Methods
asArray
▸ asArray(): bigint[]
Returns
bigint[]
bigint[] - the command as an array
Notice
Returns this Command as an array. Note that 5 of the Command's fields are packed into a single 250-bit value. This allows Messages to be smaller and thereby save gas when the user publishes a message.

encrypt
▸ encrypt(signature, sharedKey): Message
Parameters
| Name | Type |
|---|---|
signature | Signature<SnarkBigNumber> |
sharedKey | EcdhSharedKey |
Returns
Notice
Encrypts this command along with a signature to produce a Message. To save gas, we can constrain the following values to 50 bits and pack them into a 250-bit value: 0. state index 3. vote option index 4. new vote weight 5. nonce 6. poll ID

sign
▸ sign(privKey): Signature<SnarkBigNumber>
Parameters
| Name | Type |
|---|---|
privKey | PrivKey |
Returns
Signature<SnarkBigNumber>
Notice
Signs this command and returns a Signature.

verifySignature
▸ verifySignature(signature, pubKey): boolean
Parameters
| Name | Type |
|---|---|
signature | Signature<SnarkBigNumber> |
pubKey | PubKey |
Returns
boolean
Notice
Returns true if the given signature is a correct signature of this command and signed by the private key associated with the given public key.

decrypt
▸ decrypt(message, sharedKey, force?): IDecryptMessage
Decrypts a Message to produce a Command.
Parameters
| Name | Type | Default value | Description |
|---|---|---|---|
message | Message | undefined | the message to decrypt |
sharedKey | EcdhSharedKey | undefined | the shared key to use for decryption |
force | boolean | false | whether to force decryption or not |
Returns
IDecryptMessage
Dev
You can force decrypt the message by setting force to true.
This is useful in case you don't want an invalid message to throw an error.

fromJSON
▸ fromJSON(json): PCommand
Deserialize into a PCommand instance
Parameters

|---|---|
json | IJsonPCommand |
Returns
a PComamnd instance
