private key of SSL certificate

To create a certificate, first we need to fill a CSR and in CSR we have to place our public key and that key pair can be generated by different ways in different devices. To do ssh, we run command (crypto key generate RSA modules 1024) and generate the key pair.

Now with the help of this command we are generating public and private key for SSH which will help in encryption but the same key can be placed in CSR and from that CSR we can generate a certificate. Is it correct?

Where is the private key stored? I know the private key is very sensitive data but still if I am a server admin of a server or a firewall and want to see the private key then how can we check that? is there is a command for that?

Does Mordenkainen’s Private Sanctum prevent Devil’s Sight from working?

I could compare it to this question about whether the Devil’s Sight invocation allows one to see into Hunger of Hadar, but that question has an easy answer, due to the ‘blinded’ condition it affects the person inside with. However, the spell Mordenkainen’s Private Sanctum does not give the ‘blinded’ effect- it merely states that, in one of its properties:

The barrier of the warded area appears dark and foggy, preventing vision (including darkvision) through it.

Override WP Class Private Function

I’m new to community, I think you experts can help me in this. I have plugin installed and i want to its overwrite one function which is in class

    <?php    class wf_fedex_woocommerce_shipping_admin{  private function wf_user_permission($  auto_generate=null){  $  current_minute=(integer)date('i');         if(!empty($  auto_generate) && ($  auto_generate==md5($  current_minute) || $  auto_generate==md5($  current_minute+1) ))         {             return true;         }         $  current_user = wp_get_current_user();         $  user_ok = false;         $  wf_roles = apply_filters( 'wf_user_permission_roles', array('administrator', 'shop_manager') );          if ($  current_user instanceof WP_User) {             $  role_ok = array_intersect($  wf_roles, $  current_user->roles);             if( !empty( $  role_ok ) ){                 $  user_ok = true;             }         }         return $  user_ok; } } ?> 

I want to rewrite if so WP will use my custom instead of plugin I need a single change in new function ( I mean i just need pass ‘subscriber’ in array )

$  wf_roles = apply_filters( 'wf_user_permission_roles', array('administrator', 'shop_manager', 'subscriber') ); 

We can read the ssh private key with less id_rsa

I created an ssh key with the command ssh-keygen -t rsa -b 4096 -C "myname@myemail.com".

I put a passphrase.

It created two files : id_rsa and id_rsa.pub .

I am surprised because, when I do less id_rsa , I can read the key without there being a request for my passphrase. There is no word “encrypted” in the text.

I thought it was possible because the passphrase was not requested for me and only me but, if I copy the id_rsa file in the /home of another user, the result is the same: this user can see the key and the word “encrypted” does not appear.

I specify that I had to give reading rights with chmod but I don’t understand: why the passphrase is not requested?

Thank you a lot!

How to keep a Cloud-hosted trading algorithm private? Encryption?

Are there any reliable ways of protecting a cloud-hosted trading algorithm from being seen/copied – for example, by people working at a company who are hosting an algo (like QuantConnect, Quantopian, AWS, GoogleCloud, etc.)?

This seems like a potential risk to me – even though I’ve seen these companies saying that they take privacy and users’ intellectual property seriously.

Are there any best practices – like encryption? (And any reliable methods/specifics on encrypting a trading algo?) Or does one need to create their own server to keep an algo private?

Thanks for any guidance.

Why AWS distributes private key to address authentication problem?

AWS provides access to EC2 by downloading the private key(.pem) into management host that connects to EC2.

AWS uses openssl tool

Key providers generally provide public key but not private key, because with keypairs, one can encrypt either with public key or private key and decrypt with other key, as shown below:

$   openssl genrsa -out mykey 2048  $   cp mykey privatekey  $   openssl rsa -in mykey -pubout -out publickey   $   rm mykey  $   # Encrypt with public key  $   echo "the cat sat on the mat" | open ssl rsautl -encrypt -pubin -inkey publickey > ciphertxt  $   # cat cipher.txt  $   # cat cipher.txt | openssl rsautl -decrypt -inkey privatekey  

1) Why AWS distributes private key instead of public key? for secure communication…

2) Key pair is mainly to secure communication on the wire, but not authenticate user, to access a resource in AWS.

ssh -i something.pem user@ec2-public-dns-name

How does distribution of a key solve authentication problem? key can be stolen by any wrong person…Why AWS allow ssh login to EC2 without a password?

Storage of SSL private key in load balancer VS HSM

I have a setup whereby the SSL certificates are terminated at the load balancer (i.e. Load balancer to web server is in plaintext). In order to do the SSL termination, the private key is stored on the load balancer itself. I do have a HSM in a data center.

I was told by security guys that best practice is to store the private key in a HSM.

I have read Should SSL be terminated at a load balancer? and I understand that there is nothing wrong in terminating SSL encryption at the load balancer.

However, should the private keys be stored in the load balancer itself (from a security perspective)? Are there any technical challenges in storing the SSL private keys in a central HSM instead?
