- 1. Encryption And Decryption Using AES By Ankita Singh Prachi Sangli Asmita Shinde
- 2. What is Encryption And Decryption ? Encryption is the process of translating plain text data (plaintext) into something that appears to be random and meaningless (ciphertext). Decryption is the process of converting ciphertext back to plaintext.
- 3. Why Use Encryption ? Encryption is important because it allows you to securely protect data that you don't want anyone else to have access to. 1
- 4. What is AES (Advanced Encryption Standard) ? ◈ It is a symmetric block cipher chosen by the U.S. government to protect classified information and is implemented in software and hardware throughout the world to encrypt sensitive data. ◈ It was intended to be easy to implement in hardware and software, as well as in restricted environments
- 5. Design Of AES ◈ AES comprises three block ciphers: AES-128, AES-192 and AES-256. ◈ Each cipher encrypts and decrypts data in blocks of 128 bits using cryptographic keys of 128-, 192- and 256-bits, respectively. ◈ Symmetric ciphers use the same key for encrypting and decrypting, so the sender and the receiver must both know and use the same secret key.
- 6. Design Of AES ◈ All key lengths are deemed sufficient to protect classified information up to the "Secret" level with "Top Secret" information requiring either 192- or 256-bit key lengths.
- 7. Encryption The Code In Our Project, Converts A Text File Into An Encrypted File Using Java Code And AES Algorithm Using AES For Encrypting And Decrypting Text Decryption Later, That Encrypted File Can be Taken To Any Receiving System And Decrypted To View The Original Intended Text Using The Java Code.
