If you need to configure TypeScript local environment, please visit our step-by-step tutorial for TypeScript:
Source Code
// import module module
import { MindLake } from 'mind-lake-sdk';
(async () => {
const mindLake = await MindLake.getInstance("YOU OWN APP KEY"); // replace to your own appKey
// connect to MindLake."5" is example of Goerli Testnet chainId
const chainId = "5"
const res1 = await mindLake.connect(chainId);
if(res1.code !== 0) {
return
}
// create a table
const dataLake = mindLake.dataLake;
const res2 = await dataLake.createTable("table_encrypted", [{columnName: 'id', type: DataType.int4, encrypt: true}, {columnName: 'name', type: DataType.text, encrypt: true}], ["id"]);
if(res2.code !==0) {
return
}
// encrypt data
const cryptor = mindLake.cryptor;
const res3 = await cryptor.encrypt(1, 'table_encrypted.id');
const res4 = await cryptor.encrypt("Alice", 'table_encrypted.name');
if(res3.code !==0 || res4.code !== 0) {
return
}
// insert encrypted data
const sql = `insert into table (id, name) values ('${res3.result}', '${res4.result}')`;
const res5 = await dataLake.query(sql);
console.log(`${sql} >>>`, JSON.stringify(res5));
if(res5.code !== 0){
return
}
//query encrypted data;
const selectSql = `select * from table_encrypted`;
const res6 = await dataLake.query(selectSql);
if(res6.code === 0) {
const columnList = res6.result.columnList;
for (const row of res6.result.data) {
for (const index in row) {
const encryptData = row[index];
const column = columnList[index];
const decryptRes = await cryptor.decrypt(encryptData);
console.log(`${column} decrypt data >>> `, decryptRes.result);
}
}
}
})();
Execution Output:
insert into table_encrypt (id, name) values ('\xa00a0e01876d340832195bdf03ad5d18fe92355e62fdc823a650a3bbab064de2c55586be', '\x5c3a0f01fd8bfc4ef7ea3848f80e011d433b81e2e544975157556d75bad76c3b4865b0ea') >>> {"code":0,"result":null}
id decrypt data >>> 1
name decrypt data >>> tom
