x509tools 
import "toolman.org/crypto/x509tools"
This package contains several x509-related helper functions not found in the standard library (albeit, perhaps they should be).
A non-trivial portion of this logic was take directly from the unexported side of the standard library's "crypto/x509" package -- therefore this package maintains the same copyright and license as the Go source code itself.
See the "LICENSE" file for more information.
