Openssl tutorial: Generate and Install Certificate on Apache Server in 8 Easy Steps 1. Usually Port 443 will be used for secure channel communication which is also known as https Port. Hence it is a common practice to install a SSL Certificate before putting any content in Internet through web server. This will safeguard the communication between server and client. It will encrypt all the communication happening between server and client and hence will make difficult for anyone trying to steal or read the data. SSL Certificate is used secure traffic between client and Server.

PKCS - Public-Key Cryptography Standards Why do we need SSL Certificate This tool will use OpenSSL Library to implement its tasks.In most of the Linux systems, this tool will be installed by default. openssl is an opensource command line tool in linux primarliy used to generate ssl certificate with the help of private key and certificate signing request(CSR) file. �F݇��.In this article, I will take you through 25+ Popular Examples of Openssl Commands in Linux.

1 bob bob 128 Mar 22 14:03 reply_secret.enc A file name to save the decrypted output to via redirectionīob $ openssl rsautl -encrypt -inkey alice_public.pem -pubin -in reply_secret.txt -out reply_secret.enc.Bob's own private key (for decryption, since it was encrypted using Bob's public key).The encrypted file (which he got from Alice).He needs to provide the following information to the utility: 1 bob bob 128 Mar 22 13: 59 top_secret.encīob $ Step 5: Decrypt the file using a private keyīob needs to do his part by decrypting the message using OpenSSL, but this time using the -decrypt command-line argument. If Bob uses the usual methods to try to open and view the encrypted message, he won't be able to read it: Remember, even if the file is intercepted, its contents are encrypted, so the contents can't be revealed: alice $ scp top_secret.enc bob /path / Now Alice needs to send this encrypted file to Bob over a network, once again, using the scp command to copy the file to Bob's workstation. It's safe to delete the original file with the secret message to remove any traces of it: alice $ rm -f top_secret.txt So, Alice must extract her public key and save it to a file using the following command:Ġ0000000 9e 73 12 8f e3 75 4d 29 4d 26 3e bf 80 4e a0 c5 |.s.uM )M &>.N. Remember, the public key is the one you can freely share with others, whereas you must keep your private key secret. This demo uses a Fedora machine with OpenSSL installed.

OpenSSL is an amazing tool that does a variety of tasks, including encrypting files. Hence the descriptor "key-pair" the set of keys goes hand-in-hand. The only way you can decrypt your sender's encrypted message is by using your private key. If someone wants to communicate sensitive information with you, you can send them your public key, which they can use to encrypt their messages or files before sending them to you. The other, the private key, is supposed to be a secret and never shared. One is the public key and can be freely shared with anyone you want to communicate with secretly.

Public-key encryption uses two sets of keys, called a key pair.
