Encryption
gocrypt: a tiny AES-GCM file encryption CLI
A small Go command-line tool to encrypt and decrypt files with AES-128 or AES-256 in GCM mode
Sometimes you just need to encrypt a file. Not set up a key management system, not learn the gpg command line again, not pull a heavy dependency — just turn secrets.txt into secrets.bin with a key you control. That’s the niche gocrypt fills for me.

A Docker image wrapping gitlab-backup with AES-GCM encryption and Kubernetes CronJob deployment for automated, secure GitLab backups to S3
gitlab-backup2s3: Encrypted GitLab Backups to S3, with Kubernetes Support
Source code: github.com/sgaunet/gitlab-backup2s3 Helm chart: github.com/sgaunet/helm-gitlab-backup2s3
In the previous article, I covered gitlab-backup, a CLI tool for exporting GitLab projects and groups as portable archives. It handles the export, the restore, and supports both local and S3 storage natively.
But for production backup workflows — especially in a Kubernetes environment — you often want more: scheduled execution, optional encryption at rest, and a container image that bundles everything together. That’s exactly what gitlab-backup2s3 brings to the table.
