[CA认证] There-are-three-types-of-cryptography-techniques.
说明：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<pradeep> 在 2025-06-06 上传 | 大小：65kb | 下载：0

[CA认证] diffeehellmanPROGRAM
说明：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<pradeep> 在 2025-06-06 上传 | 大小：28kb | 下载：0

[CA认证] transposition
说明：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<pradeep> 在 2025-06-06 上传 | 大小：39kb | 下载：0
