Amazon EC2 key pairs and Linux instances - Amazon Elastic

The application owner could then generate a public/private key pair for the client's "session", and then use the client's public key to encode their public key to the client. The public key is put in the certificate request in addition to some identifying information (such as website domain, address, and country). The public key can then be used to encrypt application secrets. So most of the current PKI system use a hierarchical validation system, where all the participant in the system must only know one of the parent in the hierarchy.

PKIjs is a pure JavaScript library implementing the formats that are used in PKI applications (signing, encryption, certificate requests, OCSP and TSP requests/responses). And as we assume that recovering the private key from the public key is hard, finding a secondary private key that matches a given public key can be considered hard as well. The below steps will show how to generate a SSH key, add it to the router, and then disable password authentication so that only the key-pair can be used to login. The parts of the key should each be a single hex number, while the cryptotext should be a sequence of bytes. The method getPortIdentifiers() returns an Enumeration of all the comm ports on the computer.

How to recover your EWT that you've sent by accident to a TRUST Wallet Ethereum address

How to recover your EWT that you've sent by accident to a TRUST Wallet Ethereum address
Here is a step by step guide on how to access your EWT tokens that you've sent by accident to TRUST wallet... assuming they were an ERC20 compatible token
First of all: relax, grab a coffee or tea... no need to freak out. If you follow this tutorial you'll restore your tokens and live a happy life ever after!
Disclaimer: This tutorial is made just to help, I'm not reliable for any loss. Make sure you'll know what you're doing and educate yourself about crypto and blockchain. Don't just copy paste what I say :)

STEP1: Get your private key out of TRUST

For some reason - not the most easy step. Trust wallet has a way to display private keys, but for Ethereum addresses you need to use advanced tricks.
>>>Get your private wallet seed (Recovery Phrase)
  • Go to Trust wallet app
  • Click the settings icon (bottom right)
  • Open wallets (top)
  • Press the info-icon next to your wallet where the Ethereum wallet is in that you've sent EWT to.
  • Click on 'Show Recovery Phrase'
TRUST wallet uses this seed to generate your Ethereum public and private address (BIP39 mnemonic)

STEP2: Generate your public/private key pair

This is an advanced step - make sure you do exactly as I state here.
>>>Open the BIP39 generator - Mnemonic Code Converter
>>>This tool works entirely in Javascript in your browser - but you need to make sure to take it offline
>>>Take your computer OFFLINE - I repeat - disconnect from Wifi

TRUST recovery phrase
  • Type the recovery phrase (words) you got from TRUST in the tool. Will look something like this:
  • Select ETH- Ethereum in the field Coin
ETH - Ethereum

  • Scroll all the way down... if all went well you'll find your TRUST Ethereum wallet in the list
The first address shown is my TRUST Ethereum wallet
>>> Get your private key and store it in a save place
  • Your private key is in the list (row 3) next to the Public key that is corresponding with your address. In this example it is 0x130a0caf1d4f4dd312c970b15a023abc17e0615fcb988ad08d3e3b9058af11a0 (oops, not on the screenshot)... so in the 'Derived Addresses' section
  • Close the tab and empty your clipboard
  • Go back online (WiFi)

STEP3: Access your EWT tokens

>>> We will now use Mycrypto.com as a EWT wallet interface
  • Download the desktop app (using private keys does not work in browser)
  • https://download.mycrypto.com/
  • Change the network to the EWC network (Left menu - last option)
EWC (Energy Web Chain)

  • Chose to recover wallet from Private Key
Chose the Private Key option
  • Unlock the wallet in MyCrypto
Click Unlock and enjoy the magic!

You are done! Live a happy life!

To those who keep promoting web-base client-side cryptographic services (i.e. crypto.cat, cryptb.in, crypty.ch, ...) on /r/netsec: Stop spewing your *crap* of a service. You are *very likely* not qualified to design crypto systems/services and quit wasting your talents on such half-ass efforts.

I'm tired of programmers who just learned about crypto that comes on to /netsec with their glass egos and boast about how people should use their "secure" crypto-bleh services. Dealing with crypto isn't a trivial thing and those knowledgeable with crypto realize there is more to it than banging out code and reusing crypto libs. And no, we're not here to give you free security audits, many here do it professionally and why should we waste our time with your flawed/insecure ideas.
I understand that no programmers write flawless code, but when it comes to crypto, the stakes are high. If you fucked up somewhere in the many fuckable realms of designing/developing crypto systems, you are doing a disservice to both your users and the infosec community. You can potentially expose your user's secret, put them in danger, and give a bad name to crypto.
I'm posting this since I've been having a on going argument with Kaepora in this deleted thread. I can't seem to get the point across that more considerations are needed before deciding to roll out with these services, it really bugs me that n00bs keep on insisting that web-based client-side crypto services are a great solution. This is the same redditor who rolled out with the now defunct cryptb.in. Even the crypto.cat tutorial video makes me cringe, Bob and Alice are better off sharing their public-keys before parting and communicate over GnuPG, that way they can use a trusted and mature program and encrypt just about anything digital, instead they are sharing symmetric-keys that could be compromised and using an untested service that the government could be sslstriping. The better idea is to teach the user to do it right the first time around, teach them how to use trusted+mature crypto suites.
As robozome pointed in the deleted thread, this article is just a few reasons why browser-based client-side crypto is a bad idea.
If you're an attention whoring InfoSec wannabe, stop whoring half-baked crypto ideas, go whore with some other ideas that is less dangerous. If you want well deserved attention, come out with novel exploits or new security paradigms. When you redesign or re-implement ideas that has already been well thought out (GnuPG, OpenSSL, etc), you're denying all those before you who put much more effort in crypto development and have considerably more experience than you have. Maybe its worth standing on the shoulders of giants rather than a dwarf standing alone.
Leave the designing and implementation of production cryptosystems to those who are actually qualified to do so. Experienced crypto specialists are few in numbers and a very small subset of infosec community. And if you want to join them, by all means you're welcome to do so, but the knowledge must be learned and don't be a hack.
If you want to practice developing of crypto systems, sure that's fine however you shouldn't push it onto the web, advertise it as a "secure" service and entice people unfamiliar with crypto into using it, this could very well lead the user to suffer unintended and potentially dangerous consequences.
Instead of wasting your effort on designing and developing flawed web-based client-side crypto systems, you're better off doing your homework on the proper way of using mature+trusted crypto systems and educating users on how to properly use it. Here's a tick list:

*tl;dr: Crypto n00bs can be dangerous.
** more junk rant; GnuPGP => GnuPG (thx, gbeier)
