A simple text file can be a flexible way of storing your ideas-you can add a date if you want to, and you can come back to the list and add notes later to expand on it. If you're thinking up new ideas all the time, you're going to want somewhere to put them.
#Get plain text wont open how to#
I recently wrote about how to come up with better ideas. If you'd rather store all that data yourself and not have it filling up an email account, you could use a text file to keep a running list of short letters to your children about their progress. I came across this idea on Hacker News, where a parent mentioned writing emails to their son every day. You won't get the extras of an app made for journalling, such as automatic weather data, tags, or adding images, but if your aim is to build the simple habit of penning some thoughts every day, plain text will more than suit your needs.Ī related idea is writing letters for your children to read when they grow up. There are some great apps for journalling now, but if you don't want to pay for yet another app just to hold your journal, a text file can work just as well. You don't need to fit in with any particular feature set-just try out different ways of planning your week and stick with what works. The great thing about using a text file for your weekly plan is that you have the flexibility to experiment. Once a week, usually on Mondays, I open a small text file named plan.txt and jot down my action plan for the week. I do both, as I need a robust system to keep track of everything, but a simple to do list for the week keeps me from getting overwhelmed. Even if you use a complicated task management app, you might still benefit from doing a simple weekly plan like this.
This allows him to investigate the attacked system in much more details.Computer scientist Cal Newport uses a text file to plan his week ( example above) so he can get more done. Instead of using one big block of text, it can choose the smaller one, receive its encrypted ciphertext and then based on the answer, choose another one, and so on. In this kind of chosen-plaintext attack, the intruder has the capability to choose plaintext for encryption many times. The most known chosen-plaintext attacks were performed by the Allied cryptanalysts during World War II against the German Enigma ciphers. After that he will be able to find the meaning of many intercepted encrypted messages, by simply comparing them with his own database entries. He can analyse the system behaviour and output ciphertext, based on any kind of input data.ĭuring breaking deterministic ciphers with the public key, the intruder can easily create a database with popular ciphertexts, for example with popular queries to the server. He can obtain more information about the secret key and about the whole attacked system, because he is able to choose any text to be processed by the cipher.
This is a rather comfortable situation for the attacker. He tries to acquire the secret encryption key or alternatively to create an algorithm which would allow him to decrypt any ciphertext messages encrypted using this key (but without actually knowing the secret key).
During the chosen-plaintext attack, a cryptanalyst can choose arbitrary plaintext data to be encrypted and then he receives the corresponding ciphertext.
