Data Structures
Here are the data structures with brief descriptions:

srtp_auth_t |
srtp_auth_test_case_t |
srtp_auth_type_t |
srtp_cipher_t |
srtp_cipher_test_case_t |
srtp_cipher_type_t |
srtp_crypto_policy_t | Srtp_crypto_policy_t describes a particular crypto policy that can be applied to an SRTP stream
srtp_debug_module_t |
srtp_event_data_t | Srtp_event_data_t is the structure passed as a callback to the event handler function
srtp_master_key_t | Srtp_master_key_t represents a master key. There will be a Master Key Index and the Master Key associated with the Master Key Index. Need to also keep track of the Master Key Index Size to correctly read it from a packet
srtp_policy_t | Policy for an SRTP session
srtp_ssrc_t | An srtp_ssrc_t represents a particular SSRC value, or a `wildcard' SSRC
