Description: PGP—Pretty Good Privacy，是一个基于RSA公匙加密体系的邮件加密软件。可以用它对你的邮件保密以防止非授权者阅读，它还能对你的邮件加上数字签名从而使收信人可以确信邮件是你发来的。它让你可以安全地和你从未见过的人们通讯，事先并不需要任何保密的渠道用来传递密匙。它采用了：审慎的密匙管理，一种RSA和传统加密的杂合算法，用于数字签名的邮件文摘算法，加密前压缩等，还有一个良好的人机工程设计。它的功能强大，有很快的速度。-PGP-Pretty Good Privacy, is a based on the RSA public key encryption system for e-mail encryption software. Can use its e-mail your confidential to prevent unauthorized persons to read, it can add to your e-mail digital signature so that the recipient can be sure that your message is sent. It lets you safely and you have never seen people in communications, in advance does not require any of the channels used to transmit confidential key. It uses the: key to prudent management, an RSA encryption and traditional hybrid algorithm for digital signatures, message digest algorithm, encryption before compression, as well as a good ergonomic design. Its powerful, has quickly speed. Platform: |

Description: 开始，运行输入 sigverif
通过检查数字签名就知道是不是ms的了。
主要使用Win32API实现验证应用或驱动程
WinVerifyTrust API。如果该API被Hook有没有其他方法验证应用或驱动程序是否通过微软签名？如果仅仅是被挂钩了IAT，那么可以直接通过函数指针调用。
如果是像Detours那样用jmp改写了函数头，可以通过读取WinTrust.dll中WinVerifyTrust的实现位置，恢复函数头的机器码。
不知道使用CryptoAPI，再使用指定的Microsoft证书
是不是更好一点，不容易被欺骗
怕调api被hook的话，自己将验证的代码写出来，用openssl应该容易点。-Start, Run enter sigverif by checking the digital signature is not on the know of the ms. Win32API realize the main use of the application or driver to verify WinVerifyTrust API. If the API was Hook has no other way to verify whether the application or driver through Microsoft Signed? If merely being linked to the IAT, you can call directly through the function pointer. If it is used as the Detours as to alter the function jmp head, can be read in WinVerifyTrust Wintrust.dll realize the location, the restoration of function of the binary header. Do not know the use of CryptoAPI, and then use the specified certificate is not Microsoft a little better, not easy to be deceived by fear api tune hook, then he would write the code to verify, using openssl should be easy points.

Description: Digital Signature Algorithm (DSA)是Schnorr和ElGamal签名算法的变种，被美国NIST作为DSS(DigitalSignature Standard)。算法中应用了下述参数：
p：L bits长的素数。L是64的倍数，范围是512到1024；
q：p - 1的160bits的素因子；
g：g = h^((p-1)/q) mod p，h满足h < p - 1, h^((p-1)/q) mod p > 1；
x：x < q，x为私钥 ；
y：y = g^x mod p ，( p, q, g, y )为公钥；
H( x )：One-Way Hash函数。DSS中选用SHA( Secure Hash Algorithm )。
p, q, g可由一组用户共享，但在实际应用中，使用公共模数可能会带来一定的威胁。签名及验证协议如下：
1. P产生随机数k，k < q；
2. P计算 r = ( g^k mod p ) mod q
s = ( k^(-1) (H(m) + xr)) mod q
签名结果是( m, r, s )。
3. 验证时计算 w = s^(-1)mod q
u1 = ( H( m ) * w ) mod q
u2 = ( r * w ) mod q
v = (( g^u1 * y^u2 ) mod p ) mod q
若v = r，则认为签名有效。
DSA是基于整数有限域离散对数难题的，其安全性与RSA相比差不多。DSA的一个重要特点是两个素数公开，这样，当使用别人的p和q时，即使不知道私钥，你也能确认它们是否是随机产生的，还是作了手脚。RSA算法却作不到。
