# Cryptography
|
|
|
|
The Nym Network relies on several cryptographic systems working together. This section covers the algorithms, packet formats, and credential systems that provide privacy guarantees.
|
|
|
|
## What's covered
|
|
|
|
[Sphinx Packets](/network/cryptography/sphinx) explains the packet format used for layered encryption and anonymous routing. Each Sphinx packet contains routing information encrypted in layers, where each hop can only decrypt its own layer.
|
|
|
|
[zk-nyms](/network/cryptography/zk-nym) covers the anonymous credential system that separates payment from usage. This is how you can pay for network access without that payment being linkable to your activity.
