Abstract :
Virtual credit card is virtual forms of credit cards for online transaction
in cyberspace. Virtual credit card has the same data as credit cards in general, they are data card numbers, expiration dates, and security codes. Virtual credit
card can be used to transact by others who knows the three data. Cryptography
was made using the Borizqy Secure Encryption (BOSE) algorithm which
implements the Huf man algorithm to encrypt virtual credit card data using a
private-key that is only known to the owner of the virtual credit card. Cryptography allows virtual credit card data to be stored in an encrypted form, then the owner of the virtual credit card decrypts encrypted data using a private- key that is predetermined when encrypting data
