This truly is the swiss army knife of encryption tools. On my Mac OS X system, the default openssl install supports and impressive set of 49 algorithms to choose from. OpenSSL in Ruby 1.9.2 for your Ruby on Rails.In the mean time, check out these API references for both PHP and Ruby. In future articles, we will explore the usage of OpenSSL for encryption and verification in website projects. Compatible SSL libraries are also built into Java and even the Microsoft platforms. It’s built into the majority of platforms, including Mac OS X, Linux, FreeBSD, iOS, and Android.
The OpenSSL library is a very standardized open source security library. But if you’re already using AES-256, there’s no reason to change” ( Another New AES Attack, July 30, 2009). AES-128 provides more than enough security margin for the foreseeable future. The file is very strongly encrypted for normal purposes assuming that you picked a good passphrase.Īccording to Bruce Schneier, “…for new applications I suggest that people don’t use AES-256. This example uses the Advanced Encryption Standard (AES) cipher in cipher-block chaining mode. Openssl aes-128-cbc -d -in 128 -out Archive.zip To decrypt it (notice the addition of the -d flag that triggers a decrypt instead of an encrypt action): Openssl aes-128-cbc -in Archive.zip -out 128 To do this using the OpenSSL command line tool, you could run this: In terminal, suppose you wanted to encrypt a file with a password (symmetric key encryption). So there is no reason not to use it to add additional security to your web applications. Support for the library are included by default in PHP and Ruby.
#The command to encrypt xfile is how to
Do you know how to use OpenSSL to protect sensitive information in storage instead of just in transit across the network? In fact, your can use the OpenSSL command line too to encrypt a file on your Mac OS X, Linux, or FreeBSD based computer.
