Encryption / decryption of token. Works fine in console, fails when run through passenger and stored in DB.

encrypt-token.rb

  def encrypt_token
    aes = OpenSSL::Cipher.new('AES-256-CBC')
    aes.encrypt
    aes.key = Rails.application.config.shopify.secret
    aes.iv = iv = aes.random_iv
    encrypted = aes.update(self[:token])
    encrypted << aes.final
    encoded = Base64.strict_encode64(iv + encrypted)
    self.send(:token=, encoded)
  end

  def decrypt_token
    t = self[:token]
    decoded = Base64.strict_decode64(t)
    aes = OpenSSL::Cipher.new('AES-256-CBC')
    aes.decrypt
    aes.key = Rails.application.config.shopify.secret
    aes.iv = decoded.slice!(0,16)
    decrypted = aes.update(decoded)
    decrypted << aes.final
    decrypted
  end
