bin.dec()
aes.dec(data, key) → { valid, data }Decrypts AES-256 data and validates its checksums.
Decrypt AES256 encrypted data received from peers. Keys are 256-bit values — derive one from a passphrase with bin.sha256(). Decrypted results include checksum validation via the valid flag.
The http and udp functions can also decrypt transparently (see setEnv("aes.key", …)).
Arguments
| Name | Type | Required | Default | Description |
|---|---|---|---|---|
| data | binary | yes | — | Encrypted data from bin.enc() or a peer. |
| key | binary | yes | — | The 256-bit key used to encrypt. |
Returns
object
{ valid, data } — valid is true when decryption succeeded and checksums match; data is the plaintext.
Example
let aesKey = bin.sha256("password");
let decrypted = bin.dec(encrypted, aesKey);
if(decrypted.valid){
let obj = JSON.parse(decrypted.data);
print(string(obj));
} else {
print("AES Decryption Failed.");
