Гибберская библиотека предоставляет хороший алгоритм CBC ...

// In Jascascript
GibberishAES.enc("Made with Gibberish\n", "password");
// Outputs: "U2FsdGVkX1+21O5RB08bavFTq7Yq/gChmXrO3f00tvJaT55A5pPvqw0zFVnHSW1o"

# On the command line
echo "U2FsdGVkX1+21O5RB08bavFTq7Yq/gChmXrO3f00tvJaT55A5pPvqw0zFVnHSW1o" | 
  openssl enc -d -aes-256-cbc -a -k password

Как я могу сделать эту расшифровку в рубине? Простой способ не работает ...

require 'openssl'

def aes(m,k,t)
  (aes = OpenSSL::Cipher::Cipher.new('aes-256-cbc').send(m)).key = k
  aes.update(t) << aes.final
end

def encrypt(key, text)
  aes(:encrypt, key, text)
end

def decrypt(key, text)
  aes(:decrypt, key, text)
end

def p k
  Digest::SHA256.digest(k) ## what goes here???
end

require 'base64'
def t x
  ## also tried.. simply returning x...
  Base64.decode64(x)      
end


text = "U2FsdGVkX1+21O5RB08bavFTq7Yq/gChmXrO3f00tvJaT55A5pPvqw0zFVnHSW1o"
pass = "password"

decrypt(p(pass), t(text))
