Is encryption effective

[Doroteo]

Hi,
Due to vast use of online activities data had no more remain private. I was just wondering that does encryption is enough powerful today to handle confidential information. Does it gives out a balanced service and it is safe to rely on different types of encryption tools and services. The best examples for this Digital Signature. I saves my important documents and send them only after authentication. What are your views on it. Thanks.

Encryption is the act of transforming a text readable in a text unreadable via an encryption key. Only a person with the decryption key (which may be the same as encryption) will be able to decipher the text. A cipher is said to be balanced if the key encryption and decryption are the same. Symmetric encryption is also called secret-key encryption ", since this key should be known that people ought to have the right to encrypt / decrypt the message.

Encryption are off different types the most secure is Asymmetric encryption is also called public key encryption. Indeed, if a person wants his correspondents sends encrypted messages, it will then generate 2 keys. A first key used to encrypt messages, which will be sent to correspondents, so that they use to encrypt their messages. A second key used for decrypting it at, and which should remain private so that only the person issuing the keys to decrypt messages.

An encryption system is never completely secure. It must even be assumed that whatever the algorithm used, find a loophole or a way to decrypt the protected data is a matter of time. According to the key size (measured in bits), it is a finite number of combination that a hacker can try to try to decipher the message. For example, if information is supposed to remain secret a month and is protected by an encryption system that can withstand 5 years, it is clear that you can sleep in peace, the security of your message is theoretically guaranteed.
