If the key is truly random, as large as or greater than the plaintext, never reused in whole or part, and kept secret, the ciphertext will be impossible to decrypt or break without knowing the key.

If a cryptographic hash function is well designed, it is computationally infeasible to reverse the function to recover a plaintext password.

If the ciphertext exhibits a frequency distribution very similar to plaintext, it is most likely a transposition.

If, however, a digit is corrupted in transmission, rather than added or lost, only a single digit in the plaintext is affected and the error does not propagate to other parts of the message.

If it is any smaller, more than one plaintext may encrypt to the same ciphertext.

If the plaintext redundancy is 0, then the unicity distance is infinite, and the system is unbreakable.

If plaintext is stored in a computer file ( and the situation of automatically made backup files generated during program execution must be included here, even if invisible to the user ), the storage media along with the entire computer and its components must be secure.

If an attacker knows the IV ( or the previous block of ciphertext ) before he specifies the next plaintext, he can check his guess about plaintext of some block that was encrypted with the same key before ( this is known as the TLS CBC IV attack ).

* The reason for diffusion is the following: If one changes one bit of the plaintext, then it is fed into an S-box, whose output will change at several bits, then all these changes are distributed by the P-box among several S-boxes, hence the outputs of all of these S-boxes are again changed at several bits, and so on.

If the running key is truly random, never reused, and kept secret, the result is a one-time pad, a method that provides perfect secrecy ( reveals no information about the plaintext ).

If c and r are known, the plaintext is then with.

If the input happens to fill up an entire block, a “ dummy block ” is added to accommodate the padding ; otherwise, the end of the input plaintext might be misinterpreted as padding.

If the plaintext length N is not a multiple of the block size L:

If the circumstances are faced frankly it is not reasonable to expect this to be true.

If his dancers are sometimes made to look as if they might be creatures from Mars, this is consistent with his intention of placing them in the orbit of another world, a world in which they are freed of their pedestrian identities.

If a work is divided into several large segments, a last-minute drawing of random numbers may determine the order of the segments for any particular performance.

If they avoid the use of the pungent, outlawed four-letter word it is because it is taboo ; ;

If Wilhelm Reich is the Moses who has led them out of the Egypt of sexual slavery, Dylan Thomas is the poet who offers them the Dionysian dialectic of justification for their indulgence in liquor, marijuana, sex, and jazz.

If he is the child of nothingness, if he is the predestined victim of an age of atomic wars, then he will consult only his own organic needs and go beyond good and evil.

If it is an honest feeling, then why should she not yield to it??

If he thus achieves a lyrical, dreamlike, drugged intensity, he pays the price for his indulgence by producing work -- Allen Ginsberg's `` Howl '' is a striking example of this tendency -- that is disoriented, Dionysian but without depth and without Apollonian control.

If love reflects the nature of man, as Ortega Y Gasset believes, if the person in love betrays decisively what he is by his behavior in love, then the writers of the beat generation are creating a new literary genre.

If he is good, he may not be legal ; ;

If the man on the sidewalk is surprised at this question, it has served as an exclamation.

If the existent form is to be retained new factors that reinforce it must be introduced into the situation.

If we remove ourselves for a moment from our time and our infatuation with mental disease, isn't there something absurd about a hero in a novel who is defeated by his infantile neurosis??

If many of the characters in contemporary novels appear to be the bloodless relations of characters in a case history it is because the novelist is often forgetful today that those things that we call character manifest themselves in surface behavior, that the ego is still the executive agency of personality, and that all we know of personality must be discerned through the ego.

If he is a traditionalist, he is an eclectic traditionalist.

If our sincerity is granted, and it is granted, the discrepancy can only be explained by the fact that we have come to believe hearsay and legend about ourselves in preference to an understanding gained by earnest self-examination.

If to be innocent is to be helpless, then I had been -- as are we all -- helpless at the start.

If a child loses a molar at the age of two, the adjoining teeth may shift toward the empty space, thus narrowing the place intended for the permanent ones and producing a jumble.

If, say, the Russians intended to stop Tom Jones' going to the pub, then Tom Jones would fight the Commies.

If " biweekly " is used in a conversation about a meeting schedule, it may be difficult to infer which meaning was intended.

If the fletching is not arranged to induce rotation, it will still improve accuracy by causing a restoring drag any time the arrow tilts away from its intended direction of travel.

If the software works as intended and without issues during normal use, one can reasonably extrapolate the same level of stability in production.

If he intended an attack along the Moselle the Duke must now turn west, but, instead, the following day the army crossed to the right bank of the Rhine, ( pausing to add 5, 000 waiting Hanoverians and Prussians ).

If the page's creator and reader are both assuming some platform-specific character encoding, and the server does not send any identifying information, then the reader will nonetheless see the page as the creator intended, but other readers on different platforms or with different native languages will not see the page as intended.

* If the offence fumbles ( a ball carrier drops the football, or has it dislodged by an opponent, or if the intended player fails to catch a lateral pass or a snap from centre, or a kick attempt is blocked by an opponent ), the ball may be recovered ( and advanced ) by either team.

If art was to appeal to sensibilities, Dada was intended to offend.

If, as seems likely from the name, these people were the continental remnants of the Jutish invaders of Kent, then it may be that the marriage was intended as a unifying political move, reconnecting different branches of the same people.

If the inhabitants of Palestine were ready for independence under a Class “ A ” mandate, then the Palestinian Arabs that made up the majority of the inhabitants of Palestine in 1922 ( 589. 177 Arabs vs. 83. 790 Jews ) could then logically claim that they were the intended beneficiaries of the “ Mandate for Palestine ” – provided one never reads the actual wording of the document:

If the required font files do not exist on the machine where the SVG file is rendered, the text may not appear as intended.

“ If we develop a better system for determining relevant causal relations so that we are able to choose actions that better produce our intended ends, it does not follow that we then must change our ethics.

If a feature was intended to be located from the center of the part, the operator needs to locate it from the center of the model, not, perhaps, from a more convenient edge or an arbitrary point, as he could when using " dumb " solids.

If the fuse was set correctly then the shell would break open, either in front or above the intended target, releasing its contents ( of musket balls ).

If a precondition is violated, the effect of the section of code becomes undefined and thus may or may not carry out its intended work.

If the machine address does not match the intended address for the data, the machine ignores the data.

If a message is intended for a computer partway down the line, each system bounces it along in sequence until it reaches the destination.

If so, Offa's intervention was probably intended to gain control of this relationship and take over the dominance of the associated kingdoms.

If he allowed too much time to elapse between the initial drafting of a passage and its later elaboration, he found that he could not remember how he had intended to orchestrate the draft.

If an airliner is defined as a plane intended for carrying multiple passengers in commercial service, the Russian Sikorsky Ilya Muromets was the first official passenger aircraft.

If the accused admits to having a motive consistent with the elements of foresight and desire, this will add to the level of probability that the actual outcome was intended ( it makes the prosecution case more credible ).
