 Use Caesar cipher to encrypt this message “Our meeting on Monday at building BB in the morning”  Use Caesar cipher to decrypt this message “ZH ZLOO WUDYHO EB WUDLQ LQ WKH HYHQLQJ”

 Use Monoalphabetic and Vigenère ciphers to encrypt this message “Transfer money to me”  Encrypt word “BY” using Vernam cipher and then decrypt it again  ASCII code of B=  ASCII code of Y=

 Encrypt this message using Playfair cipher “save yourself”  Decrypt this message by Caesar cipher WKH HADP RI FRPSXWHU VHFXULWB WRGDB LQ WKH DIWHUQRRQ
