Encryption is essential for protecting data, with both symmetric and asymmetric methods offering unique advantages.

In this paper, the authors used the stream cipher which is the best way with the algorithm Geffe generator with a specific length to encryption the information from plain text in the first compute.

In this paper, the authors provide with an encryption decryption algorithm with secure strength, bringing failure to the intruder effort to break the cipher.

In the real world, public-key encryption is practically never used to encrypt actual messages. The reason is that it requires so much computation—even on computers, public-key is very slow.

Cryptography is the art of keeping information secret and safe by transforming it into form that unintended recipients cannot understand. It makes secure data transmission over the internet possible.

The process of making text secret is called encryption, and the reverse process is called decryption. Ciphers have been used long before computers showed up.

The Cipher object uses the same methods to encrypt and decrypt data, so you must initialize it first to let it know what you want done with the data: cipher.init (Cipher.ENCRYPT_MODE, key); ...
