_esp_srp_gen_salt_verifier() function

free esp_srp_context

Set the Salt and Verifier pre-generated for a given password. This should be used only if the actual password is not available. The public key can then be generated using esp_srp_srv_pubkey_from_salt_verifier() and not esp_srp_srv_pubkey()

Returns B (pub key)[Step2.b] when the salt and verifier are set using esp_srp_set_salt_verifier()

Get session key in `*bytes_key` given by len in `*len_key`. [Step2.c]. This calculated session key is used for further communication given the proofs are exchanged/authenticated with `esp_srp_exchange_proofs`

Complete the authentication. If this step fails, the session_key exchanged should not be used This is the final authentication step in SRP algorithm [Step4.1, Step4.b, Step4.c]

Returns B (pub key) and salt. [Step2.b]
