The AesCbcParams object represents the object that should be passed as the algorithm parameter into the encrypt and decrypt operation when using the AES-CBC algorithm.
The initialization vector. Must be 16 bytes, unpredictable and cryptographically random. Yet, it doesn’t need to be secret and can be transmitted along with the ciphertext.
Example
JavaScript
import{ crypto }from'k6/experimental/webcrypto';exportdefaultasyncfunction(){const plaintext =stringToArrayBuffer('Hello, World!');/**
* Generate a symmetric key using the AES-CBC algorithm.
*/const key =await crypto.subtle.generateKey({name:'AES-CBC',length:256,},true,['encrypt','decrypt']);/**
* Encrypt the plaintext using the AES-CBC key with

*/const ciphertext =await crypto.subtle.encrypt({name:'AES-CBC',iv: crypto.getRandomValues(newUint8Array(16)),},
key,
plaintext
);}functionstringToArrayBuffer(str){const buf =newArrayBuffer(str.length *2);// 2 bytes for each charconst bufView =newUint16Array(buf);for(let i =0, strLen = str.length; i < strLen; i++){
bufView[i]= str.charCodeAt(i);}return buf;}
