# Jenkins Credentials Decryptor

Command line tool for decrypting and dumping Jenkins credentials.

### What is this all about

Jenkins stores encrypted credentials in the `credentials.xml` file or in `config.xml` under folders. 
To decrypt them you need the `master.key` and `hudson.util.Secret` files.  

All files are located inside Jenkins home directory:

    $JENKINS_HOME/credentials.xml 
    $JENKINS_HOME/secrets/master.key
    $JENKINS_HOME/secrets/hudson.util.Secret
    $JENKINS_HOME/jobs/example-folder/config.xml - Possible location

### Compatibility

I've tested this on Jenkins 1.625.1 and 2.141

### Run using a binary

Mac:

    brew install hoto/repo/jenkins-credentials-decryptor

Mac or Linux:

    curl -L \
      "https://github.com/hoto/jenkins-credentials-decryptor/releases/download/1.2.0/jenkins-credentials-decryptor_1.2.0_$(uname -s)_$(uname -m)" \
       -o jenkins-credentials-decryptor

    chmod +x jenkins-credentials-decryptor
    
Or manually download binary from [releases](https://github.com/hoto/jenkins-credentials-decryptor/releases).

Help:

    ./jenkins-credentials-decryptor --help
    ./jenkins-credentials-decryptor --version

SSH into Jenkins box and run:

    ./jenkins-credentials-decryptor \
      -m $JENKINS_HOME/secrets/master.key \
      -s $JENKINS_HOME/secrets/hudson.util.Secret \
      -c $JENKINS_HOME/credentials.xml \
      -o json
      
Or if you have the files locally:

    ./jenkins-credentials-decryptor \
      -m master.key \
      -s hudson.util.Secret \
      -c credentials.xml \
      -o json
      
### Run using docker
    
If you are worried about me sending your credentials over the network (I can assure you I don't do that) 
then run a container with disabled network:

From Jenkins box:

    docker run \
      --rm \
      --network none \
      --workdir / \
      --mount "type=bind,src=$JENKINS_HOME/secrets/master.key,dst=/master.key" \
      --mount "type=bind,src=$JENKINS_HOME/secrets/hudson.util.Secret,dst=/hudson.util.Secret" \
      --mount "type=bind,src=$JENKINS_HOME/credentials.xml,dst=/credentials.xml" \
      docker.io/hoto/jenkins-credentials-decryptor:latest \
      /jenkins-credentials-decryptor \
        -m master.key \
        -s hudson.util.Secret \
        -c credentials.xml \
        -o json

With files locally:

    docker run \
      --rm \
      --network none \
      --workdir / \
      --mount "type=bind,src=$PWD/master.key,dst=/master.key" \
      --mount "type=bind,src=$PWD/hudson.util.Secret,dst=/hudson.util.Secret" \
      --mount "type=bind,src=$PWD/credentials.xml,dst=/credentials.xml" \
      docker.io/hoto/jenkins-credentials-decryptor:latest \
      /jenkins-credentials-decryptor \
        -m master.key \
        -s hudson.util.Secret \
        -c credentials.xml \
        -o json
        
### Build the binary yourself

If you are worried about executing a random binary from the internet then:

    git clone https://github.com/hoto/jenkins-credentials-decryptor.git
    make build
    
Binary will be in the `bin` folder.

### Example output

Json output format:

    $ ./jenkins-credentials-decryptor \
           -m master.key \
           -s hudson.util.Secret \
           -c credentials.xml \
           -o json
          
    [
      {
        "description": "Vault admin",
        "id": "vault-admin",
        "username": "admin",
        "password": "9cy7Mbw@1Omm7db@q6eP3k62Wm*ev#",
        "scope": "GLOBAL"
      }
    ]

Text output format:
 
    $ ./jenkins-credentials-decryptor \
           -m master.key \
           -s hudson.util.Secret \
           -c credentials.xml \
           -o text
          
    0
            description: Vault admin
            id: vault-admin
            username: admin
            password: 9cy7Mbw@1Omm7db@q6eP3k62Wm*ev#
            scope: GLOBAL
