Keywhiz vs Strongbox: What are the differences?

Keywhiz: A system for distributing and managing secrets. Keywhiz is a secret management and distribution service that is now available for everyone. Keywhiz helps us with infrastructure secrets, including TLS certificates and keys, GPG keyrings, symmetric keys, database credentials, API tokens, and SSH keys for external services — and even some non-secrets like TLS trust stores. Automation with Keywhiz allows us to seamlessly distribute and generate the necessary secrets for our services, which provides a consistent and secure environment, and ultimately helps us ship faster; Strongbox: A secret manager for AWS. Strongbox is a CLI/GUI and SDK to manage, store, and retrieve secrets (access tokens, encryption keys, private certificates, etc). Strongbox is a client-side convenience layer on top of AWS KMS, DynamoDB and IAM. It manages the AWS resources for you and configure them in a secure way.

Keywhiz and Strongbox can be categorized as "Secrets Management" tools.

Some of the features offered by Keywhiz are:

• Keywhiz Server provides JSON APIs for accessing and managing secrets. It is written in Java and based on Dropwizard.
• KeywhizFs is a FUSE-based file system, providing secrets as if they are files in a directory. Transparently, secrets are retrieved from a Keywhiz Server using mTLS with a client certificate.
• Presenting secrets as files makes Keywhiz compatible with nearly all software. Outside of Keywhiz administration, consumers of secrets only have to know how to read a file.

On the other hand, Strongbox provides the following key features:

• Serverless
• Simple access model
• Encryption

Keywhiz and Strongbox are both open source tools. Keywhiz with 2.09K GitHub stars and 166 forks on GitHub appears to be more popular than Strongbox with 244 GitHub stars and 21 GitHub forks.
