Using Java Cryptography Extension(JCE) library, implement a Javaprogram that will do the following:

ï· Read the contents of a text file (plaintext.txt)

ï· Encrypt it using AES (you can use default mode and padding)

ï· Write the ciphertext to a text file (ciphertext.txt)ï· Read the content of ciphertext.txt
