Penerapan Kombinasi Sandi Caesar dan Vigenere untuk Pengamanan Data Pesan pada Surat Elektronik

Abstract

Security of the content of the message is especially important if the message sent by internet or email access. The security techniques may use a combination of algorithms Vigenere cipher and password. Both are part of the science of cryptography. It would be easier if the algorithm is implemented into an application that can later be used to secure the contents of the email message so that the message is protected from acts of interception.
