The all-in-one ultimate online toolbox that generates all kind of keys! /microsoft-365-home-premium-product-key-generator.html. Every coder needs All Keys Generator in its favorites! It is provided for free and only supported by ads and donations. I used the standard command 'rand' to generate a random value of size 24 bytes coded in base64 and saved it as a key in a text file, but I don't know how to use this file to encrypt a text message using the command 'enc', and I'm wondering if there is a better way to generate a triple DES key using OpenSSL command line. The key decodes down into 16 characters, so I am assuming its AES128. I have tried to use the key and cyphertext to decode the message using the website “aesencryption.net” and OpenSSL with the following command: openssl enc -d -aes-128-ecb -base64 -in cypherText.txt -out /dev/stdout -pass pass:key.

Thanks for the code. It works like a charm. Used this code to create a triple DES online tool. |
