HS Crypto C Source Library 1.0

Submitted By: hillstone
Rating: Not rated (Rate It)

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
