Abstract

Cryptography is a message hiding technique where the message can only be known by
the sender and receiver of a message, where the message is often called encryption. At this time
encryption has been developed, one of which is the Rivest Shamir Adleman (RSA) method which
uses two keys, public key and private key, where the key can be set with a prime number
calculation as the key generator for values of e, d, and n. Where the prime value calculation will
be the length of the characters from sending a message and the bit length of the key formation, it
is more difficult to solve because it is difficult to factor two very large numbers and it is considered
safe even though it has never been proven to be safe or not, therefore in this study will be security
is made even better by making a value for the value of e, p and q at random. In the process of
cryptographic processing of the RSA method, it uses visual basic for application (VBA) which has
been facilitated by Microsoft Excel, which is considered easier to implement and is considered to
be a computer user who certainly has Microsoft Excel facilities.
