Scenario 1

Package 'SamplePackage v1.0.0' from source 'https://contoso.com/index.json': The timestamp signature has an unsupported digest algorithm. The following algorithms are supported: : SHA-2-256, SHA-2-384, SHA-2-512.

Issue

The timestamp's signature has an unsupported digest algorithm.

Solution

Ensure that the timestamp authority's signature has one of the following digest algorithms -

• SHA-2-256
• SHA-2-384
• SHA-2-512

Scenario 2

Package 'SamplePackage v1.0.0' from source 'https://contoso.com/index.json': The primary signature's timestamp signature has an unsupported digest algorithm.

Issue

The timestamp's signature has an unsupported digest algorithm.

Solution

Request the package author to re-sign the package using the nuget sign command as described in NuGet docs using the -Timestamper option such that the timestamp authority signing certificate has one of the following digest algorithms -

• SHA-2-256
• SHA-2-384
• SHA-2-512

Note

When running the nuget verify -signatures command, NU3024 is raised as an error. Otherwise, NU3024 is raised as a warning.
