📦 Installation

Clone the repository and build the tool:

git clone https://github.com/Ar1ste1a/Dehasher.git
cd Dehasher
go build dehasher.go

---

🔰 Getting Started

To begin, clone the repository

git clone https://github.com/Ar1ste1a/Dehasher.git
cd Dehasher
go build dehasher.go

---

🛠️ Initial Setup

Dehasher requires an API key from Dehashed. Set it up with:

ar1ste1a@kali:~$ dehasher set-key <redacted>

---

🗄️ Database Configuration

Dehasher supports two database storage options:

1. Default Path (default): Stores the database at ~/.local/share/Dehasher/db/dehashed.sqlite
2. Local Path: Stores the database in the current directory as ./dehasher.sqlite

The Local Path option allows for separate databases for different projects or engagements.

To configure the database location:

# Use local database in current directory
./dehasher set-local-db true

# Use default database path
./dehasher set-local-db false

🔍 Crafting Queries

Simple Query

Dehasher can be used simply for example to query for credentials matching a given email domain.

# Provide credentials for domains matching target.com
dehasher api -D target.com -C

Simple Credentials Query

Dehasher can also be used to return only credentials for a given query.

# Provide credentials for emails matching @target.com
dehasher api -E @target.com -C

Multiple Match Query

Dehasher is capable of handling multiple queries for the same field.
This is useful for when you want to search for multiple domains, or multiple usernames.

# Provide credentials for domains matching target.com and target2.com, retrieving only credentials
dehasher api -D target.com,target2.com -C

Wildcard Query

Dehasher is capable of handling wildcard queries.
A wildcard query cannot begin with a wildcard.
This is a limitation of the Dehashed API. An asterisk can be used to denote multiple characters, and a question mark can be used to denote a single character.

# Provide credentials for emails matching @target.com and @target2.com
dehasher api -E @target?.com -C -W

Email Query

Dehashed has dictated that emails should be searched in the following format: email:target.name&domain:target.com. As such, to query an email, please use the following format (note, wildcard is not required but can be useful):

# Provide credentials for emails matching target.*@target.com
dehasher api -W -E 'target*' -D target.com

You may also query the domain and find emails as well

# Provide credentials for emails matching target.com
dehasher api -D target.com -C

Regex Query

Dehasher is capable of handling regex queries.
Simply denote regex queries with the -R flag. Place all regex queries in quotes with the corresponding query flag in single quotes.

# Return matches for emails matching this given regex query
dehasher api -R -E '[a-zA-Z0-9]+(?:\.[a-zA-Z0-9]+)?@target.com'

Output Text (default JSON)

Dehasher is capable of handling output formats.
The default output format is JSON.
To change the output format, use the -f flag.
Dehasher currently supports JSON, YAML, XML, and TEXT output formats.

# Return matches for usernames exactly matching "admin" and write to text file 'admins_file.txt'
dehasher api -U admin -o admins_file -f txt

🌐 WhoIs Lookups

Dehasher supports WHOIS lookups, history searches, reverse WHOIS searches, IP lookups, MX lookups, NS lookups, and subdomain scans. The WhoIs Lookups require a separate API Credit from the Dehashed API.

Domain Lookup

Dehasher can perform a domain lookup for a given domain. This provides a tree view of the domain's WHOIS information.

# Perform a WHOIS lookup for example.com
dehasher whois -d example.com

History Lookup

History Lookups require 25 credits. This is a Dehashed API limitation. The history lookup is immediately written to file and not displayed in the terminal or stored in the database.

# Perform a WHOIS history search for example.com
dehasher whois -d example.com -H

Reverse WHOIS Lookup

Dehasher can perform a reverse WHOIS lookup for given criteria.
This provides a list of all domains that match the given query.
The reverse WHOIS lookup is immediately written to file and not displayed in the terminal or stored in the database.

# Perform a reverse WHOIS lookup for example.com
dehasher whois -I example.com

IP Lookup

Dehasher can perform a reverse IP lookup for a given IP address.
This provides a list of all domains that match the given query.

# Perform a reverse IP lookup for 8.8.8.8
dehasher whois -i 8.8.8.8

MX Lookup

Dehasher can perform an MX lookup for a given MX hostname.
This provides a list of all domains that match the given query.

# Perform a reverse MX lookup for google.com
dehasher whois -m google.com

NS Lookup

Dehasher can perform an NS lookup for a given NS hostname.
This provides a list of all domains that match the given query. The picture below also includes the --debug global flag.

# Perform a reverse NS lookup for google.com
dehasher whois -n google.com

Subdomain Scan

Dehasher can perform a subdomain scan for a given domain.
This provides a list of all subdomains that match the given query.

# Perform a WHOIS subdomain scan for google.com
dehasher whois -d google.com -s

📊 Database Querying

Dehasher stores query results in a local database.
This database can be queried for previous results. This database also includes WhoIs Information and Subdomain Scan results, but does not include historical lookups.

Simple Query

It's possible to query the database using shorthand and without knowing any SQL at all.

The following queries the results table where username is not null, only showing the username, email and password columns.

You may also add in a simple query using the -q flag. The following displays a 'LIKE' clause on the email column.

Note the '%<clause>%' is still required.

Dehasher supports querying the database for previous results.
This is useful for when you want to query for specific information.

# Query the database for all results containing the word 'admin' in the username
dehasher query -t results -q "username LIKE '%admin%'"

Raw SQL Queries

Dehasher also supports raw SQL queries. This is useful for when you want to query for specific information.

# Query the database for all results containing the word 'admin' in the username
dehasher query -r "SELECT * FROM results WHERE username LIKE '%admin%'"

Query Options

Dehasher supports a number of query options. These options can be used to filter the results of a query.

# Query the database for all results containing the word 'admin' in the username
dehasher query -t results -q "username LIKE '%admin%'" -n username,email,password

Listing Tables and Columns

Dehasher supports listing all available tables and columns.
This is useful for when you want to query for specific information.

# List all available tables and columns
dehasher query -a

The current tables available for query are:

• results
  • Results from a dehashed query
• creds
  • Credentials parsed from dehashed results
• whois
  • Results from a whois record lookup
• subdomains
  • Subdomains discovered in a whois subdomain scan
• runs
  • Previous query runs to the dehashed API
• lookup
  • Results of any Whois NS, MX, or IP lookup

---

Exporting Results

Dehasher supports exporting results to a file.
This is useful for when you want to requery for specific information without touching the Dehashed API. The export subcommand supports all the same options as the query subcommand. The export subcommand also supports file naming and output format control.

# Export all results containing the word 'admin' in the username to a text file
dehasher export -t results -q "username LIKE '%admin%'" -o admins_file -f txt

🐛 Debugging

Dehasher uses the zap logging library for logging. The logs are stored in ~/.local/share/Dehasher/logs. The logs can be easily queried from the Dehasher CLI.

# Show the last 10 logs
dehasher logs -l 10

# Show logs from the last 24 hours
dehasher logs -s "last 24 hours"

# Show logs from the last 24 hours with a severity of error or fatal
dehasher logs -s "05-01-2025" -v error,fatal

Logs Dates

Dehasher utilized 'easy time' to determine the appropriate time for a given query.

You may also used dates mixed with easy time to perform queries.

The following formats are supported:

• last 24 hours
• last 2 days
• 30 minutes ago
• 45 seconds ago
• 1 week ago
• 05-01-2025
• 05/01/2025
• 05/01/25
• 05-01-25
• May 01, 2025
