## Cryptographic Primitives ## Cryptographic Primitives
Reticulum uses a simple suite of efficient, strong and modern cryptographic Reticulum uses a simple suite of efficient, strong and well-tested cryptographic
primitives, with widely available implementations that can be used both on primitives, with widely available implementations that can be used both on
general-purpose CPUs and on microcontrollers. The necessary primitives are: general-purpose CPUs and on microcontrollers. The utilised primitives are:
- Ed25519 for signatures - Reticulum Identity Keys are 512-bit Curve25519 keysets
- X22519 for ECDH key exchanges - A 256-bit Ed25519 key for signatures
- A 256-bit X22519 key for ECDH key exchanges
- HKDF for key derivation - HKDF for key derivation
- Modified Fernet for encrypted tokens - Encrypted tokens are based on the [Fernet spec](https://github.com/fernet/spec/)
- Ephemeral keys derived from an ECDH key exchange on Curve25519 - Ephemeral keys derived from an ECDH key exchange on Curve25519
