Answer 1

Phew... after 40 minutes of decoding, I am finished (don't worry, though, it was a lot of fun, I haven't done it since I was a little kid and played gang warfare with the other kids):


UPON REACHING THE HUT I RAPPED, AS WAS MY CUSTOM, AND GETTING NO REPLY, SOUGHT FOR THE KEY WHERE I KNEW IT WAS SECRETED, UNLOCKED THE DOOR, AND WENT IN. A FINE FIRE WAS BLAZING UPON THE HEARTH. IT WAS A NOVELTY, AND BY NO MEANS AN UNGRATEFUL ONE.

How I did it: The key is to look at the short words. For example, we have one-letter-words in the code: "p" and "t". Those can only mean "a" and "I" - you only have to work out which is which. Then look at the two letter words, what could they be, what would make sense? The three letter words... we often have "tqo" after a comma, and t means a or i... so tqo is probably "AND". After working out one letter after another, set them into the rest of the text, and look if you can guess more words.

A helpful method while you're working: When you think you've worked out a new letter, always copy and paste the text before you try it - like that, you can always come back to a former version if you have been on the wrong track.

a million. separation from religious actuality 2. undesirable karma or adverse conditioning 3. cloth bias in the direction of selfishness universal i might say a egocentric act when you consider that this ends up in suffering and disharmony. all absolutely everyone seems to be sinful would nicely be translated into all of us have egocentric dispositions. Sin that separates humanity from God would nicely be translated into lack of wisdom or falseness that separates us from actuality, and motives worry that separates us from love. Any concept in any faith would nicely be translated into uncomplicated words; even though (a million) it relies upon on the context what the which ability is (2) it relies upon on the objective audience what terminology or examples might clarify it the suitable to that person's gadget (3) some structures don't have as sparkling a term for a concept as yet another, the comparable way with language, as an occasion, that the French term for "deja vu" would not have an English equivalent. in case you have different words or questions you would be able to digital mail me and that i might incredibly want to talk to you. This topic pastimes me plenty because of the fact i've got confidence it holds the main to international peace if we are in a position to translate, interpret and mediate throughout the time of religious and cultural lines. i think of it incredibly is a significant skill or concept to understand if the international is going to progression.

It takes considerable statistical analysis of a keyword cipher, using a frequency table of the letters in the message, just to get the length of the keyword. IF you have enough ciphertext, IF letter distribution in the cleartext was not unusual, etc. Difference between keyword and block ciphers is not really clear. See link. Good luck.
