Erlang - 导入GPG公钥

时间:2012-06-10 03:56:50

标签: erlang rsa gnupg public-key

我正在尝试在Erlang中做一些与公钥相关的事情,他们要求我跟踪公钥。根据{{​​3}},我应该可以使用file:read_file/1public_key:decode_pem/1导入PEM格式密钥。问题是,当我尝试导入GPG公钥时,我没有得到结果。

我有一个名为inaimathi.pubkey的文件,内容如下:

似乎格式正确,但我得到的结果是

1> {ok, GpgBin} = file:read("inaimathi.pubkey").
{ok,<<"-----BEGIN PGP PUBLIC KEY BLOCK-----\nVersion: GnuPG v1.4.11 (GNU/Linux)\n\nmQINBE9NBIQBEADMSzN6b0FaPP0rGiLDWKf"...>>}
2> public_key:pem_decode(GpgBin).
[]

根据文档,我希望这会返回RSAEntry,然后我可以将其解码为公钥。通过这种机制导入公钥是否需要做些什么? GPG密钥实际上是有效的PEM文件吗?我错过了别的什么吗?

1 个答案:

答案 0 :(得分:3)

ASCII装甲和PEM非常相似。您只需要更改BEGIN / END标记,剥离PGP标头和校验和(校验和是最后一行=Zqph),然后添加PEM标头。因此,您必须将inaimathi.pubkey更改为此文件:
