I am learning about the Signal protocol and eventually hope on implementing it in one of my projects. I haven't been able to find the length of:
- Identity key IK
- Signed prekey SPK
- Prekey signature Sig(IK, Encode(SPK)) -One-time prekeys (OPK1, OPK2, OPK3, ...)
Does anyone know how many bits or bytes each key is?
