cryptofs 0.6.0

March 05, 2012 — BarryK
I posted yesterday about creating a portable Sylpheed. But, the issue was raised that the email login passwords are stored in plain text.

Well, so are all the emails. I was thinking, what if someone stole my laptop? This got me thinking that I could implement an encrypted filesystem inside the Sylpheed installation.

Toward that end, I have compiled Cryptofs, which can encrypt an entire directory.

Here is the PET (230KB):

The only dependency is libfuse, which is in all puppies. Cryptofs does require libgpg-error and libgcrypt, however I linked those statically into the 'cryptofs' executable.

"Nice pet thanks, works well in wary but not in pup420extreme. (turbopup_xtreme_v1-dillo.iso) Got error: "cryptofs: symbol lookup error: cryptofs: undefined symbol: g_malloc0_n " So it does at the moment not work in all puppies.

"This message is a good resource from MU, including my last post 6: I have not used Sylpheed for a few years, having found Thunderbird 2 a bit friendlier. The other impression is that searching and backing up all the individual MH files with SyncBack is slower than the single mbox files. Am I wrong? I have huge mailboxes. But I wouldn't mind looking at Sylpheed again for its compactness.I no longer use GPG. Nor news.

Will SM be entended to use this

"@B arry, will you/someone publish using this Crypto appraoch for SM/Thnunderbird? This has general applicability to any PC based email we use in Puppyland. Here to help

"You have to take it as a general rule that anything compiled in Wary is likely to work in all the 5.0+ puppies. For the 4.0+ puppies, sometimes it works, sometimes not. In this case not, so you would have to compile it especially.
