A small script to encrypt files and directories using AES-256-GCM that uses a user provided password, hashed using SHA256, as the encryption key

Install dependencies

npm install

Running from npm script

npm start -- lock mypassword file.txt

To run from the encrypter command see Installation below

lock

Must be given a password and a relative path to a file or directory

Will ignore files with the .encrypted extension

unlock

Must be given a password and a relative path to a file or directory

Will ignore files without the .encrypted extension

Install dependencies

npm install

Build executable script

npm run build

A file named encrypter will now be in the project root. You can place this in any directory that is in your user PATH to execute from anywhere. For example I have the ~/bin directory in my PATH.

Running from installation

encrypter lock mypassword file.txt

There are some features / enhancements that I've day-dreamed about / would be nice to have, but the project hits all the points I need to utilize it, so they're just going to get listed out here.

• Encryption & signing to allow sending of files to an intended recipient using public / private keys
• Proper CLI features (help command, better error messaging, version command)
• Async encryption / decryption of directories, which is currently done synchronously
