 # sigtool/sign - Ed25519 signature calculation and verification
 
 This is a small library that makes it easier to create and serialize Ed25519 keys, and sign,
 verify files using those keys. The library uses mmap(2) to read and process very large files.
 
-The companion program [sigtool](https://git.rgst.io/homelab/sigtool/v3) uses this library.
