HS GSM SMS C Source Library 1.3 HS GSM SMS is a C source library. It provides a PC based user application with access to a mobile phone's Short Message Service (SMS) function, according to ETSI standards: GSM 07.05 (ETS 300 585) (use of DTE for SMS), GSM 03.40 (SMS)
HS X.25 C Source Library 1.0 HS X.25 is a software library in C (supplied with full source code) which implements ITU-T recommendation X.25. (with included HsDL (Data Link) and HsSock (Winsock interface) for X.25 over IP applications (XOT))
Description: 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.
- Fixed File Encryption
- Security / authentification
- Use either of the the two pre-defined translation tables
- Use dynamically generated translation tables
- Use alternating translation tables
- Buffer mode or character mode
