是否有perl实现的SHA256withRSA [英] Is there a perl implementation of SHA256withRSA

问题描述

我需要能够创建JSON Web令牌签名（只接受 RSASSA- PKCS1-V1_5-SIGN with the SHA-256 hash function' signatures），但是这个任务的明显CPAN竞争者（ Crypt :: RSA ）只会使用 MD2，MD5或SHA1 。

有什么另一个图书馆在哪里，会做我想要什么？

解决方案

如果需要，我应该能够做一些黑客来到那里，但这不会太漂亮。我可以找到一个我想要的模块： Crypt :: OpenSSL :: RSA

  my $ rsa = Crypt :: OpenSSL :: RSA-> new_private_key（$ key）; 
 $ rsa-> use_sha256_hash; 
 my $ signature = $ rsa-> sign（$ message）; 
  

比扩展Crypt :: RSA容易得多，但很奇怪。 / p>

I need to be able to craft JSON Web Token signatures (which only accepts 'RSASSA-PKCS1-V1_5-SIGN with the SHA-256 hash function' signatures), but the obvious CPAN contender for this task (Crypt::RSA) will only generate signatures using MD2, MD5 or SHA1.

Is there another library somewhere that will do what I want? If necessary I should be able to do a bit of hacking to get there, but that wouldn't be too pretty.

解决方案

I was able to find a module that did what I wanted: Crypt::OpenSSL::RSA

my $rsa = Crypt::OpenSSL::RSA->new_private_key($key);
$rsa->use_sha256_hash;
my $signature = $rsa->sign($message);

So much easier than extending Crypt::RSA, but it was oddly kind of difficult to find.
