我無法在Erlang中「pem_entry_decode」GPG公鑰。通過OpenSSL生成的公鑰工作正常。我已經按照Erlang - Importing GPG Public Key中的建議修復了GPG密鑰。在Erlang中解碼PGP密鑰

#!/usr/local/bin/escript 

main(_) -> 
    [application:start(X) || X <- [crypto, public_key, ssl]], 
    Msg = list_to_binary("Hello World!"), 
    %{ok, FileContents} = file:read_file("public_openssl.pem"), 
    {ok, FileContents} = file:read_file("public_gpg.asc"), 
    show(FileContents), 
    [Entry] = public_key:pem_decode(FileContents), 
    show(Entry), 
    Key = public_key:pem_entry_decode(Entry), 
    show(Key), 
    EM = public_key:encrypt_public(Msg, Key), 
    show(EM). 

show(Something) -> 
    io:format("~p~n", [Something]). 

錯誤:

escript: exception error: no match of right hand side value 
       {error, 
        {asn1, 
         {wrong_tag, 
          {{expected,16},{got,131097,{131097,<<"\r">>}}}}}}

源代碼是否與錯誤堆棧一致?錯誤堆棧提到public_key:der_decode,而源代碼提到public_key:pem_decode ... – user803422 2013-03-28 11:57:10

我檢查了public_key.erl。 'der_decode'由'pem_entry_decode'調用。不知道爲什麼它不顯示整個堆棧。 – ram 2013-03-28 12:49:50

我建議你嘗試在一個更新的Erlang版本中重現這個問題,比如在R16B中。有消息稱現在對各種DER編碼的東西更加友好,甚至有點畸形。 – Keynslug 2013-06-10 12:48:36

從你:

{ok, FileContents} = file:read_file("public_gpg.asc") 

FileContents,選擇前16個字符。
