client enc - server dec

This project shows how to encrypt a data in client using public key;
and send it over to server and decrypt it using “private key” in scala.

example:
send a encrypted data to server to get decrypted.

https://en.wikipedia.org/wiki/Padding_(cryptography)

  1. Official messages often start and end in predictable ways:
  3. My dear ambassador, 
  4.     Weather report, 
  5. Sincerely yours, etc. 
  7. The primary use of padding with classical ciphers is to prevent the cryptanalyst 
  8. from using that predictability to find known plaintext that aids in breaking the encryption. 
  10. Random length padding also prevents an attacker from knowing the exact length of the plaintext message.

https://en.wikipedia.org/wiki/Optimal_asymmetric_encryption_padding

  1. a padding scheme often used together with RSA encryption.
