CBOR is a concise binary data format inspired by JSON and MessagePack. CBOR is defined in RFC 8949 (December 2020) which obsoletes RFC 7049 (October 2013). CBOR is an Internet Standard by IETF. It's used in other standards like WebAuthn by W3C, COSE (RFC 8152), CWT (RFC 8392), CDDL (RFC 8610) and more. Reasons for choosing CBOR vary by project. Some projects replaced protobuf, encoding/json, encoding/gob, etc. with CBOR. For example, by replacing protobuf with CBOR in gRPC.

Here is yet another example. There is no need to do it in a for loop. You can use the pseudocolumn 0 (check help pseudocolumns) and lc var (check help linecolor variable) for setting the color.

If you are on linux try: pip3 install cose and then python3 your_file.py

The values in your output are base64-encoded, but you expect them in hex. See Base64 decode snippet in C++ for help with decoding in C++. Or see this example from the jsoncons documentation.

Gitlab ant.java.version is 11 but I want to build the project using another version

Asked 2021-Oct-19 at 12:36

So I'm using gitlab and I have a java project that's built on gitlab VM using a .gitlab-ci-yml file.

I have this problem where we have to change the java version the project is build with (current java 11).

So adding in build.xml this: will print 11.

I've tried to change it specifying in javac the source and target but if the target is not specified, it will not build it using another java version, and if it is specified, it will return an error:

Also using will return the same error.
So I'm not sure if basically adding my own ant tool and java version into the package and force it to use that one will work, I don't know how to do this.

Here is the build.xml file and also the .gitlab-ci.yml

UPDATE: .gitlab-ci.yml was updated. Now the error seems to be the following, having the below .gilab-ci.yml file: Unable to locate package adoptopenjdk-17-hotspot

According to the information provided in the comments, you have Java 14.0.1 on your GitLab runner. Since this Java version is used to launch ant and its tasks, it cannot compile code with a "17" target version.

To make a long story short, you'll need a newer Java version on your runner.

The simplest way of doing this is probably by using a pre-built image that contains it:

After a while I came up with the following solution. The $x5c field contains a list of certificates, all in binary form. I wrote the folowing converter to create a ready-to-use certificate in PEM format, which does the following:

base64 encode the binary data
break lines after 64 bytes
add BEGIN and END markers (also note the trailing line-break on the end certificate line)

I didn't managed to reproduce your issue but I was able to deploy your function in a Debian environment by following the next steps:

I run the following command firebase init functions (I picked TS and selected yes in all options)
cd functions
npm install cbor
npm install @google-cloud/iot
Copied your function inside the directory functions/src/index.ts
I modified the.eslintrc.js.
I run firebase deploy --only functions

In the .eslintrc.js I added the following lines in the rules section:

Install cbor

fxamacker/cbor supports Go 1.12 and newer versions. Init the Go module, go get v2, and begin coding.
🛡️ Use Go's io.LimitReader to limit size when decoding very large or indefinite size data. Import using "/v2" like this: import "github.com/fxamacker/cbor/v2", and it will import version 2.x as package "cbor" (when using Go modules). Functions with identical signatures to encoding/json include: Marshal, Unmarshal, NewEncoder, NewDecoder, (*Encoder).Encode, (*Decoder).Decode. If default options are acceptable, package level functions can be used for encoding and decoding. If you need to use options or CBOR tags, then you'll want to create a mode. "Mode" means defined way of encoding or decoding -- it links the standard API to your CBOR options and CBOR tags. This way, you don't pass around options and the API remains identical to encoding/json. EncMode and DecMode are interfaces created from EncOptions or DecOptions structs. For example, em, err := cbor.EncOptions{...}.EncMode() or em, err := cbor.CanonicalEncOptions().EncMode(). EncMode and DecMode use immutable options so their behavior won't accidentally change at runtime. Modes are reusable, safe for concurrent use, and allow fast parallelism. 💡 Avoid using init(). For best performance, reuse EncMode and DecMode after creating them. Most apps will probably create one EncMode and DecMode before init(). There's no limit and each can use different options. Both em.Marshal(v) and encoder.Encode(v) use encoding options specified during creation of encoding mode em. A TagSet is used to specify CBOR tags. TagSet and all modes using it are safe for concurrent use. Equivalent API is available for DecMode. The empty curly braces prevent a syntax highlighting bug on GitHub, please ignore them. The keyasint, toarray, and omitempty struct tags make it easy to use compact CBOR message formats. Internet standards often use CBOR arrays and CBOR maps with int keys to save space.
