I want to secure data for my NodeJs+Express+Mongodb website :

  • ABI
  • Contract address
  • Infura.io API key

Those data are very important because if an attacker can change them, it can steal ETH from my user.

Is there a way to run NodeJs with ABI+Contract address encrypted, and decrypt them with a passphrase ? Or can I store a file with this 2 data that need root access to be modified ?

This is incorrect. Only exposing a private key can lead to lost assets.

ABI and contract address are already public information and there is no point to encrypt them.
