    node-signtool is a Node module wrapper around the SignTool binary.

    Getting Started

    node-signtool works as a wrapper around the SignTool library. It abstracts the commands' switches with JS object abstraction. Options mapping is available below.


    node-signtool can be installed using NPM:

    $ npm install node-signtool --save


    First import node-signtool in your project:

    var signtool = require("signtool");

    Then use signtool's commands:

    signtool.sign("path/to/my.exe", { certificate: "path/to/my/cert.pfx", password: "*******" });

    node-signtool uses native Promise to wrap asynchronous operations and resolves with the result of the command:

    signtool.sign("path/to/my.exe", { certificate: "path/to/my/cert.pfx", password: "*******" });
        .then(result => {
            result.code  // The signtool exit code.
            result.stdout  // The signtool stdout content.
            result.stderr // The signtool stderr content.


    signtool.sign(file: string | string[], [options: SignOptions], [runOptions: RunOptions]): Promise

    The sign command allows to digitally signs files. If no options are provided, node-signtool use the default auto behavior.

    Switch Option Description
    /a auto Selects the best signing certificate automatically.
    /as append Appends this signature. If no primary signature is present, this signature is made the primary signature.
    /uw verify Specifies using "Windows System Component Verification" (
    /f certificate Specifies the signing certificate in a file (PFX).
    /p password Specifies the password to use when opening a PFX file.
    /i issuer Specifies the name of the issuer of the signing certificate.
    /n subject Specifies the name of the subject of the signing certificate.
    /r rootSubject Specifies the name of the subject of the root certificate that the signing certificate must chain to.
    /d description Specifies a description of the signed content.
    /du url Specifies a URL for expanded description of the signed content.
    /s store Specifies the store to open when searching for the certificate.
    /sm computerStore Specifies that a computer store, instead of a user store, be used.
    /sha1 sha1 Specifies the SHA1 hash of the signing certificate.
    /csp csp Specifies the cryptographic service provider (CSP) that contains the private key container.
    /kc key Specifies the key that contains the name of the private key.
    /c template Specifies the Certificate Template Name (a Microsoft extension) for the signing certificate.
    /ac additional Specifies a file that contains an additional certificate to add to the signature block.
    /fd algorithm Specifies the file digest algorithm to use to create file signatures.
    /u EKU Specifies the enhanced key usage (EKU) that must be present in the signing certificate.
    /t timestamp Specifies the URL of the time stamp server.
    /tr rfcTimestamp Specifies the RFC 3161 time stamp server's URL.
    /td timestampAlgo Used with the rfcTimestamp switch to request a digest algorithm used by the RFC 3161 time stamp server.
    /dg digest Generates the to be signed digest and the unsigned PKCS7 files.
    /dxml digestXML When used with the digest option, produces an XML file.
    /dmdf digestFunction When used with the digest option, passes the file’s contents to the AuthenticodeDigestSign function without modification.
    /dlib digestLib Specifies the DLL implementing the AuthenticodeDigestSign function.
    /ds digestOnly Signs the digest only. The input file should be the digest generated by the digest option.
    /p7 pkcs Creates the signature by ingesting the signed digest to the unsigned PKCS7 file.
    /p7ce pkcsCE Specifies options for the signed PKCS #7 content.
    /p7co pkcsOID Specifies the object identifier (OID) that identifies the signed PKCS #7 content.
    /ph pageHashes If supported, generates page hashes for executable files.
    /nph suppresPageHashes If supported, suppresses page hashes for executable files.

    signtool.verify(file: string | string[], [options: VerifyOptions], [runOptions: RunOptions]): Promise

    The verify command allows to verify the digital signature of files.

    If no options are provided, node-signtool use the default useAllMethods behavior.

    The SignTool verify command determines :

    • whether the signing certificate was issued by a trusted authority,
    • whether the signing certificate has been revoked,
    • and, optionally, whether the signing certificate is valid for a specific policy.
    Switch Option Description
    /a useAllMethods Specifies that all methods can be used to verify the file.
    /o os Verifies the file by operating system version. (PlatformID:VerMajor.VerMinor.BuildNumber)
    /ds index Verifies the signature at a certain position.
    /hash hash Specifies an optional hash algorithm to use when searching for a file in a catalog.
    /r rootSubject Specifies the name of the subject of the root certificate that the signing certificate must chain to.
    /ag catalogDatabase Finds the catalog in the catalog database identified by the GUID.
    /c useDefaultCatalog Specifies the catalog file by name.
    /ad useDefaultCatalog Finds the catalog by using the default catalog database.
    /as useDriverCatalog Finds the catalog by using the system component (driver) catalog database.
    /all verifyAllSignatures Verifies all signatures in a file with multiple signatures.
    /kp useX64Kernel Performs the verification by using the x64 kernel-mode driver signing policy.
    /ms useMultiSemantics Uses multiple verification semantics.
    /p7 verifyPKCS Verify PKCS #7 files.
    /ph verifyPageHash Print and verify page hash values.
    /tw verifyTimestamp Specifies that a warning is generated if the signature is not time stamped.
    /pa defaultAuthPolicy Specifies that the Default Authentication Verification Policy is used.
    /pg useAuthPolicy Specifies a verification policy by GUID.
    /d showDescription Print the description and description URL.

    signtool.timestamp(file: string | string[], [options: TimestampOptions], [runOptions: RunOptions]): Promise

    The timestamp command allows to time stamps files.

    Switch Option Description
    /t url The file being time stamped must have previously been signed.
    /tr rfcUrl Specifies the RFC 3161 time stamp server's URL.
    /tseal sealUrl Specifies the RFC 3161 timestamp server's URL for timestamping a Sealed file.
    /td algorithm Used with the rfcUrl switch to request a digest algorithm used by the RFC 3161 time stamp server.
    /tp index Adds a timestamp to the signature at index.
    /p7 pkcs Adds a timestamp to PKCS #7 files.

    signtool.catdb(file: string | string[], [options: CatDBOptions], [runOptions: RunOptions]): Promise

    The catdb command allows to add or remove a catalog file to or from a catalog database.

    Switch Option Description
    /d default Specifies that the default catalog database be updated.
    /g guid Specifies that the catalog database identified by the GUID be updated.
    /r remove Removes the specified catalog from the catalog database.
    /u unique Specifies that a unique name be automatically generated for the added catalog files.


    Run options are optional. It allows to enable some common signtool switches and to specify some child_process.spawn() options.

    Common Switches
    Switch Option Description
    /q quiet No output on success and minimal output on failure.
    /v verbose Print verbose success and status messages.
    /debug debug Display additional debug information.
    Spawn Options
    Spawn Option Description
    cwd cwd Specifies the Current Working Directory to execute signtool on.
    stdio stdio Specifies the spawn stdio option.
