While Encrypting a File with a Password from the Command Line using OpenSSLis very useful in its own right, the real power of the OpenSSL library is itsability to support the use of public key cryptograph for encrypting orvalidating data in an unattended manner (where the password is not required toencrypt) is done with public keys.

The Commands to Run
Generate a 2048 bit RSA Key
You can generate a public and private RSA key pair like this:
openssl genrsa -des3 -out private.pem 2048
That generates a 2048-bit RSA key pair, encrypts them with a password you provideand writes them to a file. You need to next extract the public key file. You willuse this, for instance, on your web server to encrypt content so that it canonly be read with the private key.
Oct 09, 2019 How to Generate & Use Private Keys using OpenSSL's Command Line Tool. These commands generate and use private keys in unencrypted binary (not Base64 “PEM”) PKCS#8 format. The PKCS#8 format is used here because it is the most interoperable format when dealing with software that isn't based on OpenSSL. 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 The online decoder gives me unreadable. Using key file as password with OpenSSL. Ask Question Asked 6 years, 10 months ago. I know how to decrypt if the key is a passphrase by using. Openssl enc -d -aes-256-cbc -in file.out In this case, the key is a binary file. How do I use it? How do you use the AES key wrap cipher with the OpenSSL command line utility?

Creating an SSH key on Windows 1. Check for existing SSH keys. You should check for existing SSH keys on your local computer. You can use an existing SSH key with Bitbucket Server if you want, in which case you can go straight to either SSH user keys for personal use or SSH access keys for system use. Open a command prompt, and run. To Generate an SSH key in Windows 10, Open a new command prompt. Type ssh-keygen and hit the Enter key. The app will ask for the save location, offering C:usersyour user name.sshidrsa by default. Next, you will be prompted to enter a passphrase. You can just hit the Enter key to skip it. Finally, you will see the fingerprint for your key. Sep 26, 2019 Manually generating your SSH key in Windows. Modified: 26 Sep 2019 21:20 UTC. For Type of key to generate, select SSH-2 RSA. Installation package comes with SSH. Using Git Bash, which is the Git command line tool, you can generate SSH key pairs. Git Bash has an SSH client that enables you to connect to and interact with Triton. I need to generate public key to set up in ssh. How do I do it from windows command prompt? I tried using ssh-keygen -t rsa from c: but received a message ssh-keygen is not recognized as an internal or external command, operable program or batch file. 
This is a command that is
openssl rsa -in private.pem -outform PEM -pubout -out public.pem
The -pubout flag is really important. Be sure to include it.
Next open the public.pem and ensure that it starts with-----BEGIN PUBLIC KEY-----. This is how you know that this file is thepublic key of the pair and not a private key.
To check the file from the command line you can use the less command, like this:
less public.pem
Openssl Base64 Example
Do Not Run This, it Exports the Private Key
A previous version of the post gave this example in error.
openssl rsa -in private.pem -out private_unencrypted.pem -outform PEM
The error is that the -pubout was dropped from the end of the command.That changes the meaning of the command from that of exporting the public keyto exporting the private key outside of its encrypted wrapper. Inspecting theoutput file, in this case private_unencrypted.pem clearly shows that the keyis a RSA private key as it starts with -----BEGIN RSA PRIVATE KEY-----.
Visually Inspect Your Key Files
It is important to visually inspect you private and public key files to makesure that they are what you expect. OpenSSL will clearly explain the nature ofthe key block with a -----BEGIN RSA PRIVATE KEY----- or -----BEGIN PUBLIC KEY-----.
You can use less to inspect each of your two files in turn:
less private.pemto verify that it starts with a-----BEGIN RSA PRIVATE KEY-----less public.pemto verify that it starts with a-----BEGIN PUBLIC KEY-----
The next section shows a full example of what each key file should look like.
The Generated Key Files
Openssl Generate Rsa Key Pair
The generated files are base64-encoded encryption keys in plain text format.If you select a password for your private key, its file will be encrypted withyour password. Be sure to remember this password or the key pair becomes useless.
The private.pem file looks something like this:
The public key, public.pem, file looks like:
Protecting Your Keys
Aes Key Absent
Depending on the nature of the information you will protect, it’s important tokeep the private key backed up and secret. The public key can be distributedanywhere or embedded in your web application scripts, such as in your PHP,Ruby, or other scripts. Again, backup your keys!
Remember, if the key goes away the data encrypted to it is gone. Keeping aprinted copy of the key material in a sealed envelope in a bank safety depositbox is a good way to protect important keys against loss due to fire or harddrive failure.
Oh, and one last thing.
