Authenticate with SessionSigs

Once you have obtained SessionSigs, you can replace where you provide an AuthSig with the SessionSigs object. Below are some examples using the Lit SDK.

Making Signing Requests

var unifiedAccessControlConditions = [
  {
    conditionType: "evmBasic",
    contractAddress: "",
    standardContractType: "",
    chain: "ethereum",
    method: "eth_getBalance",
    parameters: [":userAddress", "latest"],
    returnValueTest: {
      comparator: ">=",
      value: "10000000000000",
    },
  },
];

// Retrieving a signature
let jwt = await litNodeClient.getSignedToken({
  unifiedAccessControlConditions,
  sessionSigs,
});

Making Encryption Requests

var unifiedAccessControlConditions = [
  {
    conditionType: "evmBasic",
    contractAddress: "",
    standardContractType: "",
    chain: "ethereum",
    method: "eth_getBalance",
    parameters: [":userAddress", "latest"],
    returnValueTest: {
      comparator: ">=",
      value: "10000000000000",
    },
  },
];
const chain = "ethereum";

// encrypt
const { ciphertext, dataToEncryptHash } =
  await LitJsSdk.zipAndEncryptString(
    {
      unifiedAccessControlConditions,
      chain,
      sessionSigs,
      dataToEncrypt: "this is a secret message",
    },
    litNodeClient,  
  );

sessionSigs = await LitJsSdk.getSessionSigs({
  chain,
  litNodeClient,
  resourceAbilityRequests: []
});

const decryptedFiles = await LitJsSdk.decryptToZip(
  {
    unifiedAccessControlConditions,
    chain,
    sessionSigs,
    ciphertext,
    dataToEncryptHash,
  },
  litNodeClient,
);
const decryptedString = await decryptedFiles["string.txt"].async(
  "text"
);
console.log("decrypted string", decryptedString);
