Configure self signed certificate on a locally hosted website

-

 1. create a private key

cd /etc/ssl/aureusapps

sudo openssl genrsa -des3 -out aureusapps.key 2048


2. Create a self signed certificate to use as root CA

sudo openssl req -x509 -new -key aureusapps.key -sha256 -days 1825 -out aureusapps.pem

-x509: Specifies that the certificate is to be self-signed rather than signed by a Certificate Authority (CA). This option is used for generating a root or self-signed certificate.

-new : generate new certificate request

-noenc : if a private key is created it will not be encrypted

-key : provides the private key for signing a new certificate or certificate request

-sha256 : Specifies SHA-256 as the hashing algorithm


3. Install root certificate

 sudo trust anchor aureusapps.pem


4. Creating CA-Signed Certificates for Your Dev Sites

    1. Create private key for site

        sudo openssl genrsa -out memeslab.aureusapps.dev.key 2048

    2. Create certificate signing request CSR

        sudo openssl req -new -key memeslab.aureusapps.dev.key -out memeslab.aureusapps.dev.csr

    3. create an X509 V3 certificate extension config file

authorityKeyIdentifier=keyid,issuer

basicConstraints=CA:FALSE

keyUsage = digitalSignature, nonRepudiation, keyEncipherment, dataEncipherment

subjectAltName = @alt_names


[alt_names]

DNS.1 = memeslab.aureusapps.dev


    4. Sign certificate request using CA private key
sudo openssl x509 -req -in memeslab.aureusapps.dev.csr -CA aureusapps.pem -CAkey aureusapps.key -CAcreateserial -out memeslab.aureusapps.dev.crt -days 825 -sha256 -extfile memeslab.aureusapps.dev.ext


5. Update apache SSL config

    SSLCertificateFile /etc/ssl/aureusapps/memeslab.aureusapps.dev.crt

    SSLCertificateKeyFile /etc/ssl/aureusapps/memeslab.aureusapps.dev.key

Flutter - Create Image Container with Round Corners and Splash Effect

-
Image
Introduction In this article I'm going to explain you about how image with round corners and splash effect is created using Flutter widgets. Before doing some coding, let's see how images are loaded in Flutter and what the splash effect means. Images in flutter In flutter apps, we can load images from network, assets (App resources) or from the file system. Loading images from network is very easy task in flutter using Image.network constructor. Image.network( 'https://raw.githubusercontent.com/flutter/website/master/src/_includes/code/layout/lakes/images/lake.jpg', ) If you want to load images from network and cache it for offline usage, you can use CachedNetworkImage widget. You need to add cached_network_image dependency to use it. Click here to see installation instructions. CachedNetworkImage( placeholder: CircularProgressIndicator(), imageUrl: '

AVR Analog Comparator

-
Image
Introduction AVR Analog comparator can be used to compare two analog inputs. The Analog Comparator compares the input values on the positive pin AIN0 and negative pin AIN1. When the voltage on the positive pin AIN0 is higher than the voltage on the negative pin AIN1, the Analog Comparator Output, ACO is set. the comparator can trigger a separate interrupt, exclusive to the Analog Comparator. We can select Interrupt triggering on comparator output rise, fall or toggle. Following is a block diagram of comparator and it's logic. Analog Comparator block diagram Registers ACSR (Analog Comparator Control and Status Register) is an 8-bit register which contains configuration bits for Analog Comparator. ACSR (Analog Comparator Control and Status Register) ACIS0, ACIS1 (Analog Comparator Inter
