HS SMTP Lite
By Hillstone Software
HS SMTP LITE is a software library in C (supplied with full source code) which implements the client side of Simple Mail Transfer Protocol (SMTP) over TCP socket layer according to RFC 821. Support for transfer of basic message header and text is provided To send a text email message to any address on the internet, the user application calls a single function HsSmtpSendMail, specifying mail server name or IP address, sender address, recipient address, message text buffer and length, subject, cc and an event callback function to use for reporting of operation result and server errors. HS SMTP library then resolves the server name, connects to it and transmits the message according to SMTP RFC 821 protocol. HS SMTP Library incorporates the necessary state machine, transparency procedures, and server response processing required to comply to a simple and robust SMTP client implementation. Modular design makes it easy to port HS SMTP protocol module to any environment. HS SMTP internally at a lower layer interfaces to HS Sock library which provides TCP transport services. User application need not worry about Winsock - HS SMTP does all transmission, reception and event handling over socket layer. Features -SMTP Client Operation -Server name resolution -Supports up to 5 contexts -Message Header Transfer -Message Text Transfer -Asynchonous Operation Customization: Hillstone Software provides additional services for customization, porting and integration of the library code to better suit the needs of your products API summary -HsSmtpInit -HsSmtpDestroy -HsSmtpTick -HsSmptSendMail -HsSmptAbortMail

HS Compress C Source Library
By Hillstone Software
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.

HS Crypto C Source Library
By Hillstone Software
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. Once the purchase is made you will receive download link by email to download full product deliverables, which include: - HS Crypto library binaries. (Win32 static library) - HS Crypto library full source code in C with MS Visual C project workspace - HS Crypto Demo Application binaries, full source code and MS Visual C project workspace. - HS Crypto library user manual, which documents in detail complete library API.
HS FTP Client C Source Library
By Hillstone Software
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.
