在Ruby中，我有简单的旧源代码行创建RSA公钥或私钥：
OpenSSL::PKey::RSA.new(File.read(key_file))
我的RSA公钥和私钥格式如下，我使用与MRI和Jruby完全相同的密钥文件：
-----BEGIN RSA PRIVATE KEY-----
MIIEvwIBADANBgkq...
-----END RSA PRIVATE KEY-----
-----BEGIN PUBLIC KEY-----
MIIBIjANBgkqh...
-----END PUBLIC KEY-----
当我在MRI v2.4.0上运行它时 - 任何问题，我可以实例化公钥和私钥：
$> irb
> k = OpenSSL::PKey::RSA.new(File.read("private.pem"))
=> #<OpenSSL::PKey::RSA:0x007fda1096a6a8>
> k = OpenSSL::PKey::RSA.new(File.read("public.pem"))
=> #<OpenSSL::PKey::RSA:0x007fda1096a6a8>
但是使用Jruby 9.0.4.0和9.1.8.0我可以成功启动公共但在init私钥上失败：
> set JRUBY_OPTS=-J-Djruby.openssl.debug=true
> irb
irb(main):001:0> require "openssl"
using provider: BC version 1.56
irb(main):002:0> k = OpenSSL::PKey::RSA.new(File.read("public.pem"))
=> #<OpenSSL::PKey::RSA:0x1c9e76b>
但是创建私钥对象失败了：
irb(main):003:0> k = OpenSSL::PKey::RSA.new(File.read("private.pem"))

然后我尝试使用私钥，我从PEM文件中删除了----- BEGIN RSA PRIVATE KEY -----和----- END RSA PRIVATE KEY -----我可以在Jruby上执行此操作：
irb(main):005:0> require "base64"
=> true
irb(main):006:0> k = OpenSSL::PKey::RSA.new(Base64.decode64(File.read("private.pem")))
=> #<OpenSSL::PKey::RSA:0x1cff11c>
irb(main):007:0> k.private?
=> true
是否可以通过任何方式启用Jruby OpenSSL自动检测PEM文件格式并加载Base64私钥？这是令人沮丧的公钥，Base64格式成功打开，私钥没有。
答案 0 :(得分：0)
好吧，我决定采用这种解决方法，而不是最好看的代码，但它确实有效：
class RSA_Base64_Key
def self.rsa_new key_text
if key_text.is_a?(String) && key_text.include?('-----BEGIN RSA PRIVATE KEY-----')
key_text.gsub!('-----BEGIN RSA PRIVATE KEY-----', '')
key_text.gsub!('-----END RSA PRIVATE KEY-----', '')
key_text = Base64.decode64(key_text)
end
OpenSSL::PKey::RSA.new(key_text)
end
end
if RUBY_ENGINE == 'jruby'
RSA_Base64_Key.rsa_new(File.read(key_file))
else
OpenSSL::PKey::RSA.new(File.read(key_file))
end
