Ruby SHA1符号返回的结果与OpenSSL符号不同

Question

当我在linux命令行执行openssl命令时:

echo -n "aaaaaa" | /usr/bin/openssl dgst -sha1 -sign myprivatekey.pem | /usr/bin/openssl enc -base64 -A

我得到这样的结果:

并运行以下ruby脚本:

require 'openssl'
require 'base64'
pkey = OpenSSL::PKey::RSA.new(File.read("myprivatekey.pem"))
plaintext = OpenSSL::Digest::SHA1.new("aaaaaa").digest
enc = pkey.private_encrypt(plaintext)
puts Base64.encode64(enc)

结果是不同的:

有人能帮我吗?为什么我在红宝石的部分做错了?我要复制linux命令行命令!

找到解决方案了…签名不同于private_encrypt…但还是不明白为什么:)

require 'openssl'
require 'base64'
pkey = OpenSSL::PKey::read(File.read("privatekey.pem"))
enc = pkey.sign(OpenSSL::Digest::SHA1.new,"aaaaaa")       
puts Base64.encode64(enc)
