 This is the java network library with support for SSL, standard cipher encryption (.net Compatible!), fragmentation, packet object and network stream support.
 
+This requires the [calmstdcrypt library](https://code.mrmelon54.xyz/alfred/calmstdcrypt), which is my cryptographic wrapper library.
+
 This library contains streams that can wrap both Socket and DatagramSocket objects.
 Sending large amounts over UDP is also do-able using the fragmentation part of the library.
