history

Project history and usage

shush is a Go command-line utility from REA Group for encrypting and decrypting small secrets with AWS Key Management Service.

Project history

REA Group developed shush as a small AWS KMS encryption and decryption tool. The official repository's copyright notice dates from 2019, and the project was implemented in Go with downloadable release binaries.

Adoption history

The official project publishes release binaries, documents installation with go install, and provides a direct Unix/Linux installation example. Its exec mode also supports container-entrypoint use, broadening it from an interactive encryption utility into a deployment-time secret injector.

How it is used

Pipe plaintext to shush encrypt with a KMS key ID, ARN, or alias, then pipe the Base64 ciphertext to shush decrypt. The exec subcommand decrypts KMS_ENCRYPTED_ environment variables and exposes the plaintext under names without that prefix before starting another command.

Why package nerds care

shush is representative of small cloud-native security utilities that wrap a managed key service in Unix pipes and environment-variable conventions. Its command-shim mode is particularly relevant to container and twelve-factor deployment workflows.

Timeline

1.5.5: Version used in the official binary-installation and container examples.

Related projects

AWS KMS provides the cryptographic service and AWS SDK credential chain. The official README also points to ssssh as a Ruby-compatible alternative and shows how AWS CLI plus base64 can reproduce the basic decrypt workflow.

Recommended review

Before unattended agent use, check whether the tool reads plaintext credentials, writes remote state, publishes artifacts, or shells out to plugins.
