signify with -C

[jmccue]

I am having an issue with how to use signify(1) on all files in a Directory. Some files could be quite large and based upon my searches and manuals, this shows the issue:

1. To sign the files I do the following:

$ sha256 * > SHA256
$ signify -S -s my.sec -m SHA256

2. This is where the issue occurs:

$ signify -C -p my.pub -x SHA256.sig
signify: signature verification failed

3. But this works.

$ signify -V -p my.pub -m SHA256
Signature Verified

$ sha256 -c SHA256
lots of OKs

Is there something I am missing in step 2 ? Or are we suppose to use the method in step 3 ? Or is the issue with #1 ? Based upon what I read # 2 should work.

Thanks
