ABSTRACT
The text format is a character format that can be read directly with any software. This format is used in sending data to facilitate sending and speed up sending data to message recipients. The text format is the message storage format with he least security because it can be directly read by the person who gets the message. The author wants to build a cryptographic application that can secure text formats using the character transposition technique. Character transposition is used based on the formation of a square matrix which is used as a key in the encryption and decryption process. The size of the matrix used is 4 x 4. The results of the study found that the text format was successfully transformed into ciphertext so as to avoid the possibility of data theft.
