TPM2 command encoding with #bincode and #serde:

            let options = DefaultOptions::new()
                .with_fixint_encoding()
                .with_big_endian();
            buf.extend(&options.serialize(&(Tag::NoSessions as u16)).unwrap());
            buf.extend(&options.serialize(&22_u32).unwrap());
            buf.extend(
                &options
                    .serialize(&(CommandCode::GetCapability as u32))
                    .unwrap(),
            );
            buf.extend(&options.serialize(&(Capability::Handles as u32)).unwrap());
            buf.extend(&options.serialize(&HR_PERSISTENT).unwrap());
            buf.extend(&options.serialize(&1_u32).unwrap());

Just noticed that #aerc has native support for #zoxide: see :z. #email

Would make porting all sorts of old protocol stacks to #Rust so much easier if the enum fields could have aliased names. #rustlang

I'm looking into repealing and replacing the error type with this with the error type from my lab project: https://github.com/tpm-rs/tpm-rs/issues/71

Language Server Protocol really would need a competitor with a #plugin based architecture.

Then editor and analyzer could have:

1. A better memory and caching strategy.
2. Both faster performance and lower operation latency.

#LSP is IMHO is exactly like the worst ideas of lrzsz modified to work as a language analyzer.

#telescope is awesome with the #kernel tree #neovim

The work on #bootc Is coming along very nice! This morning keynote by @cgwalters, Dan Walsh, and Stef Walter was very nice to see the current state of it in #Fedora and CentOS Stream. #devconf_cz

#neovim in #fedora 40 does this when opening a #lua file:

When cargo publish -p tpm2_cli , I need to

tpm2_call = "0.1.1"

… while building locally:

tpm2_call = { path = "../tpm2_call" }

How to sort this out in “idiomatic manner”?

#rust #rustlang

A crate for #TPM 2.0 library protocol, or beginnings of it: https://gitlab.com/jarkkojs/tpm2_library/

Sub-crates:

1. tpm2_call for TPM 2.0 library protocol shenanigans.
2. tpm2_cli for a command-line interfaces.

Development process:

• https://www.conventionalcommits.org/en/v1.0.0/
• https://semver.org/
• Signed-off-by’s.

I aim to do cli first as Linux tied but it could also have e.g. Windows backend. tpm2_call will be portable between operating systems.

#TPM2 #Rust #rustlang

Not really a real project. I've been ad-hoc scripting with #python since 2005, and wanted to learn how to "devops" a properly pipeline at #gitlab, with a release ending to the #pypi: https://pypi.org/project/eth0/

PS. I deleted 0.1.0 tag and release from pypi, because the tag was not signed ;-) you could never trust it...

So for my TPM2 crate I was thinking to rename the project Git as tpm2_library and have sub-crates tpm2_call for protoco and tpm2_cli with a sub-command tpm2cli rc.

Is it acceptable to name for consistency sake the sub-crate directory as tpm2_cli but generate an executable as tpm2cli?

Root project’s name inherits from https://trustedcomputinggroup.org/resource/tpm-library-specification/

#Rust #rustlang #TPM2

I initiated my own #TPM2 #Rust crate partly because the output given by tpm2_rc_decode does not give back the mnemonic of a return code.

Here’s the example from its man page:

tpm2_rc_decode 0x1d5
tpm:parameter(1):structure is the wrong size

So I wrote my return code decoder, and here’s how it works with the previous example:

target/debug/examples/tpm2rc 0x1d5
TPM_RC_SIZE

The Git-repository is available here: https://gitlab.com/jarkkojs/tpm2_call

I’m not going to add any code this crate dealing with /dev/tpm0. Instead the plan is to implement command buffer builder and parser with similar high-level ideas as I’ve done in the #Linux #kernel.

Still cannot believe this: I could reserve account name "jarkko" from #pypi, and it is the year 2024. #python #python3

I think #Zola is my favorite tools so far that spans from the #Rust ecosystem: a single binary static web generator.

For a non-web person like me it is easy to grasp. I got a page quickly created that I can send to the employers in the early Fall.

Another earlier mentioned tool, which has someone real innovation embedded is of course #Typst :-)

Making forks of old craft is mostly counter-productive and causes unnecessary drift and divergence, so I oppose all the Rust fork garbage.

It is morally legit to be in opposition against software that is developed from toxic standing point, considering open source community overall. Being toxic against toxic is not toxic.

Someone complained that my home page, which should provide more information regarding recruitment leads to void so I put together this :-) I think it is good enough.

After I have finished with #TPM2 signing keys, I'll create a branch called p256k1 to my linux-tpmdd tree, and start doing a PoC of that #ECC curve...

I'll start with #ECDSA signature verification because that is secure without specialized hardware, and as of today #TCG is yet to support P256K1 in its #algorithm #registry.

Also this requires to implement the early version of Keccack-256 #hash algorithm because there are AFAIK padding differences with SHA-3.
