Decrypt AES Key with RSA

Decrypt an AES Key with an RSA Private Key

The decryptAESKeyWithRSA performs asymmetric decryption using an RSA Private Key and the RSA-OAEP algorithm. The permissions are requested with the help of the Arweave Wallet (Window Object) in a browser environment if no wallet or use_wallet is passed. The node environment expects Arweave JWK to be passed.
Installation of ArConnect is suggested for successful use of this function in a browser environment.
Basic Syntax
The function is called as follows:
import { decryptAESKeyWithRSA } from 'arweavekit/encryption';
​
const decryptedAESKey = await decryptAESKeyWithRSA({params});
Input Parameters
The following params are available for this function and they must be passed in as an object:
key: Uint8Array : The encrypted AES key received from the encryptAESKeyWithRSA function.
wallet: ArWallet(optional): A value of type JWKInterface or use_wallet can be passed. If use_wallet or nothing is passed to this param, it expects ArConnect to be installed to run the decryption successfully.
Example
// In a browser environment, use_wallet or nothing can be passed.
const wallet = "use_wallet"
// In a node environment, Arweave wallet JWK can be passed.
const wallet = JSON.parse(fs.readFileSync('wallet.json').toString());
​
const decryptedAESKey = await decryptAESKeyWithRSA({
    key: Uint8Array,
});
This decrypts the provided AES Key using the RSA-OAEP algorithm.
Returned Data
The function call returns the following data:
{
    decryptedKey: string,
}
decryptedKey: string : The AES key decrypted using an RSA Public Key returned as a Base64 string.
