Hash minute timestamp + userId on Node.js, Nativescript, and R

hash.node.js

// import createHash function from crypto (default Node.js library)
const { createHash } = require("crypto");

// get current date in UTC as ISO string and keep all chars up until minutes
// eg. 2019-10-14T17:40
const date = new Date().toISOString().slice(0, 16);

// get userId
const userId = "0000123";

// join both date and userId with no space in between
const hashable = [ date, userId ].join("");

// create a MD5 hash and digest it to hex
const hash = createHash("md5").update(hashable).digest("hex");

console.log(hash);

hash.ns.js

// import MD5 function from nativescript-md5 (https://www.npmjs.com/package/nativescript-md5)
const { MD5 } = require("nativescript-md5");

// get current date in UTC as ISO string and keep all chars up until minutes
// eg. 2019-10-14T17:40
const date = new Date().toISOString().slice(0, 16);

// get userId
const userId = "0000123";

// join both date and userId with no space in between
const hashable = [ date, userId ].join("");

// create a MD5 hash and digest it to hex
const hash = MD5.hashForString(hashable);

console.log(hash);

hash.R

# import digest library (default R-base library)
library(digest)

# get current date in UTC as ISO string and keep all chars up until minutes
# eg. 2019-10-14T17:40
date <- strftime(as.POSIXlt(Sys.time(), tz = "UTC"), "%Y-%m-%dT%H:%M")

# get userId
userId <- "0000123"

# join both date and userId with no space in between
hashable <- paste(date, userId, sep = "")

# create a MD5 hash and digest it to hex
hash <- digest(hashable, algo="md5", ascii = TRUE, raw = FALSE, serialize = FALSE)

print(hash)
