The API key is a unique identifier that authenticates requests associated with your project for usage and billing purposes. You must have at least one API key associated with your project. Secret API keys should be kept confidential and only stored on your own servers. Your account’s secret API key can perform any API request to Stripe without restriction. Each account has a total of four keys: a publishable and secret key pair for test mode and live mode. Obtaining your API keys. Our free mobile-friendly tool offers a variety of randomly generated keys and passwords you can use to secure any application, service or device. Simply click to copy a password or press the ' Generate ' button for an entirely new set.

Keys are smaller – this, for instance, means that it’s easier to transfer and to copy/paste them; Generate ed25519 SSH Key. Here’s the command to generate an ed25519 SSH key: email protected: $ ssh-keygen -t ed25519 -C 'email protected' Generating public/private ed25519 key pair. Enter file in which to save the key (/Users/greys/.ssh.

Quick example

This example will show you how to create a Zone file to point the 'www.example.com' and 'example.com' addresses to the same IPV4 address and then associate your new Zone file with the domain.

To keep things simple and universal, the snippets use curl from the command line to make HTTP requests to the LiveDNS API. You can of course use any other tool to make the equivalent requests.

Step 1 - Get your API key

Start by retrieving your API Key from the 'Security' section in new Account admin panel to be able to make authenticated requests to the API.

Step 2 - Create your Zone file

Make a POST request to the /zones endpoint to create your Zone file.

You only need to set the name property to something that makes sense for you and let the platform use the default values for the rest (you can change them later if you want).

Example:

Note that the URI of the Zone file you have just created is available in the Location: header and that it includes the resource's uuid, which you can parse in a script.

Throughout these examples, the -D- flag is passed to curl to write the HTTP response headers to STDOUT.

Just a quick note - Shortcut access to a domain's zone

Note that if you don't want to handle zones, and simply want the shortestroute to modify a domain's zone, you can also access the zone records usingthe following shortcut, which is equivalent to accessing/zone/<uuid>/records:

Example:

More information is available below, in the Work with Domains section.

Step 3 - Create the DNS records

The LiveDNS API is pretty flexible and allows you to create DNS records in a few different ways. In this example, you'll use a single PUT request to the /zones/<uuid>/records endpoint to create two DNS records, described as JSON objects.

Example:

Now your zone file contains two A records that point www and @ to the same IP address, with TTL values of 3600 seconds (1 hour).

You can also overwrite the whole zone using text/plain data (following the a limited subset of the RFC 1035 master file format):

Step 4 - Associate the domain

Generate Sk Live Api Keywords

Now it's time to associate your domain, example.com, with this Zone file. In this example you'll use the /zones/<uuid>/domains/<domain> endpoint, as it offers the simplest possible code snippet, but you can find different ways to accomplish this in the API reference.

Example:

Step 5 - Change your nameservers

And with that you're ready to go. If you change the nameservers, this new zone will be live for the whole Internet to see. Before you do this, make sure you copy all the records from your current DNS service.

Each domain has a unique set of nameservers. You have to query our API to grab your set of nameservers:

Step 6 - setup automatic DNSSEC signing

By posting to /domains/<fqdn>/keys, you can create a DNSKEY and haveour servers automatically sign the zone for you:

Example:

You then have access to the key's DS and information by GETting the keyarray. Keys are accessed using their key_href like so:

Getting the key href:

Deleting the key:

WARNING: you should never delete a key if a DS is present at the registry, or still present in the caches, as it would make the zone 'security lame'. If you mistakenly do so, you can recover the key by using a PUT method on its uuid:

Step 7 - Adding extra security with a slave server

We strive to provide you with the best DNS service ever, but having allyour eggs in one basket is not best practice. Our servers will happilyaccept AXFR requests from slave configured with the right TSIG key. Bonus,they'll also send NOTIFY packets to the slaves you configured. We do notsupport pure IPv4 ACLs yet, you have to use TSIG, but it's pretty commonnowadays.

First, create a TSIG key - you might want to share it among multiple domainslater:

Creating a TSIG key:

Then, use the key uuid to authorize AXFRs on your domain like so:

Adding the TSIG key for AXFRs:

Now, if you also want to notify slave servers, you can add them to the domainconfiguration via the /axfr/slaves route like so:

Adding two slaves servers to the domain:

And voila, your domain is now replicated to a second host.

DNSSEC RRSIG records are generated along with NSEC3 records if youenabled DNSSEC.

Simply updating the zone records should generate a NOTIFY message to the configured slaves. We'll buffer that through a 30 seconds window to avoid notification storms.

Bonus, if you're setting up the slave on your own server, we provide you withconfiguration samples including the master servers IPs, and all the TSIGconfiguration.

Simply fetch the TSIG key from axfr/tsig and follow the config_samples dict for your software:

How To Generate ed25519 SSH Key

Generating ed25519 SSH Key

I’m hoping to reinstall my MacBook Pro 15” 2017 with a fresh macOS Catalina sometime soon, and part of preparations is testing my install methods (hello, brew!) and configuration files migration. Today I decided to setup a new SSH keypair.

What is ed25519?

ed25519 is a relatively new cryptography solution implementing Edwards-curve Digital Signature Algorithm (EdDSA).

Generate Sk Live Api Keyboard

I say relatively, because ed25519 is supported by OpenSSH for about 5 years now – so it wouldn’t be considered a cutting edge. Still, people are such creatures of habits that many IT professionals daily using SSH/SCP haven’t even heard of this key type.

Similarly, not all the software solutions are supporting ed25519 right now – but SSH implementations in most modern Operating Systems certainly support it.

Why ed25519 Key is a Good Idea

Compared to the most common type of SSH key – RSA – ed25519 brings a number of cool improvements:

• it’s faster: to generate and to verify
• it’s more secure
• collision resilience – this means that it’s more resilient against hash-function collision attacks (types of attacks where large numbers of keys are generated with the hope of getting two different keys have matching hashes)
• keys are smaller – this, for instance, means that it’s easier to transfer and to copy/paste them

Generate ed25519 SSH Key

Here’s the command to generate an ed25519 SSH key:

That’s it – this keypair is ready to be deployed to SSH servers, GitHub or any other service that can use them.
