installing charm using conda not able to get packages

Question

I am trying to install charm-crypto package using conda. But, it gives me the following error:

Collecting package metadata: done Solving environment: failed

PackagesNotFoundError: The following packages are not available from current channels:

• charm

Current channels:

• https://conda.anaconda.org/r/win-64
• https://conda.anaconda.org/r/noarch
• https://repo.anaconda.com/pkgs/main/win-64
• https://repo.anaconda.com/pkgs/main/noarch
• https://repo.anaconda.com/pkgs/free/win-64 ...

To search for alternate channels that may provide the conda package you're looking for, navigate to

https://anaconda.org

and use the search bar at the top of the page.

From which site can I get the charm-crypto package?

Thanks in advance.
