    CIP14-JS

    On the Cardano blockchain, native assets are uniquely identified by both their policy id and asset name. Neither the policy id nor the asset name are intended to be human-readable data. CIP14 introduces an asset fingerprint which is a short(er) and human-readable identifier for assets that user can recognize and refer to when talking about assets.

    More specifically, CIP14 defines a user-facing asset fingerprint as a bech32-encoded blake2b-160 digest of the concatenation of the policy id and the asset name.

    This package is a Typescript implementation of CIP14

    Install

    npm i @emurgo/cip14-js --save

    Usage

    const AssetFingerprint = require('@emurgo/cip14-js');
    
    // initialize class with policyId, assetName
    const assetFingerprint = AssetFingerprint.fromParts(
      Buffer.from('1e349c9bdea19fd6c147626a5260bc44b71635f398b67c59881df209', 'hex'),
      Buffer.from('504154415445', 'hex'),
    );
    
    const fingerprintHash = assetFingerprint.hash();
    const bech32Fingerprint = assetFingerprint.fingerprint();
    // initialize class with bech32
    const assetFingerprint = AssetFingerprint.fromBech32('asset1rjklcrnsdzqp65wjgrg55sy9723kw09mlgvlc3');
    
    const fingerprintHash = assetFingerprint.hash();
    const prefix = assetFingerprint.prefix();
