AbstractThere are three basic encryption methods: hashing, symmetric cryptography, and asymmetric cryptography. Each of these encryption methods have their own uses, advantages, and disadvantages. All three of these encryption methods use cryptography, or the science of scrambling data . Although there can be several pieces to an encryption process, the two main pieces are the algorithms and the keys. As stated earlier, algorithms used in computer systems are complex mathematical formulas that dictate the rules of how the plaintext will be turned into ciphertext. A key is a string of random bits that will be used by the algorithm.
This paper proposed a method which generates the key that draw from parts of the image. The size of the key is used with the suggested algorithm to encryption of the text. This method could be applied to Symmetric cryptography or Asymmetric cryptography.
