Text Encryption And Decryption Project In Java

• Java Encryption Example

In this Java tutorial we will see about what PBE is and how we can use it in Java to encrypt and decrypt a file. In Password based encryption (PBE), a password is chosen and it is used along with a generated salt (key) to encrypt. Then the same password is used along with the salt again to decrypt the file.We have following 3 steps to achieve password encryption and decryption. Generate Random Key.

Generate Encrypted Password from plain text password. Retrieve plain text password from Encrypted passwordGenerate Random Key.

Java Encryption Example

Here you will get program for caesar cipher in Java for encryption and decryption.Caesar Cipher is an encryption algorithm in which each alphabet present in plain text is replaced by alphabet some fixed number of positions down to it. Take below example.Plain Text: ABCDKey: 3Cipher Text (Encrypted Message): DEFGAs key is 3 so each alphabet will be replaced by an alphabet 3 places down to it.To decrypt a cipher text, the reverse of encryption process is followed.Also Read:Also Read:Below I have shared the program to implement this algorithm in Java.
