go-iden3-client

go iden3 client is a library implementation for an iden3 identity client in go that also offers gomobile-friendly wrappers.

Test

• this library connects with the IdenityServer, so it will need a running IdentityServer.

go test ./...

Usage

// define a provider
providerParams := make(map[string]string)
providerParams["url"] = "http://127.0.0.1:25000/api/unstable"
provider := Provider{
        Type:   "remote",
        Params: providerParams,
}

// new BabyJubJub public key
kOpStr := "0x117f0a278b32db7380b078cdb451b509a2ed591664d1bac464e8c35a90646796"
var kOpComp babyjub.PublicKeyComp
err := kOpComp.UnmarshalText([]byte(kOpStr))
assert.Nil(t, err)
kOpPub, err := kOpComp.Decompress()

// create new keystore
ks := NewKeyStore()

// import key to keystore
err = ks.ImportKeyBabyJub(kOpPub)

// create new identity
id, proofKOp, err = provider.CreateIdentity(keyStore, kOp, nil)

// load identity
identity, err = provider.LoadIdentity(id, kOp, proofKOp, keyStore)

// add claims
err := identity.AddClaims([]*merkletree.Entry{c0, c1})

// get emitted claims
claims, err := identity.EmittedClaims()

// get received claims
claims, err := identity.ReceivedClaims()
