While Encrypting a File with a Password from the Command Line using OpenSSL is very useful in its own right, the real power of the OpenSSL library is its ability to support the use of public key cryptograph for encrypting or validating data in an unattended manner (where the password is not required to encrypt) is done with public keys. On my Mac I ran the following commands to obtain both private dsapriv.pem and public dsapub.pem keys. Openssl dsaparam 1024 /dev/random dsaparam.pem openssl gendsa dsaparam.pem -out dsapriv.pem openssl dsa -in dsapriv.pem -pubout -out dsapub.pem Needless to say, keep your private key in secure location and make sure you have a backup of it!

This module allows one to (re)generate OpenSSL private keys. One can generate RSA), DSA, ECC or EdDSA private keys. Keys are generated in PEM format. Please note that the module regenerates private keys if they don’t match the module’s options. To generate private (d,n) key using openssl you can use the following command: openssl genrsa -out private.pem 1024 To generate public (e,n) key from the private key using openssl you can use the following command: openssl rsa -in private.pem -out public.pem -pubout. The gendsa command generates a DSA private key from a DSA parameter file (which will be typically generated by the openssl dsaparam command). Encrypts the private key with the DES, triple DES, or the IDEA ciphers respectively before outputting it. A pass phrase is prompted for. Generating the Public Key - Windows 1. At the command prompt, type the following: openssl rsa -in rsa.private -out rsa.public -pubout -outform PEM 2. The public key is saved in a file named rsa.public located in the same folder. Generating the Private Key - Linux 1. Open the Terminal. Navigate to the folder with the ListManager directory. Generating private keys with openssl Keys are the basis of public key algorithms and PKI. Keys usually come in pairs, with one half being the public key and the other half being the private key. With OpenSSL, the private key contains the public key information as well, so a public key doesn’t need to be generated separately.

Generate Dsa Private Key Openssl

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

Openssl Generate Keypair

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.

Export the RSA Public Key to a 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:

To transfer a license simply make sure that think-cell is not accessible from the old machine anymore, e.g., by uninstalling it. Then download the software to the new machine, install it and activate it using your existing license key. You do not have to inform us about this transfer. Think-cell requires a valid license key to run. The license key is checked on each start of Microsoft PowerPoint or Microsoft Excel. If no valid license information is found on your system or if the license key is about to expire, the think-cell license key window is displayed.

less public.pem

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-----.

These tools are used for the graphic making of any game. There are many tools on the window of the software. Rpg maker vx ace key generator.

You can use less to inspect each of your two files in turn:

  • less private.pem to verify that it starts with a -----BEGIN RSA PRIVATE KEY-----
  • less public.pem to 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

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

Openssl Create Key Pair

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.

If you, dear reader, were planning any funny business with the private key that I have just published here. Know that they were made especially for this series of blog posts. I do not use them for anything else.
