About this project

This repository contains the Dockerfile for the mkpasswd image. This image allows you to generate secure passwords using the mkpasswd command.

Available Docker Images

Use the latest tag to get the latest stable release of the image.

Usage

This Docker container allows you to generate passwords using mkpasswd from the whois package with customizable options.

Running the Container

You can run this Docker container directly using the command line. By default, it uses SHA-512 as the hashing method.

docker run --rm -it serversideup/mkpasswd

This command will output a salted hash which you can use directly.

Customizing Password Generation

Specifying a Method

To specify a different hashing method, you can provide the --method option followed by the method name.

docker run --rm -it serversideup/mkpasswd --method=md5crypt

Available methods

Method Name	Hash
sha512crypt	SHA-512
sha256crypt	SHA-256
md5crypt	MD5
descrypt	standard 56 bit DES-based crypt(3)

You can always run the -m help command to view all available methods.

docker run --rm -it serversideup/mkpasswd -m help

Adding Salt

To add a specific salt, use the -S option followed by your desired salt value.

docker run --rm -it serversideup/mkpasswd --method=sha-512 -S mysalt

This command uses SHA-512 with a custom salt, enhancing the security of the generated hash.

Defaults

The default behavior without any additional arguments is to generate a salted hash using the SHA-512 method. If no specific salt is provided, mkpasswd automatically generates a random salt.

Examples

Here are some examples of how to use this Docker image:

• Generate a default SHA-512 salted hash:

  docker run --rm -it serversideup/mkpasswd

• Generate a hash using MD5 without a salt:

  docker run --rm -it serversideup/mkpasswd --method=md5crypt

• Generate a hash using SHA-512 with a specified salt:

  docker run --rm -it serversideup/mkpasswd --method=sha-512 -S mysalt

These examples should help you get started with generating passwords securely using the Docker container.
