Signify ported from OpenBSD to Linux
=====================================
with these differences:
* Randomness is provided by syscall 'getrandom' (Linux ≥3.18)
* or RDRAND.
* Compiles to a static binary of less than 180KiB (less than 270KiB with *Seccomp* and *musl-libc*).
The resulting binary is licensed under the same terms as OpenBSD's *signify*.
For the sources — please see the source files for their licensing terms,
and if you are permitted to use them in another work.
Usage
------
```bash
# generate a keypair
$ signify -G -c "Your Name " -p mark.pub -s mark.sec
# sign (usually a small file, like the output of: sha512sum …) "TheFileName"
$ signify -S -x TheFileName.sig -s mark.sec -m TheFileName
# verify
$ signify -V -x TheFileName.sig -p mark.pub -m TheFileName
Signature Verified
```
Or shorthand for if `TheFileName` and a similarly named `TheFileName.sig` exist:
```bash
$ signify -V -p mark.pub -m TheFileName
Signature Verified
```
