Hillstone Software - Software Products

HS Crypto is a software library in C (supplied with full source code) which offers a programmer an API to several data encryption / decryption algorithms. Implemented methods include the use of 2 either pre-defined or dynamically generated translation tables, an XOR-based stream cipher method with random dynamic key, plus the library includes RFC1321 MD5 Message Digest Algorithm The table encryption is implemented via the use of two either pre-defined translation tables or any of the 2 or a combination of dynamically generated translation tables. Decryption is implemented in a similar way using reverse tables. The stream cipher method uses randomly generated key which must be known to both receiver and transmitter to encode each byte with a rotating byte of the key RFC1321 MD5 algorithm generates a 16 byte data signature which is unique to the input data. This may be used for data integrity checking or in digital signature applications. * Applications: - Fixed File Encryption - Telecommunications - Security / authentification *Supported MODES - Use either of the the two pre-defined translation tables - Use dynamically generated translation tables - Use alternating translation tables - Buffer mode or character mode *Summary of API Functions: - HsSetCryptMode - HsEncryptByte - HsDecryptByte - HsEncryptBuf - HsDecryptBuf - HsCryptGenerateXlat - HsCryptGetXlat - HsCryptSetXlat - HsMd5Buffer - HsMd5File The library currently costs EUR 49.00 for unlimited user license.

HS Compress C Source Library

HS Compress is a software library (supplied with full C source code) which provides a programmer with a lossless compression / decompression algorithm based on RLE (runtime length encoding) The library may be used in telecommunications application or for fixed data compression. *HOW IT WORKS: Runtime Length Encoding (RLE): HS Compress library operates in buffer mode. It monitors the buffer data for presence of any four or more consecutive repetitions of the same character. If detected, the compression code, character and length are stored in the output buffer. HOW TO BUY: You can purchase the library online using credit card payment at: http://www.hillstone-software.com/hs_compress_buy.htm The library currently costs EUR 29.00 for unlimited user license. Once the purchase is made you will receive download link by email to download full product deliverables, which include: - HS Compress library binaries. (Win32 static library) - HS Compress library full source code in C with MS Visual C project workspace - HS Compress Demo Application binaries, full source code and MS Visual C project workspace. - HS Compress library user manual, which documents in detail complete library API.

HS NMEA GPS C Source Library

HS GPS is a software library (with full C source code) which provides access to a NMEA-183 compliant GPS receiver via a serial communications port, decoding NMEA sentences: $GPGGA, $GPGSA, $GPGSV, $GPGLL, $GPRMC and $GPVTG. Decoded parameters include: time, date, position, altitude, speed, course and heading, according to standard - NMEA-183 (National Marine Electronics Association, Interface Standard 0183. * HOW IT WORKS: HS GPS library continuously reads asynchronous data stream from a serial port and analyses the information to recognize and decode NMEA-183 Protocol sentences. After each message is received it is checked for integrity by comparing the received and the calculated checksum. The NMEA sentence fields are then converted from ASCII values into C structure variables and passed up to user application code. * Applications - Navigation - Security - Telematics - Fleet Tracking - Asset Tracking - Any customer applications requiring access to a NMEA-183 compliant GPS receiver * Features - Interfaces a GPS receiver over COM ports COM1 - COM8 - Decodes most commonly used NMEA sentences from a GPS receiver: - GGA - Global Positioning System Fix Data - GLL - Geographic Position - GSA - DOP and Active Satellites - GSV - Satellites in View - RMC - Recommended Minimum Specific GNSS Data - VTG - Course over Ground and Ground Speed HOW TO BUY HS GPS LIBRARY: You can purchase the library online using credit card payment at: http://www.hillstone-software.com/hs_gps_buy.htm The library costs EUR 79.00 for unlimited user license. Once the purchase is made you will receive download link by email to download full product deliverables, which include: - HS GPS library binaries. (Win32 static library) - HS GPS library full source code in C with MS Visual C project workspace - HS GPS Demo Application binaries, full source code and MS Visual C project workspace. - HS GPS library user manual, which documents in detail complete library API

HS NTP C Source Library

HS NTP is a software library in C (supplied with full source code) which implements the client side of Network Time Protocol (NTP) over UDP socket layer according to RFC1769 and RFC1305. HS NTP Library allows a user application to synchronise local system time to remote NTP server time. First user application calls HS NTP initialisation function supplying pointers to callback functions in user code for timer management and for reporting NTP events to user. To obtain time difference between local system and remote NTP server, the user application calls HsNtpGetTime function, specifying NTP server name or IP address and source UDP port to use. HS NTP library then resolves the server name, formats and sends NTP time request packet according to RFC1305 and RFC1769 standard. Once HS NTP has received NTP time reply from NTP server it analyses the reply and reports the resulting time difference to user application via callback function. The parameters to this event callback contain the offset value in seconds necessary to apply to local clock in order to synchronize it to the time at remote NTP server. Modular design makes it easy to port HS NTP protocol module to any environment. HS NTP internally at a lower layer interfaces to HS Sock library which provides UDP transport services. User application need not worry about Winsock - HS NTP does all transmission, reception and event handling over socket layer.

HS FTP Client C Source Library

HS FTP is a software library in C (supplied with full source code) which implements the client side of the File Transfer Protocol over TCP socket layer according to RFC 959. The library allows a user application to connect to remote FTP servers, traverse server directory structure and send and receive files. The HS FTP protocol module supports passive mode data connections, user / password authentication and a number of commonly used FTP commands: USER, PASS, TYPE, PASV, LIST, CWD, RETR, STOR Features - FTP Client RFC 959 operation - Server name resolution - Concurrent FTP client sessions - Passive mode, firewall friendly - User / password authentication - Asynchronous Operation what is supplied after you purchase the product? - HS FTP Library binaries (Win32 library) - HS FTP full source code in C with Visual C workspace and project files - Binaries and full C source code of HS SOCK module used by HS FTP for Win32 TCP/IP socket layer communications - HS FTP Demo Application binaries, C source code, project workspace - HS FTP User Manual which documents in detail complete library API To connect to remote FTP server, the user application calls HsFtpCliConnect, supplying connection parameters, such as remote FTP server name or IP address, username and password for authentication etc and a pointer to callback function that the HS FTP module uses to communicate with the user code. When the control FTP connection is established and HS FTP has successfully passed user / password FTP account authentication phase, the user application is asynchronously notified via user event callback function with HS_FTPCLI_USR_EV_LOGGEDIN event. The user application can now request remote FTP server directory listing using HsFtpCliList function, change directory HsFtpCliChdir, transfer files with HsFtpCliSendFile and HsFtpCliGetFile.
