. Specify leaf name only, no path.
$ plowup mega -a 'email:password' --folder=MyBackup <file>

Note: Anonymous upload (i.e. ephemeral session) has been disabled by mega in early 2014.

Account upload (private file):

$ plowup mega -a 'email:password' --private <file>

Optional options:

• --nossl: use HTTP upload url instead of HTTPS
• --eu: use eu.api.mega.co.nz servers instead of g.api.mega.co.nz
• --multi=N: uses curl's --next switch to process several chunks at once (requires curl 7.36+)

Upload process is slow and inefficient because file is cut into chunks which are uploaded successively. It's not advised to use with big files.

List

Anonymous public folder:

$ plowlist 'https://mega.co.nz/#F!94wGHLbd!nx8UQbcMZTuFGMhJvFk_ZQ'
