AES decrypt in postman

sample code:

var CryptoJS = require("crypto-js"); 
let secretKey = 'yourSecretKey'; 

function decrypt(aesStr, key) { 
    return CryptoJS.AES.decrypt( 
        aesStr, 
        CryptoJS.enc.Utf8.parse(padding(key)), 
        { 
            mode: CryptoJS.mode.ECB, 
            padding: CryptoJS.pad.Pkcs7 
        } 
    ).toString(CryptoJS.enc.Utf8) 
} 

function padding(key) { 
    return key.padEnd(32, '\0'); 
} 

//decrypt("encryptedData", secretKey)

var CryptoJS = require("crypto-js");

let secretKey = 'yourSecretKey';

function decrypt(aesStr, key) {

return CryptoJS.AES.decrypt(

aesStr,

CryptoJS.enc.Utf8.parse(padding(key)),

{

mode: CryptoJS.mode.ECB,

padding: CryptoJS.pad.Pkcs7

}

).toString(CryptoJS.enc.Utf8)

}

function padding(key) {

return key.padEnd(32, '\0');

}

//decrypt("encryptedData", secretKey)

Here we choose AES-256 to encrypt / decrypt the secure information. When using AES, the length of the secretKey is important. The length of secretKey in AES-128 is 16 bits, and in AES-256 is 32 bits.

And in our case, the length of secretKey is no enough. So we will use the function padding to fill in the missing length.
