Go back to the bin folder that’s in the OpenSSL folder and search for the output file you just created! -aes-256-cbc is an option we give it. OpenSSL is a software library for applications that secure communications over computer networks against eavesdropping or need to identify the party at the other end. Perfect Forward Secrecy. OpenSSL est une boîte à outils de chiffrement comportant deux bibliothèques, libcrypto et libssl, fournissant respectivement une implémentation des algorithmes cryptographiques et du protocole de communication SSL/TLS, ainsi qu'une interface en ligne de commande, openssl. First we create a test file that is going to encrypted Now we encrypt the file: Here we used the ‘aes-256-cbc’ symmetric encryption algorithm, there are quite a lot of other symmetric encryption algorithms available. My text file will be named AAA as an example. Just suggestion, you could mention in step 1 that in windows 10 it will be called “This Pc” , it took me just a couple extra minutes to find it because I had just installed windows 10 and I was not familiar yet as to where to find that information. Encryption is when data, in this case a text file, is converted into cipher text. Since you cannot delete any characters entered.Otherwise I think you did a good job of explaining each step. To learn more, see our tips on writing great answers. To get the default—though fairly weak—RC2-40 encryption, you just tell openssl where the message and the certificate are located. I also assume that one can encrypt one way, then encrypt a second time using a different method for added protection. OpenSSL is a command line tool we can use as a type of "bodyguard" for our webservers and applications. - forgoer/openssl By default OpenSSL will work with PEM files for storing EC private keys. openssl is the actual command.
