Reasons for not Encrypting Data Essay Example for Free

Reasons for not Encrypting Data Essay Encryption of data involves using particular software such as PGP to put it in the form only understandable by the intended recipient. However, encryption does not fully guarantee the security of the data nowadays with introduction of sophisticated malwares by hackers. Most of the popular emails used –yahoo, Gmail, and hotmail- encrypts passwords and information on transit automatically and thus it more or less important to first encrypt your emails. For instance, yahoo applies SSL tools to encrypt all data. Using encryption software involves a lot time as one has to validate every email before sending it with a key. A person who has initiated the use of encryption service has to publish hi/her key so that other have access to it as well as other person’s public key. Besides, the key has to be unique and complex to mitigate possible hacking. Consequently, the recipient of the email must be using encryption software as well as have the necessary public and private key to decrypt the information. This means that communication with individuals who are not using encryption software is difficult. A situation whereby a person is the solitary user of software among the others could probably arise (Shankland, 2010). Additionally, key management is challenging to anyone who is not conversant with IT because of vulnerabilities to encryption, such as `brute force` cracking and `back doors`. It is via using lengthy keys and genuine software that can mitigate this although not totally (NetAction, 2001). According to Whitten (1999) if you are using encryption software, one is forced to back it up and some other of user’s action are delicate in that they are irreversible. Thus, a high risk of losing valuable data and they include deleting private key accidentally, publicizing one’s key accidentally, revoking a key accidentally, and forgetting a pass phrase. If a private key is deleted, it is totally gone whereas forgetting lengthy key for instance â€Å"S411!! y are: #1 i/\/! mY! b00k!!! † terminates the usefulness of the encryption program. Reason being that one can no longer be able to decrypt information/data that he/she encrypted earlier. References Whitten, A. (1999). Why Johnny Can’t encrypt: A Usability Evaluation of PGP 5. 0.

Cellular Reproduction :: science

Cellular Reproduction Cellular Reproduction is the process by which all living things produce new organisms similar or identical to themselves. This has to happen because if a species were not able to reproduce, that species would quickly become extinct. Reproduction consists of a basic pattern: the conversion by a parent organism of raw materials into offspring or cells that will later develop into offspring. The reproductive process, whether asexual or sexual always involves an exchange in hereditary material from the parents so that the new organism may also be able to reproduce. Reproductive processes can be categorized into either asexual reproduction or sexual reproduction. Asexual reproduction is any form of reproduction that does not require the union of male and female reproductive material (sperm or egg). Most single celled organisms reproduce by the asexual process known as fission, which is commonly called mitosis. Fission is The splitting of a nucleus into two roughly equal parts accompanied by the release of a pretty large amount of energy. Interphase, the first phase of the cell cycle and also the phase before mitosis, starts as soon as the cell is born. Interphase is broken up into three phases, G1, S, and G2. During the G1 phase, the cell increases in mass except for the chromosomes, which stay the same. Protein synthesis is also occurring during this phase. If a cell doesn't divide further, it remains in the G1 phase. Next is the S phase, in which the mass of the cell continues to increase, and DNA is duplicated, and then the chromosomes divide. During the G2 phase of Interphase, the cell becomes double its mass at birth, the chromosomes beg in to shorten and coil, and the centrioles appear, the cell is now ready to enter into mitosis. In the first phase of mitosis, prophase, the chromosomes become visible and the centrioles split in half and then move to opposite sides of the cell. At this point chromosomes have formed into two chromatids separated by a structure called a centromere. Spindle fibers are barely visible. During metaphase, the second phase of mitosis, the two chromatids line up along the equator of the cell. Each chromatid has its own spindle fiber. Next comes the third phase of mitosis, Anaphase, in which the centromeres break in half, causing each of the two chromatids to start to be pulled to different sides of the cell.
