Choosing a Password

The password you choose is the most important factor influencing the security of your files. This means that it is absolutely unacceptable to use weak passphrases, i.e. short or easy-to-guess ones. If your passphrase is in the dictionary, you are definitely in jeopardy.

It is highly recommended that you use a long and unusual passphrase containing upper and lower case letters, numbers, spaces, and punctuation marks, preferably something that you can easily remember but that others cannot guess. In other words "Letmein" or "My Name" are bad passphrases, while something like "is 1t TiMe to ch00z someth!ng bet-ter 4 you&me?" is good. It's also a good idea to mix your native language with foreign words and use non-English characters.
