CryptEnCrypt is a powerful software application designed for electronic data protection. The files on your hard disk have no protection from unauthorized access. That means anyone who has access to your computer will be able to open these files and read the contents. CryptEnCrypt allows you converting your existing files to encrypted files. Encrypted files contain just the same data as before, however the encrypted data is unreadable until it is decrypted, i.e. converted to the original state. CryptEnCrypt bases data encryption on a password that you specify while encryption process. Note that there are no backdoors in this software, if you forget your password then you will not be able to decrypt data and information will be unrecoverable. CryptEnCrypt allows you to choose several encryption algorithms to protect your data. These are AES, Triple-DES, GOST, RC2, RC4 and Data Protection API based algorithms. Strong encryption ensures that your information would not be easily stolen from your computer by hackers, government, or global surveillance networks.

HS Crypto C Source Library
$0 - 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.
