comment Generating an IV for ESP 3DES-CBC
@JuanAndrés: with the first option, using a fixed (known) IV to kick the process is just fine, because you won't be actually transmitting it. Instead, it's just part of the formula for creating the IV you will actually be sending.

comment Do ciphertexts leak information about their algorithmic creators?
The other way the encryption algorithm is leaked is via the protocol. For example, TLS negotiates which ciphersuite it'll use in the clear; hence anyone listening can determine which cipher is (initially) being used, but not by a specific cryptographical weakness.
