This is the EnScrypt(tm) Cryptography Package for Macintosh

 How are the Highwinds Cryptographic tools implemented?

As suites of "Osaxen" inside Scripting Additions. Osaxen are fast sub-routines that can be called by AppleScript (and other OSA languages) on MacOS systems. To use EnScrypt or FreeBees, put them inside the "Scripting Additions" folder which is inside your System Folder and/or Extensions folder (depending on your version of MacOS).

It is a set of scripting tools to do encryption, digital signatures, password authentication, and other cryptographic functions. Built as a "Scripting Addition", EnScrypt is an indispensable tool for software developers, script writers and anyone needing to provide encryption security on the Macintosh platform. Encryption is provided for EnScrypt by the "Blowfish." " Blowfish" is one of several very secure and well-known symmetric encryption algorithims. It is by all measures state-of-the-art "strong encryption." Discovering an encrypted text by anything other than brute force is thought to be impossible (by professional cryptographers. References, "white papers" and sourcecode for "Blowfish" can be obtained at http://www.counterpane.com. Texts encrypted by EnScrypt are compatible with other implentations of "Blowfish."

EnScrypt (Custom) is for Macintosh developers and script writers who need a secure, fast, and totally flexible environment for encryption. Versions are available which use keys of (40 bits, 56 bits and higher). At the present time, EnScrypt (Custom) is not available outside of the United States because of restrictions on strong cryptography. Prices and terms for licencing available upon request (it's not expensive).

June 3, 1999. Version 1.0 is released

June 18, 1999. Version 1.01 is released. Adds documentation and example scripts for doing encryption, digital signatures, and password authentication. Also includes the FreeBees osaxen.

June 22, 1999. Version 1.02 is released. Fixes a bug. Different versions EnScrypt are now compatible with each other and with other implementations of "Blowfish."

 EnScrypt Syntax and Samples

Following is the Applescript syntax and samples for (EnScrypt Lite). There are more samples in the folder "Demos and Samples." Except for the prefix "HWL", the other versions of EnScrypt are identical.

HWL Make Subkeys string -- Creates the subkeys which do the actual encryption

Result: 'HW!!' -- the result (passed back to the script)

HWL Encrypt String string -- EnScrypt will encrypt any string

subkeys 'HW!!' -- this is the keylist created by ‘make subkeys’

Result: string -- Encrypted text.

HWL Decrypt String string -- this is the encrypted text

subkeys 'HW!!' -- this is the keylist created by ‘make subkeys’

Result: string -- Decrypted text.

set plaintext to "The rain in Spain stays mainly on the plain"

set pskey to "ThisIsMyPasskey"

set keylist to HWL Make subkeys pskey

set cryptstring to HWL Encrypt String plaintext subkeys keylist

set decryptstring to HWL Decrypt String cryptstring subkeys keylist

FreeBees is a collection of tools that performs the indispensable tasks of "hashing" (creating a one-way hash of any text), and "hexing" (translating text to and from its hexadecimal equivalent). Use the hashing routine to create secure and/or verify passwords

Following is the syntax and samples for (FreeBees). There are more samples in the folder "Demos and Samples."

HW Hex String string -- character string

Result: string -- resulting hex string

HW Unhex String string -- Hex string

Result: string -- Character String

HW Initialize Hash

Result: 'HWc!' -- Initialized hash structure

HW Hash String string -- Plain text

with 'HWc!' -- Hash structure

On 1st call -- output of HW Initialize Hash

On subsequent calls -- output of previous call

of HW Hash String

Result: 'HWc!' -- Hash structure

HW Finish Hash

with 'HWc!' -- Hash structure

Output of last call of HW Hash String

Result: string -- hash result -- 20 character text array
