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.
Release announcement: mail.tarsnap.com/tarsnap-announ… Blog post: daemonology.net/blog/2025-03-2… Paper: Should be on the Cryptology ePrint archive soon; I'll post when it's up.
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.
Tarsnap's Black Friday sale is live! For an unlimited time, you can get three tools which I wrote for Tarsnap's internal use -- kivaloo, scrypt, and spiped -- for the low price of $0.00! tarsnap.com/open-source.ht…

Just released scrypt-1.3.2: mail.tarsnap.com/scrypt/msg0027…
Added some details about outages to the @Tarsnap website: tarsnap.com/infrastructure… To save you a click: 99.93% uptime since 2008; slightly higher over the past 5 years.
Tarsnap outage post-mortem: mail.tarsnap.com/tarsnap-announ…
Tarsnap is back online. mail.tarsnap.com/tarsnap-announ…
Tarsnap is offline due to a hardware failure. I'm working on bringing it back. All your data is safe, just temporarily inaccessible. mail.tarsnap.com/tarsnap-announ…
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. gofundme.com/f/gjbbsd
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. wiki.freebsd.org/DevSummit/2023…
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.
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.
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.
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.
Tarsnap now has experimental amd64 binary packages for Ubuntu 22.04 "jammy". Ubuntu made some compatibility-breaking changes in 22.04 so it took a while for us to get these ready (usually supporting a new Linux is very quick). mail.tarsnap.com/tarsnap-users/…
Does any product in the world have a better collection of testimonials than Tarsnap? Imagine getting a testimonial from Robert Morris. It's hard to get even a yes/no answer out of him. tarsnap.com/testimonials.h…
