If the SSH Server does not allow you to connect using password authentication, or does not allow you to upload the key, you will need to send the public key to the server administrator using an alternate method of communication. The attack is enabled by what the researchers described as a "severe vulnerability" in the OpenSSL innards that carry out authentication based on the RSA public key encryption algorithm. The code is fairly simple, a user enters an encryption key (which basically tells the program how to scramble the text, using an algorithm), then the text to be encrypted. In the first part of this article, I’ll share with you a cautionary tale on the importance of debugging and visually verifying that your convolutional neural network is “looking” at the right places in an image. pem > server_key.
