Cypher¶

Overview¶

Cypher at its core is a secure Key/Value store. But what makes cypher useful is the ability to securely store or generate credentials to connect to your instances. Not only are these credentials encrypted but by using a cypher you don’t have to burn in connection credentials between instances into your apps.

Cypher keys can be revoked, either through lease timeouts or manually. So even if somebody were to gain access to your keys you could revoke access to the keys and generate new ones for your applications.

Keys can have different behaviors depending on the specified mountpoint.

Mountpoints¶

password

Generates a secure password of specified character length in the key pattern (or 15) with symbols, numbers, upper case, and lower case letters (i.e. password/15/mypass generates a 15 character password).

tfvars

This is a module to store a tfvars file for terraform app blueprints.

secret

This is the standard secret module that stores a key/value in encrypted form.

uuid

Returns a new UUID by key name when requested and stores the generated UUID by key name for a given lease timeout period.

key

Generates a Base 64 encoded AES Key of specified bit length in the key pattern (i.e. key/128/mykey generates a 128-bit key)

vault

Configures an integration between Morpheus and a Hashicorp Vault server. See below for additional configuration instructions.

Key lease times are entered in seconds and default to 32 days (2764800 s).
- Quick Time Reference:
- Day: 86400
- Week: 604800
- Month (30 days): 2592000

Creating Cypher Keys¶

Navigate to Services - Cypher and select “+ ADD KEY”
Configure one of the following types of Keys:

Password¶

A Cypher password generates a secure password of specified character length in the key pattern (or 15) with symbols, numbers, upper case, and lower case letters (i.e. password/15/mypass generates a 15 character password).

Key

Pattern “password/character_length/key”

Example: password/10/mypassword

Value

Leave the Value filed blank for a password, as it will be generated.

Lease

Enter lease time in seconds (ex. 604800 for one week)

Save changes and the password will be generated and available for use.

If your user role has Cypher: Decrypt permissions, a “DECRYPT” button will be available in the Cypher section to view the generated password.

To delete the password key, select Actions > Remove and confirm.

tfvars¶

A mountpoint to store tfvars files for Terraform App Blueprints.

Key

Pattern “tfvars/key”

Example: tfvars/my-aws-account

Value

The values for your tfvars file to be encrypted

Lease

Enter lease time in seconds (ex. 604800 for one week)

Click SAVE CHANGES and the stored values will be available for use.

Note

You may also see Cloud profiles stored at the tfvars mountpoint. They will have a key pattern like: “tfvars/profile/cloud/$cloudCode/variables”. Terraform Cloud profiles are created on the Cloud detail page (Infrastructure > Clouds > selected Cloud) under the Profiles tab. They allow Terraform apps and specs to be provisioned across multiple Clouds that require differed tfvars. See the Cloud profiles page for more.

Secret¶

A Cypher secret is the standard secret module that stores a key/value in encrypted form.

Key

Pattern “secret/key”

EXAMPLE: secret/mysecret

Value

Add the secret value to be encrypted

Lease

Enter lease time in seconds (ex. 604800 for one week)

Save changes and the secret will be encrypted and available for use.

If your Morpheus user role has Cypher: Decrypt permissions, a “DECRYPT” button will be available in the Cypher section to view the secret.

To delete the secret, select Actions > Remove and confirm.

UUID¶

A Cypher UUID Returns a new UUID by key name when requested and stores the generated UUID by key name for a given lease timeout period.

Key

Pattern “uuid/key”

Example: uuid/myuuid

Value

Leave the Value filed blank for UUID, as it will be generated.

Lease

Enter lease time in seconds (ex. 604800 for one week)

Save changes and the UUID will be generate and available for use.

If your user role has Cypher: Decrypt permissions, a “DECRYPT” button will be available in the Cypher section to view the generate UUID.

To delete the UUID, select Actions > Remove and confirm.

Key¶

A Cypher Key generates a Base 64 encoded AES Key of specified bit length in the key pattern (i.e. key/128/mykey generates a 128-bit key).

Key

Pattern “key/bit_length/key”

Example: key/256/mykey

Value

Leave the Value filed blank for key, as it will be generated.

Lease

Enter lease time in seconds (ex. 604800 for one week)

Save changes and the AES Key will be generate and available for use.

If your user role has Cypher: Decrypt permissions, a “DECRYPT” button will be available in the Cypher section to view the generate AES Key.

To delete the UUID, select Actions > Remove and confirm.

Vault¶

Use this mountpoint to store Cypher secrets in a Hashicorp Vault server backend rather than Morpheus. Additionally, you can call secrets stored in Vault from this Cypher mountpoint even if they are only saved there and not listed in the Morpheus Cypher UI. This requires installation and configuration of the Hashicorp Vault plugin. See the YouTube video embedded in this section for more information on adding the plugin, configuration, and a demonstration of its capabilities.

Note

It’s recommended that you use a long-lived token as attempts to call Vault-stored values into Tasks will stop working if the token is no longer good. In such a case you’d have to obtain a new token, delete the Cypher entry with the old token, and create a new one to restore functionality once again. Using a long-lived token will prevent the need to do this often.

Key: Pattern “vault/<engineMount>/<secretPath>/data/<key>” (ex. vault/KV2/secret/data/morpheus/lab)
Value: Enter your key/value pair here in valid JSON (ex. {“hello”: “world”} )
Lease: Enter lease time in seconds (ex. 604800 for one week)

Click SAVE CHANGES. The example BASH script below onboards the value stored in Vault from the secret/data/morpheus/lab mountpoint:

from_vault="<%= cypher.read('vault/KV2/secret/data/morpheus/lab') %>"

echo $from_vault

Using Cypher Keys in Scripts¶

To use a cypher Key in a script, use the following syntax:

<%=cypher.read('var_name')%>

Example: PASSWORD=<%=cypher.read('secret/myuserpassword')%>

Note

You can reference the original owner of a workflow so that keys can be used in a subtenant. Example PASSWORD=<%=cypher.read('secret/myuserpassword')%> could be changed to PASSWORD=<%=cypher.read('secret/myuserpassword',true)%> within a library or a workflow and the true means OWNER true. This will keep that key in the master tenants cypher store.
