The Blowfish cipher in C and i386 assembler.In cryptography, Blowfish is a keyed, symmetric block cipher, designed in 1993 by Bruce Schneier and included in a large number of cipher suites and encryption products. While no effective cryptanalysis of Blowfish has been found to date, more attention is now given to block ciphers with a larger block size, such as AES or Twofish.

The key size is between 32 and 448 bits, with 448 bits obviously being the strongest encryption. It is considered very good for smaller amounts of data (like e-mails etc.), but becomes less good with very large amounts of data (several GB's) because of the relatively small block size (64 bits) used in the cipher.

You will have to generate a private and a public encryption key in order to securely send the order information to FastSpring.
There are two ways on how to generate these keys. The easy way or the long way. The easy way is only possible, if your server is supporting openssl functionalities needed for encryption key generation. These openssl functionalities will be detected by the plugin and so, depending on your server, you will either see the “Generate private and public key” button in the plugin settings page or you wont. If you see the button, then you will be able to use the easy way, if you don’t then please look at the instructions for the long way.
Easy way
- click on the “Generate private and public key” button in the plugins settings
- if the key generation was successful, dismiss the alert message and download the public-key.pem file, by clicking on the “Download private and public key” link
- save the plugin settings
- login to your FastSpring dashboard and navigate to Integrations » Store Builder Library. Upload the public-key.pem file to the Public Certificate option.
That’s it! 🙂
Long way
The private and public keys will have to be generated on your computer, so let’s look at how to generate them.
Generate the private/public keys
The generation of these private/public keys differ, depending on which computer operating system you are using. Please follow the instructions for the OS your computer is using.
macOS and Linux
On macOS and on Linux, you should open the terminal program and execute the commands displayed below:
Create a 2048-bit RSA private key. Don’t share this key with anyone, use it only in the EDD FastSpring plugin settings. This key will be used to encrypt the orders. Use this command to generate the privatekey.pem file which will contain your private key. The file will be created in the position, that the terminal is currently located in (usually your home directory).
openssl genrsa -out privatekey.pem 2048
Empire total war product key generator free. Total War: Rome 2 is the sequel to the much loved Rome: Total War. It is a strategy game where players are tasked with raising an empire, maintaining cities and waging war when necessary.The game features many playable factions, each with their own unique units and play style.Total War: Rome 2 features deep, Real Time Strategy combat, letting players control individual groups of men in battle to best maximize their effectiveness against the enemy.It features an amazing 3d campaign map with incredible detail and structure.
Create a 2048-bit RSA public key. Only share this key with FastSpring. FastSpring will use your public key PEM file publiccert.pem to decrypt the orders. The file will be created in the position, that the terminal is currently located in (usually your home directory). After you run this command a few short questions will be presented to you, which you can skip, by hitting “enter” key for each of them.
openssl req -new -key privatekey.pem -x509 -days 3650 -out publiccert.pem
Now that you have generated these keys, you have to configure the EDD FastSpring plugin and the FastSpring Dashboard, so look at these instructions in the sections below.
Windows
For generation of these private/public keys your computer needs OpenSSL. Windows does not have that installed by default, so we will have to do that ourselves.
- Go to this website: https://slproweb.com/products/Win32OpenSSL.html
- In the “Download Win32 OpenSSL” section download the latest appropriate “Light” version of the OpenSSL installer. By “appropriate” I mean the version of Windows you are using (32bit or 64bit). I’m using the 64-bit Windows, so at the time of writing this, the latest version to download is “Win64 OpenSSL v1.1.0f Light”.
- Install the downloaded installer file as you would any other windows application (leave the default installation path, because it will be needed later on). In the last step, you can uncheck the donation option and click on “Finish”.
So, the OpenSSL is now installed on your Windows computer and we can generate the private and public keys.
Click on your Windows start button and search for “Command Prompt” (cmd), right click on the “Command Prompt” and choose to “Run as administrator”. Click on “yes”, when the window for the administration conformation pops up.
Copy and paste this command into the cmd and hit enter (this will position the cmd location to your desktop, where we will generate the private/public keys):
cd %userprofile%Desktop
Generate 448 Bit Encryption Key File
Depending on which version of Windows you have and therefore which version of OpenSSL you installed, you will have to use a specific path to the OpenSSL executable.
By default the paths are:
- If you installed the win32 version, the path will be:
C:OpenSSL-Win32binopenssl.exe - If you installed the win64 version, the path will be:
C:OpenSSL-Win64binopenssl.exe
I’m using the win64 version, so I’ll use that path in the example, if you are using the win32, then just change the “64” in the path to “32”.
Create a 2048-bit RSA private key. Don’t share this key with anyone, use it only in the EDD FastSpring plugin settings. This key will be used to encrypt the orders. Use this command to generate the privatekey.pem file which will contain your private key.
C:OpenSSL-Win64binopenssl.exe genrsa -out privatekey.pem 2048
Create a 2048-bit RSA public key. Only share this key with FastSpring. FastSpring will use your public key PEM file publiccert.pem to decrypt the orders. After you run this command a few short questions will be presented to you, which you can skip, by hitting “enter” key for each of them.
C:OpenSSL-Win64binopenssl.exe req -new -key privatekey.pem -x509 -days 3650 -out publiccert.pem
Now that you have generated these keys, you have to configure the EDD FastSpring plugin and the FastSpring Dashboard, so look at these instructions in the sections below.
EDD FastSpring settings
Generate 448 Bit Encryption Key Generator
Open the privatekey.pem file you generated earlier with a text editor (right-click to the file and choose to open with any text editor like Sublime Text or native text editor of your OS). Copy the content of this file.
Go to your WordPress admin dashboard and navigate to the EDD FastSpring plugin settings (Downloads » Settings » Payment Gateways » FastSpring).
Paste the private key content into the Private encryption key setting. Save the settings.
Jun 08, 2015 how to generate secret key? Closed nelsonic opened this issue Jun 8, 2015 10 comments Closed how to. Just for reference as I'm learning about JWT as well, i found it interesting that i can generate a JWT token server side, send it to client to store as cookie, and then do this in browser dev tools. Sep 17, 2018 Clients security with JWT. You might be asking yourself what is JWT? JWT is JSON Web Token. It’s a token that only the server can generate, and can contain a payload of data. https://monsbronepter.tistory.com/1. What is secret key for JWT based authentication and how to generate it? Ask Question. Now what is this secret key and how to generate this secret key?? The algorithm (HS256) used to sign the JWT means that the secret is a symmetric key that is known by both the sender and the receiver. It is negotiated and distributed out of band. The signing key is a byte array of any value or length you wish. Most JWT libraries allow you to use any string as key, which is converted to byte array. To generate a secure 20 byte key, bs64 encoded. Dd if=/dev/random bs=20 count=1 status=none base64.
