Recommendation for encryption plugin (AES-256 / sensitive data)?

Hi everyone,

I’m looking for recommendations for a reliable, production-ready plugin to handle text encryption within my app workflows.

My goal is to encrypt sensitive strings (like external credentials/tokens or specific private data) before saving them to the database, and then decrypt them server-side when needed.

Ideally, I’m looking for something that uses industry-standard encryption (like AES-256) and runs smoothly on backend workflows.

Are there any specific plugins you’ve used and highly recommend for this?

Thanks in advance!
