+### Version number
+* 1: Dispersy
+* 2: py-ipv8
+
+### Master Peer Mid
+SHA1 hash of the public key
+
+### Message ID
+A message ID which determines which community and of what type the message is.
+
+Basically to determine to whom to pass the decoded packet.
+
+### Payloads
+The first
+
+
+### Trailer
+The trailer almost always consist of a signature signing the packet
+
+# Deserializing a packet
+1. Header
+2. Verify
+3. Rest
+
+## Header
+//TODO: Implement
+
+## Verify (OpenSSL)
+1. Get the Public key from the BinKey payload
+2. Parse it into a proper key (add pem header/trailer and give to to openssl)
+3. Find out its algorithm and curve
+4. Use the algo/curve to determine the length of the signature
+5. Extract the ECDSA signature to `r`,`s`
+6. Parse `r`,`s` into an `EcdsaSig`
+7. Verify the signature with the public key
+
+## Verify (libnacl-ed25519)
+1. Get the public key from the BinKey payload (detectable by the `libnacl` prefix)
+2. Parse into ed25519 public key
+3. extract the signature from the end (length is known)
+4. Verify the signature with the key
+
+## The rest
+The rest is handled by the correct community
+
+(No communities exist in our implmentation yet)
+
+
+# Serializing a packet
+
+## Header
+//TODO: Implement
+
+## Signing (OpenSSL)
+1. Get the private key from the user.
+2. Use the algorithm and corresponding curve of the key to calculate the signature (r,s) and needed padding.
+3. Return a Signature
+
+## Signing (libnacl-ed25519)
+1. Use the users private key to generate a signature over the given packet.
+2. Append the signature.
