What is symmetric or secret key encryption ?

-

" Symmetric key encryption is a type of encryption, also called secret key encryption. It uses a private key or secret key to encrypt a message, and also decrypt with the same key, so called secret or private key encryption."

Symmetric key encryption is a kind of encryption which uses AES algorithm to encrypt a message. Symmetric key encryption uses a secret key and AES algorithm to encrypt a message and also decrypt when same key is used to decrypt it. Symmetric key encryption is faster than Asymmetric key encryption.
The only problem with this encryption technique is, multiple keys are generated to distribute among people. So the management of keys and hazards of losing key secrecy are two common issues in this encryption technique.

Symmetric key encryption is used by software companies to secure their products, password protected zip and PDF files and so forth.



So we have learned now, What is Symmetric or secret key encryption ? And what are the various methods used for decryption, keep learning from computerflicks. Please leave comments.

What is BSQL or Blind SQL Injection?

-
"BSQL is an acronym of Blind SQL Injection , a sort of SQL Injection, used when a customized error page is sets as a substitute of database error message in order to increase database complexity for intruders." Blind SQL Injection or BSQL is a kind of SQL Injection , which is used to find out vulnerabilities in a database system to exploit. Blind SQL is similar to SQL Injection because in both ways an intruder try to steal digital identities or data from a database system in order to exploitation. To Increase the SQL Injection complexity a developer or application programmer sets an error page as a substitute of database error message. So when a hacker apply SQL Injection attack on a database system a customized error page is returned except database error message, which makes that intruder or hacker blind to exploit with database. Eventually, this problem for hackers raise to create a new kind of SQL Injection to attack blindly on the...
