This repository contains a CBOR AAR library and an Android application. The latter is only intended for testing and demonstrating the cryptographic functions of the CBOR library.
| Note that this document as well as the on-line API reference, mirror the "trunk". Releases come with release specific information which may differ considerably between versions. |
- Deterministic encoding support
- Diagnostic notation support including decoder
- Enveloped signature support
- Encryption support
- checkForUnread() for catching possible misunderstandings regarding protocol contracts
- URL-based object Id tag
The CBOR library API is described in: https://cyberphone.github.io/android-cbor/distribution/apidoc/org/webpki/cbor/package-summary.html. Note that Ed25519 only works on Android 13+ and that Ed25519 signatures cannot be validated, only generated. This is due to limitations in Android and will presumably be fixed in Android 15.
The rest of the library has been verified to work from Android 7 (API 24) and up.
To use the precompiled module, copy the AAR file located in
https://github.com/cyberphone/android-cbor/tree/main/distribution
to a libs folder in the application and then add the line
implementation files('libs/org.webpki-jlibcbor-1.1.2.aar')
to the dependencies section of the Gradle file.
The library source code is available in: https://github.com/cyberphone/android-cbor/tree/main/jlibcbor.
A feature-wise identical implementation can be tested on-line at: https://test.webpki.org/csf-lab/home.
See https://github.com/cyberphone/android-cbor/tree/main/RELEASE-NOTES.txt.
