使用Signtool /ds签名时出现Error 0x80090027错误求助
SignTool /ds签名时出现0x80090027错误的问题分析
问题描述
使用/ds命令签名摘要文件时出现以下错误:
Done Adding Additional Store SignTool Error: SignedCode::Sign returned error: 0x80090027 The parameter is incorrect. SignTool Error: An error occurred while attempting to sign: .\installer.exe.dig Number of errors: 1
复现步骤
通过OpenSSL生成两层ECC secp256r1证书结构:
- 根CA证书
- 由根CA签名的代码签名证书(密钥用途为数字签名,增强型密钥用途为代码签名)
证书导出为.crt格式,完整链导出为.p12格式。执行以下步骤签名可执行文件:
- 移除原有签名:
signtool remove /s .\installer.exe
- 生成待签名的摘要文件:
signtool sign /fd SHA256 /f .\code_signing.crt /dg . .\installer.exe
- 签名摘要文件:
signtool sign /f .\code_signing_chain.p12 /p 1234 /fd SHA256 /ds .\installer.exe.dig
预期行为
成功签署摘要文件,生成可导入至.exe的.dig.signed文件。
实际行为
执行步骤3时出现上述错误,完整调试输出:
The following certificates were considered: Issued to: Code Signing Issued by: Root CA Expires: Fri Jun 12 13:40:55 2026 SHA1 hash: 23CDFBE9A6E02BB9419881EDBA5DFA9A81A02D2D Issued to: Root CA Issued by: Root CA Expires: Wed Jun 12 13:16:07 2030 SHA1 hash: 0C26C9CBE859B470A3D6A6D571A7619C94C496EC After EKU filter, 2 certs were left.

SignTool Error: An error occurred while attempting to sign: .\installer.exe.dig Number of files successfully Signed: 0 Number of warnings: 0 Number of errors: 1
额外上下文
使用Microsoft SDK 10.0A
问题根源及修复
问题出在步骤2:生成摘要时错误指定了无密钥的证书
/dg参数的作用是生成待签名的摘要文件,这一步不需要指定签名证书(/f参数)——因为生成摘要仅需计算文件哈希,不需要关联公钥或私钥。
你在步骤2中使用了/f .\code_signing.crt,而该文件仅包含公钥(无对应私钥),这会导致SignTool生成的.dig文件包含错误的元数据,最终在步骤3签名时触发0x80090027参数错误。
修复步骤
修改步骤2的命令,移除多余的/f参数:
signtool sign /fd SHA256 /dg . .\installer.exe
额外优化:步骤1的命令修正
signtool remove命令中/s参数用于指定系统证书存储,若要移除文件中的签名,正确用法应为:
signtool remove .\installer.exe
