Ruby relies on two known libraries to encrypt and decrypt data: gibberish and ezcrypto. Let’s take a look at two implementations in order to figure out how they are both different from each other.

First method of encryption

require ‘gibberish’
text = “text to be encrypted”

aes_key = Gibberish::AES.new(“My Key”)
aes_cypher = aes_key.enc(text)
aes_key.dec(aes_cypher)

Second method of encryption

require ‘ezcrypto’
text = “text to be encrypted”

ez_key = EzCrypto::Key.with_password ‘My key’, ‘My Salt’
ez_cypher = ez_key.encrypt(text)
ez_key.decrypt(text)

It is important to note that both of these libraries required to have underlining library such as C OpenSSL.

Gibberish library can encrypt and decrypt files by accepting file path, so it is useful for working with files.
