Typedef Documentation

typedef struct srtpSecrets SrtpSecret_t

This structure contains pointers to the SRTP secrets and the role info.

About the role and what the meaning of the role is refer to the of the enum Role. The pointers to the secrets are valid as long as the ZRtp object is active. To use these data after the ZRtp object's lifetime you may copy the data into a save place. The destructor of ZRtp clears the data.

Enumeration Type Documentation

enum EnableSecurity

Enumerator
ForReceiver	Enable security for SRTP receiver.
ForSender	Enable security for SRTP sender.

Definition at line 99 of file ZrtpCallback.h.

enum Role

This enum defines which role a ZRTP peer has.

According to the ZRTP specification the role determines which keys to use to encrypt or decrypt SRTP data.

• The Initiator encrypts SRTP data using the keyInitiator and the saltInitiator data, the Responder uses these data to decrypt.
• The Responder encrypts SRTP data using the keyResponder and the saltResponder data, the Initiator uses these data to decrypt.

Enumerator
Responder	This client is in ZRTP Responder mode.
Initiator	This client is in ZRTP Initiator mode.

Definition at line 60 of file ZrtpCallback.h.

enum SrtpAlgorithms

The algorihms that we support in SRTP and that ZRTP can negotiate.

Enumerator
None
Aes	Use AES as symmetrical cipher algorithm.
TwoFish	Use TwoFish as symmetrical cipher algorithm.
Sha1	Use Sha1 as authentication algorithm.
Skein	Use Skein as authentication algorithm.
