Strongly consider clearing your shell's session history of any sensitive information.


Bash writes the current session history to disk (~/.bash_history) at the end of the session.

  1. Tactical Approach: Clear a specific entry in the current session

     $ history
     666 cryptify --help
     667 cryptify encrypt ./myfile.txt -p mySecretKey
     $ history -d 667
     $ history -w
  2. Blunt Approach: Clear the entire current session history (in memory)

     $ history -c
  3. Nuclear Approach: Clear current and existing session history (in memory, and on disk)

     $ rm $HISTFILE
     $ history -c
     $ exit
     (open shell)
     $ cat $HISTFILE

Windows Command Prompt

Windows does not store history between command prompt sessions.

  1. However, for safety, consider decreasing the Buffer Size and Number of Buffers in the Properties menu before use.

  2. Per this configuration, Windows will only store the last command in the buffer.

  3. Once work with cryptify is complete, close the command prompt:

     C:\Users\[user]> cryptify encrypt ./myfile.txt -p mySecretKey
     C:\Users\[user]> exit

Windows PowerShell

  1. PowerShell's Clear-History command doesn't seem to work as advertised, which is designed to clear the current session's history.

  2. However, deleting PowerShell's history file does do the trick.

     PS C:\Users\[user]> cryptify encrypt ./myfile.txt -p mySecretKey
     PS C:\Users\[user]> del (Get-PSReadlineOption).HistorySavePath
     PS C:\Users\[user]> exit

Password Requirements

  1. Must contain at least 8 characters
  2. Must contain at least 1 special character
  3. Must contain at least 1 numeric character
  4. Must contain a combination of uppercase and lowercase
