For +" example: +" +" .des3 .aes .bf .bfa .idea .cast .rc2 .rc4 .rc5 (.bfa is base64 ASCII +" encoded blowfish.) +" +" This will turn off the swap file and the .viminfo log. The `openssl` command +" line tool must be in the path. +" +" == Install == +" +" Put this in your plugin directory and Vim will automatically load it: +" +" ~/.vim/plugin/openssl.vim +" +" You can start by editing an empty unencrypted file. Give it one of the +" extensions above. When you write the file you will be asked to give it a new +" password. +" +" == Simple Vim Password Safe == +" +" If you edit any file named '.auth.bfa' (that's the full name, not just the +" extension) then this plugin will add folding features and an automatic quit +" timeout. +" +" Vim will quit automatically after 5 minutes of no typing activity (unless +" the file has been changed). +" +" This plugin will fold on wiki-style headlines in the following format: +" +" == This is a headline == +" +" Any notes under the headline will be inside the fold until the next headline +" is reached. The SPACE key will toggle a fold open and closed. The q key will +" quit Vim. Create the following example file named ~/.auth.bfa: +" +" == Colo server == +" +" username: maryjane password: esydpm +" +" == Office server == +" +" username: peter password: 4m4z1ng +" +" Then create this bash alias: +" +" alias auth='view ~/.auth.bfa' +" +" Now you can view your password safe by typing 'auth'. When Vim starts all +" the password information will be hidden under the headlines. To view the +" password information put the cursor on the headline and press SPACE. When +" you write an encrypted file a backup will automatically be made. +" +" This plugin can also make a backup of an encrypted file before writing +" changes. This helps guard against the situation where you may edit a file +" and write changes with the wrong password. You can still go back to the +" previous backup version. The backup file will have the same name as the +" original file with .bak before the original extension. For example: +" +" .auth.bfa --> .auth.bak.bfa +" +" To turn on backups put the following global definition in your .vimrc file: +" +" let g:openssl_backup = 1 +" +" Thanks to Tom Purl for the original des3 tip. +" +" I release all copyright claims.
