Is it possible to verify keys using kobs-ng?

I concatenated the first 4 fuse words of the fuse bank (not sure what is expected here):

root@imx6ull14x14evk:~# kobs-ng  imgverify -v -kF315B19099EF27C626B10686ABDD61DC  u-boot-nand-signed.imx
u-boot-nand-signed.imx: verifying using key 'f315b19099ef27c626b10686abdd61dc'
u-boot-nand-signed.imx: is a valid bootstream for key 'f315b19099ef27c626b10686abdd61dc'

 

I add one to the key, and it still works:

root@imx6ull14x14evk:~# kobs-ng  imgverify -v -kF315B19099EF27C626B10686ABDD61DD  u-boot-nand-signed.imx                                 
u-boot-nand-signed.imx: verifying using key 'f315b19099ef27c626b10686abdd61dd'
u-boot-nand-signed.imx: is a valid bootstream for key 'f315b19099ef27c626b10686abdd61dd'

Hello,

   What kobs-ng release is used in the case?

Is it possible to try the recent one?
