Security in a transaction activity is crucial, in digital communication that irresponsible parties can tap all objects sent in the form of bits, the use of cryptographic algorithms such as Base64 and Word Auto Key Encryption can be a solution that produces a secure ciphertext, base64 algorithm which can encode all objects such as text, image, and audio files into text form and the result is re-secured with Word Auto Key Encryption algorithm, the results of this research get better security by combining the two algorithms. © Published under licence by IOP Publishing Ltd.
