验证文件数字签名是否有效可以使用函数 WinVerifyTrust,
可以用:
取得文件数字签名证书信息需要使用函数 CryptQueryObject,再用CertFindCertificateInStore获取证书Cert
技术分享图片
也可以通过,WTHelperProvDataFromStateData WTHelperGetProvSignerFromChain WTHelperGetProvCertFromChain获取证书Cert

这里算法是:

typedef struct _CERT_INFO {
    DWORD                       dwVersion;
    CRYPT_INTEGER_BLOB          SerialNumber;
    CRYPT_ALGORITHM_IDENTIFIER  SignatureAlgorithm;
    CERT_NAME_BLOB              Issuer;
    FILETIME                    NotBefore;
    FILETIME                    NotAfter;
    CERT_NAME_BLOB              Subject;
    CERT_PUBLIC_KEY_INFO        SubjectPublicKeyInfo;
    CRYPT_BIT_BLOB              IssuerUniqueId;
    CRYPT_BIT_BLOB              SubjectUniqueId;
    DWORD                       cExtension;
    PCERT_EXTENSION             rgExtension;
} CERT_INFO, *PCERT_INFO;

CERT_INFO结构体中SignatureAlgorithm字段 同时这个字段也是一个结构体

typedef struct _CRYPT_ALGORITHM_IDENTIFIER {
    LPSTR               pszObjId;
    CRYPT_OBJID_BLOB    Parameters;
} CRYPT_ALGORITHM_IDENTIFIER, *PCRYPT_ALGORITHM_IDENTIFIER;

CRYPT_ALGORITHM_IDENTIFIER第一个字段就是对应算法,但是值是一个字符串 要通过宏查看 得自己转换
宏有:
