This is useful as npm-lockdown uses sha1 because npm releases the sha1 of packages and whilst this is undocumented it seems no other algorithm is supported (Bitbake rev: fd5d9011f6dd7029895b64d8a02d33185b9aa8ae) Signed-off-by: Brendan Le Foll <brendan.le.foll@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
