Hyperledger Fabric SDK for node.js

Class: MSP

MSP

MSP is the minimal Membership Service Provider Interface to be implemented to manage identities (in terms of signing and signature verification) represented by private keys and certificates generated from different algorithms (ECDSA, RSA, etc) and PKIs (software-managed or HSM based)

new MSP(config)

Setup the MSP instance according to configuration information
Parameters:
Name Type Description
config Object A configuration object specific to the implementation. For this implementation it uses the following fields:
`rootCerts`: array of Identity representing trust anchors for validating signing certificates. Required for MSPs used in verifying signatures
`intermediateCerts`: array of Identity representing trust anchors for validating signing certificates. optional for MSPs used in verifying signatures
`admins`: array of Identity representing admin privileges
`signer`: SigningIdentity signing identity. Required for MSPs used in signing
`id`: {string} value for the identifier of this instance
`orgs`: {string} array of organizational unit identifiers
`cryptoSuite': the underlying module:api.CryptoSuite for crypto primitive operations

Methods

deserializeIdentity(serializedIdentity, storeKey)

DeserializeIdentity deserializes an identity
Parameters:
Name Type Description
serializedIdentity Array.<byte> A protobuf-based serialization of an object with two fields: mspid and idBytes for certificate PEM bytes
storeKey boolean if the user should be stored in the key store. Only when false will a promise not be returned
Returns:
Promise for an Identity instance or or the Identity object itself if "storeKey" argument is false
Type
Promise

getSigningIdentity(identifier)

Returns a signing identity corresponding to the provided identifier
Parameters:
Name Type Description
