In the digital era, data transmission is mostly done by using internet media such as sending via email and social media. In sending information using the internet there are many threats that can occur such as corruption, tapping, modification, and fabrication. In securing information there are several ways including using data disguise techniques called cryptography. The Trifid Cipher algorithm uses polybial cubes to convert letters to numbers and write numbers vertically under the message with sequences, columns, and rows. Then the numbers are read horizontally and then grouped into 3 parts then the cube is used again to convert numbers to ciphertexts.
