Have you ever forgotten the password to login to one of your many online accounts? It happens to me all the time so I save all my passwords to a file, encrypt it, and have a shell script to decrypt, search and spit the plain password whenever I don't remember the password. This is great when I am at home where I have access to my script and my encrypted password file. However, if I don't remember a password to a site when I am not at home, it is a problem. So I exposed a simple public interface on my webserver to securely decrypt my passwords online from anywhere. Feel free to use this tool to encrypt/decrypt anything (passwords, email, or just any text) and share a per message passphrase to other person to decrypt the message to its original content. Don't worry no one will be able to read unless you give them your passphrase. You can save the encrypted content (see a sample below) anywhere like google docs, dropbox, skydrive, or usb stick etc so you can easily access it anywhere. Feel free to use the tool (it is at the link below). There are many password manager tools like lastpass, keepass etc available freely that does similar things but the only difference is, here you control how you safeguard your encrypted file and in addition, you have simple web access to encrypt/decrypt any arbitrary text.
It is perfectly safe to store the encrypted message anywhere in your laptop/desktop as it will be encrypted with strong AES-256 cipher. Whenever you need to see the message content, all you need to remember is the passphrase you used to encrypt it. To get an idea, decrypt the sample content below using the passphrase 'th1s 1s coo1' without the quotes if you are interested to see how it works.
