Encryption and Decryption of Data using AES algorithm with example code ~ Code 2 Learn. There are many problems when you try encrypting a string such password, credit card nos, phone no. After spending sometime on this i finally got the best algorithm that a person can use to encrypt and decrypt data while he/she also wants to store those encrypted strings and later on want to decrypt it while retrieving the data. Many people face problem while decrypting the encrypted data as the KEY used for encryption if stored as String in database then it becomes very tough to use that string as the KEY.
The above code is still really basic its not the best we can do with AES. This is the snippet Rijndael AES Block Encryption Demo (VB/ASP) on FreeVBCode. The FreeVBCode site provides free Visual Basic code, examples, snippets, and articles on a variety of other topics as well. So below is the code where you only need to store the encrypted code and not the key. The decryption will take place as an when wanted. For encryption we must use a secret key along with an algorithm. In the following example we use an algorithm called AES 1. AES algorithm can use a key of 1. Invalid. Key. Spec. Exception; import javax. AESencrp . Error like : So to avoid this do the following : * Go to Window- -> Preferences- -> Java- -> Compiler- -> Error/Warnings.* Select Deprecated and Restricted API. Change it to warning.* Change forbidden and Discouraged Reference and change it to warning. As a leading provider of Media Oriented Systems Transport (MOST
