📚 加密数据的方法有很多种,其中最基础的是凯撒密码算法(Caesar Cipher Algorithm), 请写一个程序完成此算法。加密方法满足下列关系式: 💭 比如:key为2,P为"ABCDE"时 ,则C为"CDEFG" (Plain text 为加密前的内容,Cipher text 为加密后的内容) 📌 要求: ① 限制要加密的内容长度为30以下,以 储存。 ②...
The Caesar cipher is an ancient encryption algorithm used by Julius Caesar. It encrypts letters by shifting them over by a certain number of places in the alphabet. We call the length of shift the key. For example, if the key is 3, then A becomes D, B becomes E, C becomes F, and...

What is a Caesar Cipher ?The Caesar Cipher algorithm is the simple and easy approach of encryption technique. It is a simple type of substitution cipher in which the alphabets are moved by using a selected number of areas to create the encoded message. An A can be encoded as a C, M ...

Caesar Cipher Programming Algorithm in C++. In cryptography, a Caesar cipher, also known as shift cipher, Caesar's cipher, Caesar's code or Caesar shift, is one of the simplest and most widely known encryption techniques. It is a type of substitution cip
The algorithm is simple; for example, if we perform encryption on the text delftstack, the Caesar Cipher algorithm will encrypt the text by replacing the characters with the fixed position below the characters in alphabetic order.We pass a key which is an integer, to decide how many positions...
