v0.2 Encryption Types and A Bit About Encryption

In version 0.2, there is a new configuration option:

CarrierWave::SecureFile.configure do |config|
	config.encryption_type = "blowfish"
end

encryption_type can be:

• blowfish
• rijndael
• gost

If this parameter is not set, >0.2 will set the encryption type to blowfish. Blowfish is default as it is the fastest.

In brief testing, I got the following results on a mediocre upload speed (maybe around 6mbps?) with a 1.1mb JPG file:

• Blowfish: 12942ms Upload, 9872ms Download
• Gost: 23035ms Upload, 15473ms Download
• Rijndael: 43207ms Upload, 46816ms Download

While Rijndael and Gost are more complex algorithms that may provide more security, Blowfish typically provides the fastest encryption and decryption.
