11.0.1 "Alonzo Compatible"
Release PR: https://github.com/Emurgo/cardano-serialization-lib/pull/500
A fix of the min-ada calculation to be compatible with Alonzo for now (until the mainnet forks)
This is a library that implements the CIP-0008 message signing spec for the Cardano blockchain.
The library is composed of structs for (de)serializing the CBOR defined in CIP-0008/COSE which lays at the core of the protocol, mostly defined in
lib.rs, as well as many helper utilities for more specific cases useful to CIP-0008. These are mostly in
builders.rs for building the CBOR structures specific to certain algorithms.
It can be used from both rust or compiled to wasm as all public code works with
There are no rust crates/npm packages uploaded yet, but these will come in the future.
In the meantime to build a wasm package we can run one of
npm run rust:build-nodejsfor nodejs targeted wasm
npm run rust:build-browserfor browser targeted wasm
npm run asm:buildfor conversion for asm.js
and for use from rust simply use the lib that resides in
It is important to read the CIP-0008 spec to properly understand how to use this library. As per CIP-0008/COSE, signing is done via constructing a
SigStructure and then signing this with the proper keys. This can be simplified via the use of the
COSESignBuilder (for multiparty signing) /
COSESign1Builder (for single signer) builders. Encryption is not yet supported by this library but will be in the future. An example node.js (wasm option) project that signs a message with a Cardano address exists in the
/example/ directory which has detailed comments describing each step.
This is a library that implements the [CIP-0008](https://github.com/cardano-foundation/CIPs/blob/master/CIP-0008/README.md) message signing spec for the Cardano blockchain.
