Install

npm i aws-md5-of-message-attributes

Usage examples:

const { md5OfMessageAttributes } = require("aws-md5-of-message-attributes");

const simpleAttribute = { attribName1: { DataType: "String", StringValue: "attribValue 1" } };
md5OfMessageAttributes(simpleAttribute); // 19e27d4e946b072f3f58da80d94fd778

const withCustomAttributeType = { customNumberTypeAttrib: { DataType: "Number.float", StringValue: "4563442423554324324264524243.32543234" } };
md5OfMessageAttributes(withCustomAttributeType); // 9fe1b90bbd9965bdf77bac517c7d2495

const binaryAttribute = { binaryAttribute: { DataType: "Binary", BinaryValue: Buffer.from("Hello binary world!").toString("base64") } };
md5OfMessageAttributes(binaryAttribute); // 31a92b15d92f8db860eda32aceb656c3

const multipleAttributes = {
  attribName1: { DataType: "String", StringValue: "attribValue 1" },
  customNumberTypeAttrib: { DataType: "Number.float", StringValue: "4563442423554324324264524243.32543234" },
  binaryAttribute: { DataType: "Binary", BinaryValue: Buffer.from("Hello binary world!").toString("base64") },
};
md5OfMessageAttributes(multipleAttributes); // c932db14a896c663f83c260297d594ff
