Cryptography is a method used to protect the confidentiality of data. In super encryption, two or more encryption algorithms are combined to make it more secure. In this work Vigenere Cipher and Myszkowsi Transposition are combined to form a super encryption. Vigenere cipher is a technique of encoding messages with Caesar cipher using the characters in the key used. The key used in this algorithm is a symmetric key and the characters in the key will be used repeatedly if all the characters in the message have not been processed while the Myszkowski Transposition is a type of cipher transposition algorithm that has its own uniqueness The specialty of this algorithm is that it has the need for keywords with identically numbered repeated letters. The key used in this algorithm is in the form of words or letters that are converted into a sequence of numbers. The alphabetical arrangement of the letters in the keyword determines the numbers. The first letter in the alphabetical order will be the number 1, the second letter in the alphabetical order will be 2, and so on. The super encryption is expected to be both easy-to-implement and more secure. The data integrity is still guaranteed because the two algorithms work together to secure the data and enable its return to plaintext.
