Message security in communication is very important to maintain the confidentiality and integrity of messages. The message that is sent must be conveyed in its entirety and only delivered according to its purpose. One Time Pad or OTP is an algorithm that can encrypt messages into ciphertext so that message security can be guaranteed. OTP is a symmetric cryptographic algorithm, that is, the key for encryption and decryption is the same. To perform encryption, the OTP plaintext length must be the same as the key length. This will make it difficult when there is a very long length of plaintext, so the key must also adjust it. OTP keys also have a weakness if a key has been used more than once. Therefore a key builder is needed. In this research, the key generator used is base64. Base64 is used to change the bits of plaintext that will be used by OTP. In this study, base64 can encode plaintext to be used as an OTP key so that it succeeded in making the key generator from base64 encoding.

PT. Tanabe Indonesia is engaged in manufacturing in the health sector and uses cloud-based email and folder sharing facilities. In this case the company does not have a security system that can secure the contents of e-mail messages. In its implementation, the process of sending email on a network does not rule out being read by irresponsible people, such as intruders. This problem can be solved by creating an Email Data Security Application Using a web-based XTEA (Xtended Tiny Encryption Algorithm) Cryptographic Algorithm, so that email messages are not easily compromised. The application that is built also has additional facilities, namely the login process to be able to access it, so that only certain parties who have access rights can use this application. The programming language used in building this data security application is the web-based PHP programming language. From the test results, the file format will change to .sc format. and after going through the encrypt process it will change to be bigger with the average file size increasing by about 22.221 percent from the original file size before going through the encrypt process. From the test results after going through the decrypt process the average file size change will increase by 77.779% percent (22.221 percent reduction), which is the same as the average in the encrypt process.

The internet network is growing rapidly and has a great impact on human life. The development of the internet network has enabled many people to exchange information or messages,one of tham by using email media. Apparently the internet is a path that in ni not too safe because it is a common communication media that can be used by everyone so prone to tapping information or messages. Therefore, security and confidentiality are needed in data communications. One may to keep messages safe is to use steganography technique. The steganography method used is the method of message insertion using BPCS (Bit Plane Complexity Segmentation). Before the message is inserted, the message is first encrypted using cryptography techniques. The cryptographic algorithm used is RSA algorithm. RSA algorithm consists of encryption algorithm and decryption algorithm. The confidential message is encrypted using RSA encryption algorithm and inserted using the insertion method of BPCS. With the technique of steganography on the image media then the delivery of a secret message will have a good level of security because it can not be detected directly by the senses of human vision. Keywords: cryptography, steganography, RSA, method BPCS Abstrak Jaringan internet berkembang dengan pesat dan memberikan pengaruh besar bagi kehidupan manusia. Perkembangan jaringan Internet telah memungkinkan banyak orang untuk saling bertukar informasi atau pesan salah satunya dengan media email. Ternyata, internet merupakan jalur yang tidak terlalu aman karna merupakan media komunikasi umum yang dapat digunakan semua orang sehingga rawan penyadapan informasi atau pesan. Oleh karena itu, keamanan dan kerahasiaan sangat dibutuhkan dalam komunikasi data. Salah satu cara untuk menjaga keamanan pesan adalah menggunakan teknik steganografi. Metode steganografi yang digunakan adalah metode penyisipan pesan, dengan menggunakan metode BPCS (Bit Plane Complexity Segmentation). Sebelum pesan disisipkan terlebih dahulu pesan tersebut dienkripsi dengan menggunakan teknik kriptografi. Algoritma kriptografi yang digunakan adalah algoritma RSA. Algoritma RSA terdiri dari algoritma enkripsi dan algoritma dekripsi. Pesan rahasia disandikan menggunakan algoritma enkripsi RSA dan disisipkan menggunakan metode penyisipan BPCS. Dengan adanya teknik steganografi pada media citra maka pengiriman suatu pesan yang bersifat rahasia akan memiliki tingkat keamanan yang baik karena tidak dapat dideteksi langsung oleh indera penglihatan manusia.
