密码箱 3 无法加载公钥 - 流读取错误

问题描述

好吧，我用 openssl 生成了一个密钥对

Well i generated a keypair with openssl

openssl genrsa -des3 -out _private.pem 1024

openssl rsa -pubout -in _private.pem -out public.pem

当我尝试使用以下过程加载密钥时，它总是在 Signatory1.LoadKeysFromStream(f, [partPrivate]);

When i try to load the key with the following procedure it always says "Stream reading Error" at line Signatory1.LoadKeysFromStream(f, [partPrivate]);

var
  f: TMemoryStream;
  Signatory1: TSignatory;
  codecRSA: TCodec;
  CryptographicLibrary1: TCryptographicLibrary;
  base64Ciphertext: string;
begin
   f:= TMemoryStream.Create;
   f.LoadFromFile('C:OpenSSL-Win32inprivate.pem');

  codecRSA :=TCodec.Create(nil);
  CryptographicLibrary1 := TCryptographicLibrary.Create(nil);
  Signatory1 :=TSignatory.Create(nil);

  //=============TCodec===================
  codecRSA.CryptoLibrary  := CryptographicLibrary1;
  codecRSA.StreamCipherId := 'native.RSA';
  codecRSA.ChainModeId:= 'native.CBC';
  codecRSA.AsymetricKeySizeInBits := 1024;

  //====Signatory1=====================
  Signatory1.Codec :=codecRSA;
  //===Load public key=============
  Signatory1.LoadKeysFromStream(f, [partPrivate]);
end;

有什么建议吗?我正在使用 Delphi XE7 和来自 Github 的最新版本的 Lockbox 3

Any suggestions? I am using Delphi XE7 and the latest release of Lockbox 3 from Github

推荐答案

根据我的经验，LockBox 3 在使用 OpenSSL 生成的密钥时需要一个 PKCS#1 公钥.您必须先将公钥转换为 PKCS#1，然后 Lockbox3 才能加载它.(OpenSSL 生成一个 PKCS#8 密钥).使用 RSAPublicKey 关键字.

In my experience, LockBox 3 needs a PKCS#1 public key when working with OpenSSL generated keys.You must convert the public key to PKCS#1 before Lockbox3 can load it. (OpenSSL generates a PKCS#8 key). Use the RSAPublicKey keyword.

openssl rsa -pubin -in yourpublickey -RSAPublicKey_out -out publicpkcs1
