pseudocode caesar cipher code example

Example 1: python caesar cipher

def caesar_encrypt():
    word = input('Enter the plain text: ')
    c = ''
    for i in word:
        if (i == ' '):
            c += ' '
        else:
            c += (chr(ord(i) + 3))
    return c

def caesar_decrypt():
    word = input('Enter the cipher text: ')
    c = ''
    for i in word:
        if (i == ' '):
            c += ' '
        else:
            c += (chr(ord(i) - 3))
    return c
  
plain = 'hello'
cipher = caesar_encrypt(plain)
decipher = caesar_decrypt(cipher)

Example 2: caesar cipher in python

def encrypt(text,s):
result = ""
   # transverse the plain text
   for i in range(len(text)):
      char = text[i]
      # Encrypt uppercase characters in plain text
      
      if (char.isupper()):
         result += chr((ord(char) + s-65) % 26 + 65)
      # Encrypt lowercase characters in plain text
      else:
         result += chr((ord(char) + s - 97) % 26 + 97)
      return result
#check the above function
text = "CEASER CIPHER DEMO"
s = 4

print "Plain Text : " + text
print "Shift pattern : " + str(s)
print "Cipher: " + encrypt(text,s)
