Can the link be updated to not be to the end of the page?

Yes, that would be nice - when I posted it I forgot to clean the URL. I'm sorry! I've sent an email to moderators to request the change.

Update: URL has been updated

It’s just not the same thing. There is significant overlap, but it’s not enough to be a reasonable suggestion. You can’t suggest a service as a replacement for a local offline tool. It’s like saying “Why do you need VLC when you can just run peertube?”. Also since then, age is the real replacement for pgp in terms of sending encrypted files. Wormhole is a different use case.

Sticking to the use case of serving that 0.1% of users, why can’t a service or other encrypted transport be a solution? Why doesn’t Signal fit the bill for instance?

i like the approach by the bsd people. shut the f* up and code.

as long as there's not (audited and verified) replacements for each niche, we still have to use it.

sadly even gpg (because of all this fud'ing around) even falls now the grace and tries to say "well, not THAT application, only THAT".. sigh.

I’m still frustrated by the criticism because I internalized it a couple of years ago and tried to move to age+minisig because those are the only 2 scenarios I personally care about. The overall experience was annoying given that the problems with pgp/gpg are esoteric and abstract that unless I’m personally are worried about a targeted attack against me, they are fine-ish. If someone scotch tapes age+minisig and conv…

Has Tarsnap become inadequate, security-wise? The service may be expensive for a standard backup. It had a serious bug in 2011, but hasn't it been adequate since then?

you cannot selfhost it. it's not verified and audited independently as a whole system.

for some people, that's important

Have a sentence praising Signal followed by a sentence explaining the main critique of Signal (requiring mobile number) makes me question the whole post for credibility

Recently, this opinionated list of PGP alternatives went around:

https://soatok.blog/2024/11/15/what-to-use-instead-of-pgp/

One use case I've not seen covered is sending blobs asynchronously with forward secrecy. Wormhole requires synchronously communicating the password somehow, and Signal requires reasonable buy-in by the recipient.

Basically, I'd like to just email sensitive banking and customer data in an encrypted attachment without needing to trust that the recipient will never accidentally leak their encryption key.

Adding to my comment since it was downvoted:

There are two parts of "sending encrypted files": the encryption and the sending. An offline tool (e.g. PGP or age) seems only necessary when you want to decouple the two. After all, you can't do the sending with an offline tool (except insofar as you can queue up a message while offline, such as with traditional mail clients).

The question thereby becomes "Why decouple the sending from encryption?"

As far as I can see, the main (only?) reason is if the communication channel used for sending doesn't align with your threat model. For instance, maybe there are multiple parties at the other end of the channel, but you only trust one of them. Then you'd need to do something like encrypt the message with that person's key.

But in the use-case you mentioned (not wanting to publicly post a log file), I don't see why that reason would hold; surely the people who would send you logs can trust trust Signal every bit as easily as PGP. Share your Signal username over your existing channel (the mailing list), thereby allowing these people to effectively "upgrade" their channel with you.
