ruby的加密方法整理（des rsa加密 加签）

# coding:utf-8
require 'openssl'
require 'base64'
#des加密并且base64编码
def des_encrypt des_key, des_text
  des =OpenSSL::Cipher::Cipher.new("DES-ECB")
  des.encrypt
  des.key=des_key
  des_text="#{des_text}"
  result = des.update(des_text)
  result << des.final
  data=Base64.encode64(result)
  data.gsub!("\n",'')
end
#rsa加签 base64编码
def rsa_sign data, key
  rkey =OpenSSL::PKey::RSA.new key
  sign= rkey.sign('sha1',data.force_encoding("utf-8"))
  signature = Base64.encode64(sign)
  signature.gsub!("\n",'')
end
#rsa加密
def rsa_encrypt data, key
  rsa=OpenSSL::PKey::RSA.new key
  result = Base64.encode64(rsa.public_encrypt data)
  result.gsub!("\n",'')
end
