migratePassToBitwarden.js

// migrating from password-store (aka pass) to bitwarden.
// by Simon Jones (2023)
//
// note: I do not use bitwarden, this is for you to use.
// this script assumes you have:
// 1. decrypted all of your password-store gpg encrypted files
// and put them in a folder named 'passDecryptedFiles'.
// 2. a directory structure as follows:
// ./
// ├ migratePassToBitwarden.js
// └ passDecryptedFiles/
//   ├ file1.gpg.txt
//   ├ file2.gpg.txt
//   ├ file3.gpg.txt
//   ├ file4.gpg.txt
//   ├ ...
//   └ fileN.gpg.txt
//
// good luck.
