Tag: decryption

A few months back I had a Korn shell script which used OpenSSL to encrypt some text using AES 256 CBC.
I managed, through the power of stackoverflow.com and various other blogs, to write a Java routine to perform the exact same encrypt/decrypt.
This allowed me to encrypt in Korn on Linux and decrypt in Java which was running inside a SAP Netweaver application server, or the other way around (encrypt in Java and decrypt in Korn using OpenSSL).

About 2 months after that, I needed the same set of routines to be written in PowerShell, allowing the same encrypted text to be encrypted on Linux with OpenSSL and decrypted on Windows in PowerShell (no need for OpenSSL).

I forked the PowerShell code which did the initial encryption and wrote the decryption routine which I’ve published as a Github gist here:
