For symmetic encryption, you can use the following:
To encrypt:
openssl aes-256-cbc -salt -a -e -in plaintext.txt -out encrypted.txt
To decrypt:
We can generate a common CA certificate, and then each project can use this CA certificate to sign and issue a project certificate. Hence the CA certificate is needed to install as a trusted cert, and once the project is signed and issue using this CA cert, the new project certificate will be trusted via chain of trust policy.
Generate a CA key
openssl genrsa -out ca.key 4096
Generate a CA public key, ensure expiry date is exceeding the individual cert
