There-are-three-types-of-cryptography-techniques.
- Caesar cipher is a simple substitution cipher where each letter in the plain text is replaced with a letter a fixed number of places down the aplhabet. EXAMPLE If the number of places to shift is 3, the letter A would be converted to ltter D. Usi
DES-Program
- DES was once a predominant symmetric-key algorithm for the encryption of electronic data. It was highly influential in the advancement of modern cryptography in the academic world.
diffeehellmanPROGRAM
- Example 1. To find 1537 x 4248 modulo 10, you could multiply out and take the last digit, but a better way would be to replace 1537 by 7 and 4248 by 8 to start, find 7 x 8 = 56, and then take 56 mod 10 to get 6 as the answer. A handy standard no

transposition
- In cryptography, a transposition cipher is a method of encryption by which the positions held by units of plaintext (which are commonly characters or groups of characters) are shifted according to a regular system, so that the ciphertext constitutes

winhexCn
- 好用的功能,实用且简单操作哟。大家共同分享。-very good s program
distribution
- Normal, Uniform, Triangular distribution. Their composition.
RSA
- RSA is one of the first practical public-key cryptosystems and is widely used for secure data transmission.
Vigenere-Ciphers
- The Vigenère cipher is a method of encrypting alphabetic text by using a series of different Caesar ciphers based on the letters of a keyword.
monoalpha
