About:
Certstrap is a command-line tool designed to bootstrap your own Certificate Authority (CA) and generate signed certificates. It simplifies the process of creating the necessary keys and certificates for TLS communication without requiring complex configurations. This makes it ideal for securing internal networks, development environments, and automated infrastructure workflows.

Key Features:

Automated CA bootstrapping
Simple certificate signing requests (CSR)
Generates private keys and signed certificates
Zero-configuration approach

Use Cases:

Securing internal microservices communication
Setting up TLS for development environments
Automating certificate generation in CI/CD pipelines

Alternatives:

openssl – OpenSSL is a comprehensive cryptographic toolkit but requires more manual steps and configuration compared to certstrap's streamlined workflow.
easyrsa – Easy-RSA is another CA management tool, often used for OpenVPN, but certstrap is more lightweight and focused on general TLS certificate generation.
