ruby中rsa加签解签方法

# coding:utf-8
require 'openssl'
require 'base64'
# rsa签名，文本内容和私钥路径
def rsa_sign(data,private_key_path)
private_key = File.read(private_key_path)
pri = OpenSSL::PKey::RSA.new(private_key)
sign = pri.sign('sha1', data.force_encoding("utf-8"))
# signature = CGI.escape(Base64.encode64(sign))
signature = Base64.encode64(sign)
signature = signature.gsub!("\n",'')
return signature
end

# rsa验签，文本内容和签名内容，公钥路径
def rsa_verify(data,sign,public_key_path)
public_key = File.read(public_key_path)
pub = OpenSSL::PKey::RSA.new public_key
digester = OpenSSL::Digest::SHA1.new
sign = Base64.decode64(sign)
return pub.verify(digester, sign, data)
end

# rsa签名验签测试
def test_rsa data = "123"
puts rsa_sign(data,'rsa_private_key.pem')
sign= "KrXGYocurl3wl6w96dkr906lE1RErlQS2T5zalFIALR6Re78qCQlihIN+iXDyQK6OKc8sQlWUgdARslL0n1WFGM36OWZfhb2dG4mpFaKE3oq88JSrxTR0uAQrR/m13qe5QxpN30gCsrNlAqSlUER8TS8cfI9eWtkTQqz6TWaGio="
puts rsa_verify(data,sign,'rsa_public_key.pem')
end
