Hi, }, /* Thanks for sharing, saved me some time. example i have: aa=dr; ab=fh; ac=er;… and all any combinations with two letters (676) Bro why it give me wrong result of encryption and decryption, can you find the mistake. The Caesar Cipher technique is too simple I guess and therefore, it becomes easier to program as well. Ideally, we want to account for larger keys that are greater than 26 (hence using %). ch = ch – key; if(ch < 'A'){ Julius Caesar protected his confidential information from his enemies by encrypting it. cs50 pset2 caesar solution. "\n1. for(j=0;jz ?to encrypt in only alphabets?if so can u explain the logic..? Caesar cipher encryption. Enter key: 2 Decrypted message: yx EhI. } This encryption technique is used to encrypt plain text, so only the person you want can read it. Enter a message to encrypt: axzd While Caesar's was the first recorded use of this scheme, other substitution ciphers are known to have been used earlier. CHECK THIS OUT A Caesar cipher is a trivial method to obfuscate text by substituting each character with it successor (or nth successor).
