Name

dotnet nuget verify - Verifies a signed NuGet package.

Synopsis

dotnet nuget verify [<package-path(s)>]
    [--all]
    [--certificate-fingerprint <FINGERPRINT>]
    [-v|--verbosity <LEVEL>]
    [--configfile <FILE>]

dotnet nuget verify -h|--help

Description

The dotnet nuget verify command verifies a signed NuGet package.

Note

This command requires a certificate root store that is valid for both code signing and timestamping. Also, this command may not be supported on some combinations of operating system and .NET SDK. For more information, see NuGet signed package verification.

Arguments

  • package-path(s)

    Specifies the file path to the package(s) to be verified. Multiple position arguments can be passed in to verify multiple packages.

Options

  • --all

    Specifies that all verifications possible should be performed on the package(s). By default, only signatures are verified.

Note

This command currently supports only signature verification.

  • --certificate-fingerprint <FINGERPRINT>

    Verify that the signer certificate matches with one of the specified SHA256 fingerprints. This option can be supplied multiple times to provide multiple fingerprints.

  • -v|--verbosity <LEVEL>

    Sets the verbosity level of the command. Allowed values are q[uiet], m[inimal], n[ormal], d[etailed], and diag[nostic]. The default is minimal. For more information, see LoggerVerbosity.

    The following table shows what is displayed for each verbosity level.

  • --configfile <FILE>

    The NuGet configuration file (nuget.config) to use. If specified, only the settings from this file will be used. If not specified, the hierarchy of configuration files from the current directory will be used. For more information, see Common NuGet Configurations.

  • -?|-h|--help

    Prints out a description of how to use the command.

Examples

  • Verify foo.nupkg:

    dotnet nuget verify foo.nupkg

  • Verify multiple NuGet packages - foo.nupkg and all .nupkg files in the directory specified:

    dotnet nuget verify foo.nupkg c:\mydir\*.nupkg

  • Verify foo.nupkg signature matches with the specified certificate fingerprint:

    dotnet nuget verify foo.nupkg --certificate-fingerprint CE40881FF5F0AD3E58965DA20A9F571EF1651A56933748E1BF1C99E537C4E039

  • Verify foo.nupkg signature matches with one of the specified certificate fingerprints:

    dotnet nuget verify foo.nupkg --certificate-fingerprint CE40881FF5F0AD3E58965DA20A9F571EF1651A56933748E1BF1C99E537C4E039 --certificate-fingerprint EC10992GG5F0AD3E58965DA20A9F571EF1651A56933748E1BF1C99E537C4E027

  • Verify the signature of foo.nupkg by using settings (packagesources and trustedSigners) only from the specified nuget.config file:

    dotnet nuget verify foo.nupkg --configfile ..\Settings\nuget.config
