To use

const { issue } = require("holonym-wasm-issuer")

// This script will convert to a safer version of thoe private key inside the modulus
const privateKey = crypto.randomBytes(32)

// The user generates a random secret and provides the issuanceNullifier which is set by 
// PoseidonHash(secret, 0x194ee5653c27cb200f64d0bd1ade2b4734e3341ea37712c6a5a4bd30870c33f1)
// 0x194ee5653c27cb200f64d0bd1ade2b4734e3341ea37712c6a5a4bd30870c33f1 is the public salt, a nothing-up-my-sleeve value equal to SHA256(\"Holonym Issuance\")
const issuanceNullifier = "123456789"

// Field 1 is some custom value the issuer wants to include in the credentials. If you want to include more values in `field1`, you can set `field1` to a hash of multiple values
const field1 = "5555555555555555555555555555"

// Field 2 is some custom value the issuer wants to include in the credentials. If you want to include more values in `field2`, you can set `field2` to a hash of multiple values
const field2 = "6666666666666666789"


issuer(privateKey, issuanceNullifier, field1, field)
