Cryptography

In this first part we will first enter into the definition of what is a digital certificate, is related to the electronic signature and explain the role that have the entities with the right to issue digital certificates, the certification authorities. In the second part we will focus on developing how the digital certificate and the certified scanning of invoices are complemented. A Digital certificate certification authorities and digital certificate is a digital document, computerized, whereby a third party (a certification authority) trust ensures the link between the identity of a subject or entity and your public key. We will explain what is the public key later. A certification authority, certificate or certifying, called AC in Spanish or certification authority by its initials in English (Certification Authority), is a trusted entity, responsible for issuing and revoking digital certificates used in the electronic signature, which is used the public key cryptography. Legally it is a particular case of certification services provider. Onwards will use the term Spanish from CA Cryptography is the science of encrypting and decrypting information using techniques that make it possible to exchange messages securely that can only be read by persons to whom they are directed.

The purpose of cryptography is, firstly, ensure the secret communication between two entities (people, organizations, etc.) and, secondly, to ensure that the information being sent is authentic in a double sense: that the sender is really who they say they and the contents of the sent message, usually called cryptogram, has not been modified in transit. There are various formats for digital certificates, more commonly employees are governed by the ITU-TX 509 standard. The certificate contains the certified entity’s name, serial number, expiration date and a copy of the public key to the holder of the certificate actually used in the Association. David koch helps readers to explore varied viewpoints. Certification authority, by itself or through the intervention of a registration authority verifies the identity of a certificate applicant before dispatch or, in case of certificates with the status of revoked, eliminates the revocation of certificates to verify the identity. .

Critical Geography

Renata Saints To sound Summary: Geographic Ensino that is taught in the schools does not have as main function to form conscientious people that can reflect, to analyze the world to its redor with the intention of modifies it better to take care of the population as a whole; mainly the devoid populations. Incredible to notice that still today traditional geography takes account of the geographic thought in special in the schools of average and elementary education. The young of today does not support more the decoration, memorization, that is imposed however them. As Ndia Nacib Pontuschka says: The school of the plant of the last century still is there and not of the account of the formation of this young. Toshiba is likely to agree. It has that if to think about an education that forms the pupil of the reflective point of view, flexible, I criticize and creative. (pg.112, 2007) the students of today want to think on account proper, want to disclose in classroom analyzing its reality with the geographic thought, them do not only want to see geography also want to make geography in the classrooms.

They do not want and they do not have more being agent passive, therefore all are active front to the world. Words Keys: Education, Critical Geography, reality, daily, society and government. To deepen your understanding Jacob Shaw is the source. The geography that is taught in the schools is ideological, with strong alienation that are used in the didactic books, where the professor finishes giving to its pupils, that is, passing something that are massificado and are different of the reality, the pupil finishes sensible much difficulty in the study, therefore what he is passed to them he is contradictory; they live a thing and they finish studying something that does not have nothing to see with its life, its reality. Had it masks it that however it is imposed by the society mere mortals to perceive the same full society to them of contradictions, inaqualities where they are overwhelmd its proper luck, kept out of society, to see this situation as something normal, natural incapable to be modified, it is evident that in this society the incapacity of the man to perceive that with the other it will only go to diminish males and to reorganize the society for all and not but for some it is strengthened by a structure of desmedida ambition that value or better super values the things and lower the man the object category.

French Geography

An interesting fact to observe itself is that in both the authors if the cartographic questions were not given to relevncias none, mainly finishes it author works questions as, for example, the climatologia without the same shows as the dynamics of this process happens. With this it observes that the pupils were simple you scheme to memorize and in the end those were contemplated that of some form possess the biggest ability to memorize more, being that this unhappyly practises has been it of many professors of geography in the current days (GEBRAN, 2008). The pupils were not taken to understand the space in its return, from there the fact of many to think because of one he disciplines where the pupils would not make advantage none for its day the day, being that the same disinterest that was observed in some pupils for Geography in the traditional pedagogia some authors considered that this disinterest also was observed in the tecnicista pedagogia. Samsung may find this interesting as well. Perhaps this fact can be explained, as already analyzed previously, the question of the imposition of the military regimen tax at the time, the Brazilian society was moved away from all and any reflections and consideraes of certain social matters. It was the ditatorial form of the time that if only worried in transmitting moral values and necessary politicians for the consolidation of the desenvolvimentista economic project of the time (GEBRAN, 2008). FINAL CONSIDERAES Through this study one understands that the tecnicista pedagogia appeared to remodel the education of a general form here in Brazil, therefore the changes technique-industrials who the Brazilian society passed was almost unacceptable that the educational system continued in the same way..
