Le sigh. There must be a simpler way, but I cannot find it. Trying to get the SHA256 fingerprint of a x509 certificate as one long string without colons or something works with:

`openssl x509 -in roots.pem -noout -fingerprint -sha256 | sed 's/://g' | sed 's/^.*=//' | awk '{print tolower($0)}'`

UPDATE: This is what I now have in my .bashrc 😀

function certfp(){ openssl x509 -in "$1" -outform DER | sha256sum | cut -d' ' -f1 ; }

openssl x509 -in roots.pem -outform DER | openssl dgst -sha256 | cut -d' ' -f2

That's the simplest, I can come up with. No sed, no awk. Just openssl and a single cut

@Larvitz Because I am weird:

openssl x509 -in roots.pem -outform DER | sha256sum | cut -d' ' -f1

openssl x509 -in roots.pem -outform DER | sha256sum | tr -d "*-"

;)

@Larvitz If you just sha256sum it will always add a ' -' to indicate that the input was STDIN. There is no option in sha256sum to avoid that. Le sigh. @donburi

How about this? That would mitigate it (too):

openssl x509 -in cert.pem -outform DER | sha256sum | head -c64

I'll keep the version with cut in my cheatsheet. I find it more explicit and common, that just relying on the number of characters.

But that's now just a question of personal taste/preference 😀

If not adverse to other libraries, `gnutls-certtool --fingerprint --infile X` generates exactly by default the output you want (defaults to SHA256 hashing but `--hash` option allows to select other). Manual also gives out clearly what you came to at the end: "This is a simple hash of the DER encoding of the certificate.". And maybe relevant for your use case: "However, it is recommended for identification to use the key-id which depends only on the certificate's key.". YMMV

How do you all feel about Justin Trudeau dating Katy Perry?

Is he actually dating her? Or are they just friends sharing a meal? JT is pretty good at keeping his private life private.

New blog post time!

The finale of Core Design July is Banshee, a shoot 'em up that combines elements of games like 1942 and Twinbee into something that works way better than you might expect. Add in detailed visuals and a bit of humor and you've got a great showpiece for the Amiga and Core Design alike:

For a second I was thinking I had more music in the gamerip from this, but I think I'm thinking of Blastar... I wonder what happened here? Just ran out of space/resources to play in-game music?
in reply to Misty

@misty Blastar is more likely to be what you're thinking of since that one has a full OST compared to Banshee, but yeah, it's very strange how little music there is in this!

I picked the CD32 version thinking they would have added some beyond the intro and ending, but nope! I'd like to know why as well, I couldn't find anything about it and previous Core Design games didn't skimp on music, so it could very well have been some kind of time/budget/space constraint unique to its development




⏪ 10 years ago, #mifepristone was approved for use in Canada, significantly changing the landscape of abortion access.

Attacks on mifepristone in the U.S. fuel dangerous misinformation + stigma around medication abortion.

With the facts, we can dispel myths + equip folks to make informed decisions about their bodies! 🧑‍🏫

It's really funny how the official way to run SDL 1.2 programs on SDL 3.0 is by using the SDL 1.2→SDL 2 compatibility layer, and can then using that with the SDL 2→SDL 3 compatibility layer
