The number of techniques are used for speech encryption. However in our approach the work is done on different kind of techniques i.e. MD-5 , SHA-2 and Rinjdael these three popular techniques are used for text encryption. In this work of thesis the speech is first converted into text ...
Now that we’ve figured out the encryption for plain text capital letters using Ceaser Cipher let’s look at how we will decrypt the ciphertext into plain text. Earlier, we looked at the mathematic formulation of the encryption process. Let’s now check out the same for the decryption proce...

密码学Cryptography | 密码学(Cryptography)这一话题(向潜在敌人隐藏信息)已经存在了数千年。随着现代技术、计算机和电信的出现,它发生了巨大的变化。加密(encryption)是一种获取消息(称为明文 plaintext)并对其实施某个应用操作(称为密码或暗号 cipher)的行为。因此,在收到一条乱码、不可读的消息作为输出时,我们称为...
It gets a bit more specific in cryptography, where plaintext refers to a message before it’s encrypted that’s visible to everyone besides the intended recipient or sender. During encryption, an algorithm is used to scramble the content of the message and turn it into an unintelligible string...
An encryption algorithm. A message after it has been encrypted. cryptography The science of keeping information secure. factor Any number that divides a given integer. factoring Reducing an integer into its prime factors. hash The output of ahash function. ...
The DNA-Crypt algorithm and image steganography are based on the same watermark-hiding principle, namely using the least significant base in case of DNA-Crypt and the least significant bit in case of the image steganography. It can be combined with binary encryption algorithms like AES, RSA or...
If you plan on using reversible encryption, always use a strong encryption algorithm such asDES,Blowfish, or some other algorithm that has been proven secure. Never use XOR, ROT-13, or a homegrownencryption code; these usually provide little protection and are easier to break than people realiz...
