Resources for Hermetic Systems [1 - 15 of 20]
-
A program for secure file deletion and disk wipe which destroys (or purges, by overwriting) data in files on floppy, ZIP or hard disk so that the data cannot be recovered. A single file can be purged or, in batch mode, multiple files (in multiple folders) can be purged in one operation. Allows user-specifiable type of purge. Purge speed can be tested for accurate estimation of purge times. -
This program is six tools in one. It creates a new HTML document template, automates most of the tasks involved in converting a text file (which may consist of program code) to a decent-looking HTML document, converts data in a text file to an HTML list or table, and creates the HTML code for tables, with the possibility of specifying cells larger than 1 row by 1 column and of entering text into the table cells. -
Allows easy performance of date calculations. Adds a number of days to a date, calculates the number of days between two dates and converts among Gregorian dates, Julian dates, ISO Week dates, Hermetic Leap Week dates, Julian day numbers and ordinal dates. Weekends may be included or excluded. It has a built-in programming language, with control structures, variables and functions, which allows users to run their own date-processing programs. -
Designed for easy performance of date calculations. Adds or subtracts a number of days or months to a date, calculates the number of days between two dates and converts among Gregorian dates, Julian dates, ISO 8601 Week dates, Hermetic Leap Week dates, Julian day numbers and ordinal dates of the form yyyy-ddd. Weekend days may be included or excluded. Program is bilingual: English and German. -
Software for exploring five cellular automata: q-state Life (a generalization of Conway's Game of Life), the Belousov-Zhabotinsky Reaction, Togetherness, Viral Replication and Diffusion-Limited Aggregation. The documentation provides a complete description of the algorithms used. -
A program to search for eclipses (lunar, solar, total, annular and umbral), to calculate the phase of the Moon at any given date and time and to convert between dates in the Gregorian and Julian calendars and dates in four lunar calendars (Goddess Lunar, Meyer-Palmen Solilunar, Hermetic Lunar Week and Liberalia Triday). -
Hermetic Stego is a a steganography program which allows you to encrypt and hide a file of any size in one or more BMP image files, with or without the use of a stego/encryption key, so that the presence of the hidden file is undetectable , even by forensic software using statistical methods and if a user-specified stego key is used then the hidden file can be extracted only by someone, using this software, who knows that stego key. -
For converting between BMP, GIF, JPG and PNG graphics files. Has two modes of operation: (i) A single file can be converted to all other formats (except GIF) in one operation, and JPGs can be output over a range of quality (compression) values. (ii) In batch mode any number of files in a folder can be converted from one format to another (except GIF). Converted files can be displayed automatically in the default browser. -
This software is for indexing and searching an HTML file, a text file or a file of a similar kind on CD, hard disk, etc. It indexes every word in the file, and any word in a set of words, or an exact phrase, can be found by searching. Results are presented as extracts from the file and can be displayed in a textbox or in a web page in your browser. -
This software is for indexing and searching HTML files, text files or files of a similar kind on CD, a hard disk, etc. It indexes every word in every file, and any file containing a particular set of words (or any of those words, or an exact phrase) can be found by searching for those words. It consists of two modules: An index module used to create an index of the searchable files, and a search module used to search those files. -
The Prime Number Spiral (a.k.a. the Ulam Spiral) is formed by marking the prime numbers in a spiral arrangement of the natural numbers. This is software is for exploring the Prime Number Spiral. -
This software scans a file, or text on the clipboard, and counts the number of occurrences of the different words. The text can be in a language other than English and can be a program code. The words which are found and displayed can be ordered alphabetically or by frequency. There is no limit on the size of an input file. The manner in which words are counted can be customized. Can be used with XML files. Results can be written to a file. -
This program is for backing up sets of files on a regular basis. It can be told to back up only files which have been modified, and new files, since the last backup. It will report on which files are new, and which modified, since the last backup. It also maintains congruency between the current files and the backup files by allowing deletion of obsolete backup files and folders. -
Cryptosystem ME6 is a Windows program which uses a symmetric key encryption system to encrypt information in either a single file or in multiple files (at once) so that it cannot be read by those not knowing the key. Data is encrypted using a key which is from 16 to 64 characters long, and which can be either a phrase or a sequence of 64 random bytes (the software provides a way for you to generate such random keys). -
Factorizer may be used: (1) to get the prime decomposition of all numbers in a range of numbers, (2) to get all factors of a single number or all factors of all numbers in a range, (3) to find only the prime numbers in a range of numbers, (4) to find pairs of prime numbers in a certain range, (5) to count (without displaying) the prime numbers in a range of numbers and (6) to find Fermat and Mersenne primes less than 2,147,483,647.
