I would hope that one of us could provide you something given a week or so... very busy with work currently but I'm sure I could do something in time.

Leon: I suggest that you write a program that uses file descriptors for IO? I'd write it in C.

The Windows app can call external Windows commands but we cannot call APIs or extend the functionality programmatically. Functionally it works, but it doesn’t scale as each time you call OpenSSL.exe it takes about a second and spikes the CPU. The application we are using is required to process 6000 records every hour. I have two tests set up: 1. A batch file which runs 6000 times, repeatedly running the following command: Openssl.exe aes-256-cbc -a -e -k eiccmkjd94jfgniw03ljkdlfutcnv320 –in test.txt 2. A text file with the following line repeated 6000 times, which I paste into the OpenSSL CLI: aes-256-cbc -a -e -k eiccmkjd94jfgniw03ljkdlfutcnv320 –in test.txt When I use the batch file which invokes OpenSSL.exe 6000 times, it takes several hours to complete and spikes the CPU significantly. It seems to be the initialisation of the OpenSSL.exe program rather than the encryption however, as if I paste in the text file to the OpenSSL.exe CLI it completes in several seconds and takes very little CPU. What I need is a way of running OpenSSL.exe as a process which I can pass parameters to on STDIN, and output parameters to STDOUT. I would like to be able to call another batch file or program with the unencrypted data as the input parameter which would then pass this to the running “service”, retrieve the encrypted data result from this “service” and pass it as the output. Can anyone enlighten me on a potential solution for this?
