spudw2k 231 Posted April 9, 2020 (edited) So, for a long time we've (my work) been using a very poor practice when sharing encrypted email attachments. (step 1, send an email with an encrypted zip; step 2, send the password in a separate email). In order to make exchanging encrypted attachments more secure, I put this tool together. It generates a Password based on a (pre-shared) Key (shared manually via a secure channel), and a Passphrase. The Passphrase is sent along with the encrypted zip and the tool uses the Key & Passphrase to re-generate the password used to encrypt / decrypt the zip. The password is generated by calculating a hash based on the Key and Passphrase, then coverts the first 20 bytes of the produced hash into a human-friendly password. It also uses the CryptProtectData and Unprotect functions put together by funkey to save the Key (per user) in the registry.
