 ## Why sshutil?
 
-The sshutil package depends solely on the Go `x/crypto` library.
-Go's x/crypto/ssh package provides convenient support for both the [ssh wire protocol][rfc4253] and the [ssh authentication protocol][rfc4252].
+The sshutil package depends solely on the Go [`x/crypto`][crypto] module.
+Go's [`x/crypto/ssh`][crypto-ssh] package provides convenient support for both the [ssh wire protocol][rfc4253] and the [ssh authentication protocol][rfc4252].
 The authentication protocol implementation is scoped to single connections.
 A small, but tedious, amount of work is required to implement a full connection-tracking server.
 `sshutil` fills in the gap.
