Equivalent of OpenSSL base64 enc in Node.js (openssl enc -base64 -d -A)? -


there's api i'm working returns data that's gunzipped , double base64 encoded. i've tried using several of base64 libraries in npm no avail. doing each library's equivalent decodebase64(decodebase64(something)) fails due output encoding being faulty.

this work in shell: something | openssl enc -base64 -d -a | openssl enc -base64 -d -a | gunzip. i'm looking node.js approach behaves same something | openssl enc -base64 -d -a | openssl enc -base64 -d -a | gunzip.

the following libraries not work in situation: base64 base-64 js-base64

the solution find library can handle both string , binary representations of base64 (which mirrors openssl).

const forge = require('node-forge') const zlib  = require('zlib')  const pass1  = forge.util.decode64('sdrzsufbqufbqufbqunzcetrmezbstfnl1awrufbque=') const pass2  = forge.util.binary.base64.decode(pass1) const result = zlib.gunzipsync(new buffer(pass2)).tostring()  console.log(result) // true

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now
