It is computationally impossible for one-way hash functions to obtain the original data again. In this study, Two Way Hash Function (TWHF) is proposed which provides the security properties of one-way hash functions. TWHF aims to hash/encrypt and decrypt input data of arbitrary length. This allows data to be encrypted or decrypted regardless of its size. The proposed method uses "iteration-key" and secondary key to ensure confidentiality. In the study, strong hints were obtained that TWHF fulfils the security properties of one-way hash functions. TWHF stores the original data as small bit sets in a generated decimal number pattern. The last decimal number of the generated decimal number pattern is the hash code and the encrypted data. The contribution of the work is to propose an original data change function, data/block classification and workflow, and a functional method that has not yet been studied in the literature. The results show that the hashing/encryption process works consistently and that on average 99.83% of the data is decrypted smoothly in the decryption process.INDEX TERMS Cryptography, cryptology, hash functions, one way hash functions, two way hash functions.

“…Cryptography is a branch of cryptology that deals with designing algorithms for encryption and decryption to ensure the confidentiality and/or authenticity of messages. In 1991, the DSA was proposed by the U.S. [3]. The growing use of services like e-commerce and open network communications has highlighted the crucial role of public key cryptosystems as security solutions [4].…”

“…DSA uses Public key to verify the sender's message, but verifying is complicated compared to RSA.DSA set of rules works on three steps like,  Key generation  Signing  Verification Fig. 3 shows how the Encryption of message sign is executed; the message sign is sent through Hash characteristic to generate a hash code [3]. Then the hash code and random variety 'okay' is given as an input for signature algorithm in conjunction with worldwide public key and sender's private key.…”

Security is one of the most important issues in layout of a Digital System. Communication these days is digital. Consequently, utmost care must be taken to secure the information. This paper specializes in techniques used to defend the facts from thefts and hacks the use of quit-to-cease encryption and decryption. Cryptography is the important thing technique related to Encrypting and Decrypting messages. We use Digital Signature preferred (DSS) and the Digital Signature Algorithm (DSA). The code for this algorithm is written in MATLAB. The DSA Algorithm is commonly used in cryptographic applications to provide services such as entity authentication, key transit, and key agreement in an authenticated environment. This structure is related with steady Hash Function and cryptographic set of rules the government groups in USA as it is taken into consideration to be one of the safest approaches of protection system. This fashion-able could have a top notch effect on all of the Government Agencies and Banks for protective the facts.

“…Algoritma MD5 ditujukan untuk aplikasi tanda tangan digital, di mana sebelum dienkripsi dengan kunci privat di bawah cryptosystem publickey seperti RSA, file besar harus dikompresi dengan cara yang aman. MD5 adalah fungsi hash paling populer yang menghasilkan 128-nilai hash bit atau 16 karakter [10]. MD5 umumnya digunakan untuk memeriksa integritas file.…”

Salah satu teknik yang populer untuk mengamankan data dengan tingkat keamanan yang tinggi yaitu kriptografi. Berbagai penelitian telah dilakukan dengan menggabungkan kunci simteris dan kunci asimteris untuk mendapatkan keamanan ganda. Dalam makalah ini, tanda tangan digital diterapkan melalui Rivest Shamir Adleman (RSA) sebagai algoritma kunci asimteris yang akan digabung dengan algoritma kunci simteris Vigenere Cipher. RSA yang tahan terhadap serangan karena menggunakan proses eksponensial dan kuadrat besar dapat menutupi kelemahan Vigenere Cipher, sedangkan Vigenere Cipher dapat mencegah kemunculan huruf yang sama dalam cipher yang mempunyai pola tertentu. Vigenere cipher mudah diimplementasikan dan menggunakan operasi substitusi. Untuk mengkompresi nilai numerik yang dihasilkan secara acak, digunakan fungsi hash yaitu Message Digest 5 (MD5). percobaan dalam makalah ini telah memberikan kontribusi dalam peningkatan kualitas enkripsi dimana citra digital dioperasikan dengan MD5 yang kemudian hasilnya akan diubah menjadi RSA. Fungsi hash awal yaitu 32 karakter diubah menjadi 16 karakter yang akan menjadi inputan untuk proses RSA dan Vigenere Cipher. Pada citra berwarna yang digunakan sebagai media operasi, akan dilakukan pengecekan apakah citra tersebut sudah melalui proses digital signature
