Linux/Ubuntu

Required tools

KIRA requires the installation of two tools, Cosign and Bash-utils, in order to secure the network and simplify the execution of various tasks.

Cosign

cosign​

All KIRA Release Files are signed using sigstore cosign tool. Cosign is a digital signature utility that is used to verify the authenticity and integrity of a file. When a file is signed with a digital signature, it provides a way to verify that the file has not been tampered with, and also to verify the identity of the person or entity who signed the file. It is used in Kira to sign and verify the authenticity of data, such as proprietary tools, binaries and scripts.

Add KIRA’s public key

# Add key to env
echo "export KIRA_COSIGN_PUB=\"$KIRA_COSIGN_PUB\"" >> /etc/profile

Bash-utils

https://github.com/KiraCore/tools/releases​

Bash-utils is a collection of utility functions and aliases for Bash shell scripts developed specifically for KIRA to streamline and simplify the process of executing tasks within the network. It provides various functions for managing environment variables, displaying information, and handling errors.

The prerequisite to securely install BU is COSIGN tool that will guarantee the integrity of the files. It MUST be installed and KIRA’s public key added before proceeding.

Always source /etc/profile with . /etc/profile when starting a new terminal to use BU. 

Bash

Copy

# assume root permissions
sudo -s && . /etc/profile

# Install essential dependencies
apt-get install -y wget

# Define version of BU you want to install
TOOLS_VERSION="v0.3.42"

# Download BU script
if [ -z "$KIRA_COSIGN_PUB" ] ; then
  echo "ERROR: KIRA_COSIGN_PUB variable is not set. Please refer to cosign installation to add KIRA's public key path as variable."
  exit
fi && \
cd /tmp && FILE_NAME="bash-utils.sh" && rm -rfv ./$FILE_NAME ./${FILE_NAME}.sig && \
 UBUNTU_AGENT="Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/90.0.4430.85 Safari/537.36" && \
 wget --user-agent="$UBUNTU_AGENT" "https://github.com/KiraCore/tools/releases/download/$TOOLS_VERSION/${FILE_NAME}" -O ./$FILE_NAME && \
 wget --user-agent="$UBUNTU_AGENT" "https://github.com/KiraCore/tools/releases/download/$TOOLS_VERSION/${FILE_NAME}.sig" -O ./${FILE_NAME}.sig

# Verify cosign release
cosign verify-blob --key "$KIRA_COSIGN_PUB" --signature "/tmp/${FILE_NAME}.sig" "/tmp/$FILE_NAME" --insecure-ignore-tlog --insecure-ignore-sct

# Install BU
chmod +x ./$FILE_NAME && ./$FILE_NAME bashUtilsSetup && ./etc/profile

# Verify version of BU 
bu bashUtilsVersion
