我想先将字符串转换为字节数组，然后才能使用私钥对其进行签名，但我以前没有这样做过。我的代码如下所示，任何人都可以告诉我如何做到这一点。谢谢。

require 'openssl'
require 'base64'
require 'digest/sha1'

@date = Date.today.strftime("%m/%d/%Y")
text_to_sign = "#{@order.phone_no}" + "#{@order.name}" + "#{@order.pay_type}" + "#{@order.pay_type}" + "1" + "MABIRA" + "81W30DI846" + "#{@date}" + "PULL" + "1" + "#{@cart.total_price}" + "#{@order.phone_no}" + ""
password = 'secret'

#converting the string to byte array
byte[] buff => new byte[1024]
text = buff.text_to_sign


private_key = OpenSSL::PKey::RSA.new(File.read('Private.key'), password)
ciphertext = private_key.private_encrypt(text)
ciphertext.encoding
signed_text = Base64.encode64(ciphertext).gsub("\n", '')
puts signed_text
signed_text
