Ruby SHA1 标志返回与 OpenSSL 标志不同的结果

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

我得到这个结果:

然后通过运行这个 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)

结果不同:

谁能帮帮我？为什么我在 ruby 部分做错了？我想复制linux命令行命令!

找到解决方案...signing 与 private_encrypt 不同......但仍然不明白为什么:)

require 'openssl'
require 'base64'

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