Methods

name	type	Parameters Description	response
getMessageSharedSecret	function	1.myEd25519PrivateKey: string 2.targetUserPubkey: string 3.msg_timestamp: string	Promise:aesKey
aesGCMEncrypt	function	1.keyStr: string 2.iv: string 3.inputByteData: Uint8Array	Promise:encrypt
aesGCMDecrypt	function	1.keyStr: string 2.iv: string 3.encoded: Uint8Array	Promise:decrypt

GetMessageSharedSecret

const aesKey = await getMessageSharedSecret(
  myEd25519PrivateKey,
  targetUserPubkey,
  msg_timestamp
);

AesGCMEncrypt

const encrypt = await aesGCMEncrypt(keyStr, iv, inputByteData);

AesGCMDecrypt

const decrypt = await aesGCMDecrypt(keyStr, iv, encoded);

Example

export const App = () => {
  const getEncrypt = async () => {
