Have a look in the demos/encrypt folder: https://github.openssl.org/openssl/openssl/tree/master/demos/encrypt There has been an amount of effort put into updating these for 3.0 & later.  There is more to do. Pauli On 10/4/22 23:50, Kenneth Goldman wrote: Anyway, I'm trying to encrypt/decr

Thank you and Kenneth for your replies. I was given this task by someone with all of these specifics, including the site to download the library. Most of the terminology about encryption I'm not familiar with, but I'm learning. I've passed both of your posts and the wisdom in them on to him to

Hi everyone, I am looking for a sample source file which encrypts/decrypts a String with DES (or better triple DES). I could not find anything useful on google, the only information I have at the moment are the man pages (crypto(3) and des(3)). I don't want to encrypt/decrypt using the openssl
