Simple Passwords Management

Command line tools for Windows 10 to manage passwords stored in AES encrypted files.

Storage

Files with passwords can store any additional information: comments, empty lines, logins. Only following rules must be observed:

1. The line is divided into chunks using spaces
2. First chunk is tag that describes password
3. Second chunk is the password (so, it can't contain spaces)
4. Other chunks can be used as you wish

Example passwords.txt:

# Social Networks passwords file.

## Google
google.me PASSWORD [email protected] // No comments
google.mom PASSWORD // Mom's password
google.dad PASSWORD [email protected]


## Facebook
....

This file should be encrypted using openssl as passwords.aes with some secret password

openssl aes-256-cbc -salt -in passwords.txt -out passwords.aes
enter aes-256-cbc decryption password:

Note: You can also make the file base64-encoded by adding -a switch to the command above, to be able copy and paste its text content.

Strongly recommended to check encrypted file before next steps.

openssl aes-256-cbc -d -in passwords.aes

After it passwords.txt can be removed.

Usage

1. Create file with passwords as described in Storage section and encrypt it
2. Download copypass.bat and findpass.bat
3. Run following command, and enter secret password to output all tags, matching google substring:

C:\Users\user>findpass.bat passwords.aes google
google.me
google.mom
google.dad

4. Copy password by tag to system clipboard:

C:\Users\user>copypass.bat passwords.aes google.me

5. Paste it in form submit form and copy something else to reset clipboard value.

Note: this format can be used in Unix-based systems with aliases:

echo "alias findpass='function __findpass() { read -sp \"Enter password: \" PASS;echo;export PASS;openssl aes-256-cbc -d -in \$1 -pass env:PASS|grep \$2|awk \"{print \\\$1}\";unset PASS;unset -f __findpass; }; __findpass'" >> ~/.bashrc
echo "alias copypass='function __copypass() { read -sp \"Enter password: \" PASS;echo;export PASS;openssl aes-256-cbc -d -in \$1 -pass env:PASS|grep \$2|head -1|awk \"{print \\\$2}\"|xclip --clipboard;unset PASS;unset -f __copypass; }; __copypass'" >> ~/.bashrc

Management

Edit encrypted files using OpenSSL plugin for VIM.

Note: If your encrypted file is base64-encoded (openssl -a switch) you have to apply this patch to be able to edit the file using VIM:

$ sed -i -r -e 's/-([ed]) -salt/-\1 -a -salt/g' ~/.vim/plugged/openssl.vim/plugin/openssl.vim
