An additional point on Blowfish encryption usage: 7. When encrypting/decrypting multiple records at once via Blowfish in a looping process like DO WHILE, you must first delete any controlling compound index, like a compound CDX index, ...

I got Blowfish to work fine. See separate thread, "How to work with Blowfish".

Reviewing some of the comments made in other threads about encryption, I offer these observations: 1. Blowfish is an encryption system that is approved in the USA for health-related applications requiring HIPAA compliance. Some of the other encryption systems mentioned here ...

The earlier problem I posted on another thread about experiencing excessive processing time for encryption/decryption with Blowfish was caused by my error in handling the encryption of memos. After eliminating my error (I had incorrectly assumed that each memo field had to have a fixed ...

After some testing, it seems the only special "tricks" needed for working with Blowfish are that A) all fields must be of char data type; B) all fixed-length fields to be encrypted in a DBF must be 8 bytes long or some multiple of 8 bytes in length (16, 24, ...

Reinaldo,

Thanks for the excellent info. I'll discuss it will my customer. Hopefully, they'll increase my project's budget to allow using ADS with all of its advantages.

All the best,

I see we are running two different threads on the same subject and I have already shown that ADS is FIPS compliant, however, here is more information on ADS encryption: Advantage provides the capability to encrypt tables and associated data. Data encryption is just one part of the process of creatin...

... systems that the govt. has found acceptable under HIPAA. The approved list of encryption systems includes DES (though it is being deprecated), Blowfish, RSA, RC5, PGP and IDEA. Other proprietary encryption systems are generally not allowed, unless certified by an independent encryption review ...

The advantages of the Blowfish encryption system (available in Harbour) are: 1. U.S. government regulations covering privacy and encryption rules (like HIPAA - the Health Insurance Portability and Accountability Act) have found Blowfish ...

I posted this code some time ago which has served me well..

Roger; ADS remote as well as the free local server RDDs allow you to encrypt a .dbf. Here is some text from the help file: Advantage provides security for your data in a number of important ways. Some of these are associated with how Advantage transmits data across the network, and others are associ...

Since I can't get a solution to the hugely excessive length of the Blowfish key (over 4000 bytes) that makes encryption/decryption painfully slow, can anyone recommend another widely recognized encryption system that works with FWH?

I sent a private email to Przemek about this. He is the expert on Blowfish encryption for Harbour, and If he offers a solution, I'll post it here.

Here is some test code that shows the problem: Function BlowfishTest()    local cBfKey := hb_blowfishKey( "fivewin" )    MsgInfo(cBfKey,"cBfKey")    Msginfo(LEN(cBfKey),"LEN(cBfKey)")    // ...
