I just released Tarsnap version 1.0.41. This contains mitigations for a chosen-plaintext attack against Tarsnap's chunking algorithm which can leak its secret parameters.

Paper: Should be on the Cryptology ePrint archive soon; I'll post when it's up.

Because we want to protect the most vulnerable members of our community, @BSDCan is requiring face masks this year.

Because I know people will forget, @Tarsnap is exercising its Silver sponsorship to include "vendor swag" in the tote bags: Two KN95 masks per person.

Just updated the @tarsnap .deb packages to use the 2024 signing keys instead of the 2023 signing keys (which expire on 2024-02-01). If your apt-get is now breaking, you forgot to install (or update) the tarsnap-archive-keyring package.

[Colin Percival @cperciva]

Tarsnap is back online.

[Colin Percival @cperciva]

Tarsnap is offline due to a hardware failure. I'm working on bringing it back. All your data is safe, just temporarily inaccessible.

Donated $1000 to support Glen Barber's work on FreeBSD. He's an excellent release engineer and works incredibly hard to keep the project running smoothly.

I hope other companies using FreeBSD will also contribute.

[FreeBSD Foundation @freebsdfndation]

Our annual Ottawa developer summit would not be possible without the generous support of sponsors; the #FreeBSD Foundation would like to thank @Tarsnap for their gold-level sponsorship. https://t.co/N07H3dsJVH

[Colin Percival @cperciva]

If any Tarsnap users are affected by the SVB meltdown, just send me an email and I'll be happy to make sure your data is safe despite liquidity issues. I just need to know that there's a problem and you still want to keep your data.

[Colin Percival @cperciva]

Since I've been asked: @Tarsnap has no direct exposure to Silicon Valley Bank, and as far as I'm aware has no indirect exposure either. It's business as usual here.

[AsiaBSDCon @asiabsdcon]

@Tarsnap has joined as a silver sponsor. Thanks a lot, @cperciva!

[Colin Percival @cperciva]

Sign up for Michael Lucas' mailing lists and get a free (digital) copy of his Tarsnap Mastery book. Seriously, do it. It's a great book.

[Colin Percival @cperciva]

For the record, @tarsnap is not presently hiring. If you recently received an email from "me" saying that I want to hire you: Sorry, it wasn't from me.
