https://www.maplesoft.com/applications/view.aspx?SID=153920&ref=Feed
In the cryptographic research an important operation is to determine the byte-frequency of non-encrypted and encrypted files. This action allows us to appraise the quality of the cryptographic algorithms. This application implements a `byte-frequency analyzer` in Maple. Results are displayed in column graphs, using both linear and logarithmic scales on the y-axis. The logarithmic y-axis is very useful if the differences between the byte values are large. The displayed column graphs can be exported in six formats (Bitmap, PNG, GIF, JPEG, Encapsulated Postcript, PDF and Windows Metafile) for use in documents concerning cryptography and file processing tools.<img src="https://www.maplesoft.com/view.aspx?si=153920/bytefreq.png" alt="Byte Frequency Analyzer" style="max-width: 25%;" align="left"/>In the cryptographic research an important operation is to determine the byte-frequency of non-encrypted and encrypted files.

An easy-to-use interactive Maple implementation of transport encryption scheme has been presented. It allows to encrypt any file with arbitrary extension stored in the used computer system and in portable memory devices. The encrypted file may contain all 7-bit characters. Therefore, the encrypted file can be securely transmitted over the internet as an e-mail enclosure. The application encrypts also the name of the plaintext file: this way, the kind of content of the plaintext file is hidden. The encrypted file is saved in the same folder as the plaintext file. On encryption/decryption in the GUI Text Area the user will see an exhaustive information about the performed task. On decryption, the encrypted file is removed. The presented applications sm128b.mw must have permission to save and remove the processed files. It is worth to know that the secret key in the application is embedded.

https://www.maplesoft.com/applications/view.aspx?SID=153841&ref=Feed
An easy-to-use Maple implementation of transport encryption has been presented. It allows encrypting any file with arbitrary extension stored in the used computer system. The encrypted file contains space, alphabetic and decimal digit characters and the following special characters !#$%&'()*+,-./:;<=>?@[]^_`{|}~. These 93 printable characters can be defined by the set {32, 33, 35, seq(i, i=36 .. 91), seq(i, i=93 .. 126)} of byte values. Therefore, the encrypted file can be not only securely transmitted over the internet as an e-mail enclosure, but also protected effectively against unauthorized access. The application encrypts the name of the plaintext file as well: this way, the kind of content of the plaintext file is hidden. The encrypted file is saved in the same folder as the plaintext file. The size of the encrypted file is about 22.3% greater than the size of the plaintext file. On encryption/decryption in the GUI Text Area the user will see exhaustive information about the performed task. On decryption, the encrypted file is removed. It is worth knowing that the secret key in the application is embedded. Thus, any user can install his own secret key in the application in many ways. For example, he can change the value of the variable skc and the value of the variable seed in the procedures fne and fnd. The presented applications fed479k.mw must have permission to save and to remove the processed files.

In the `RFC 4648` document (http://www.rfc-base.org/rfc-4648.html) the commonly used base 64, base 32, and base 16 encoding schemes are decribed. The output file, encoded according to this document, is about 33%, 60% and 100% greater than the input file, respectively. The presented application uses the base value equal to 93, and now the encoded file is only about 22% greater than the input file. The application must have a permission to save and to remove the files processed. It is easy to use - the reader is informed which tasks are being performed for any selected option, namely, he will know the input file size and name, the output file size and name, the encoding/decoding rates.In the `RFC 4648` document (http://www.rfc-base.org/rfc-4648.html) the commonly used base 64, base 32, and base 16 encoding schemes are decribed.

L. G. Pardo - Introduction to Cryptography with Maple). On unpacking the file `elgmail.zip` the user will see three public key files: `ElGpub_Eve_Flower.m`, `ElGpub_Jack_Herod.m`, `ElGpub_Michele_Lazy.m` and three application worksheets: `ElGedm_Flower.mw`, `ElGedm_Herod.mw`, `ElGedm_Lazy.mw` in which the proper private keys are embedded. Each of the three users can encrypt an e-mail letter and can send the encrypted message to the required addressee, knowing its public key. Evidently, any user can also decrypt the proper encrypted message, addressed to him. The way of generating the public and private keys demonstrates the worksheet ElGkg.mw. The data contained in the names of the computed keys using the worksheet ElGkg.mw is evident. In the presented example the e-mail message should contain no more than 782 printable characters with byte values less than 127. The scheme can be accepted for any e-mail system: the public keys and encrypted messages are Maple `*.m` format files containing characters with 91 byte values from the set {10, 33 .. 122}. The user can also observe the time needed for encryption, decryption and the computation of keys, and the encryption scheme redundancy.

It has been shown a new approach to Maple programming allowing to create so-called OM applications (OM means One-Maplet). The approach consists inusing Base64 encoding scheme for embedding files of any format in the source codeof the maplet. In the presented "Entertainment" OM application one *.jpg file and five *.exe files are embedded. For Windows only
