Authorization

To generate the authorization token to access Veridata REST APIs, copy the below script to a script file on the linux box and edit the following parameters:

USERNAME="<username>"
This is the Veridata user created.
PASSWORD="<password>"
This is the password of Veridata user.
URL="http://<host>:<port>/veridata/v1/auth/login"
Host: Veridata

Server hostname port: Veridata Server port
Save and run the script, to generate the Veridata authorization token.

#!/bin/bash

# Function to generate MD5 hash
md5_hash() {
  echo -n "$1" | openssl dgst -md5 | awk '{print $2}'
}

# Variables
USERNAME="<userName>"
PASSWORD="<password>"
REALM=""
NONCE=""
QOP=""
CNONCE=$(openssl rand -hex 8)  # Random client nonce
OPAQUE=""
ALGORITHM="MD5"
URL="http://<host>:<port>/veridata/v1/auth/login"
API_URL="/v1/auth/login"

# First call to get digest details (WWW-Authenticate header)
response_headers=$(curl -s -I "$URL" | grep -i 'WWW-Authenticate-Custom')

# Extracting the necessary fields from the WWW-Authenticate header
REALM=$(echo "$response_headers" | grep -Eo 'realm="([^"]*)"' | cut -d'"' -f2)
NONCE=$(echo "$response_headers" | grep -Eo 'nonce="([^"]*)"' | cut -d'"' -f2)

OPAQUE=$(echo "$response_headers" | grep -Eo 'opaque="([^"]*)"' | cut -d'"' -f2)

# Generate HA1, HA2, and response based on Digest Authentication process
HA1=$(md5_hash "$USERNAME:$REALM:$PASSWORD")
HA2=$(md5_hash "GET:$API_URL")
NC="00000001"  # Nonce count
RESPONSE=$(md5_hash "$HA1:$NONCE:$NC:$CNONCE:$QOP:$HA2")

# Generate Authorization header
AUTH_HEADER="Digest username=\"$USERNAME\", realm=\"$REALM\", nonce=\"$NONCE\", uri=\"$API_URL\", algorithm=$ALGORITHM, qop=$QOP, nc=$NC, cnonce=\"$CNONCE\", opaque=\"$OPAQUE\", response=\"$RESPONSE\""
# Perform second call with Authorization header
curl -v -H "Authorization: $AUTH_HEADER" "$URL"
