Description:

Content:

Classes:

• MIKEYDecryptInfo
• MIKEYEncryptInfo
• MIKEYMessage - Structure holding the information of the MIKEY message
• MIKEYPayload - Hold the common fields for all payloads
• MIKEYPayloadKEMAC - A structure holding the KEMAC payload
• MIKEYPayloadKeyData - The Key data payload contains key material.
• MIKEYPayloadPKE - The Envelope data payload contains the encrypted envelope key that is used in the public-key transport to protect the data in the Key data transport payload.
• MIKEYPayloadRAND - The RAND payload consists of a (pseudo-)random bit-string
• MIKEYPayloadSP - The Security Policy payload defines a set of policies that apply to a specific security protocol
• MIKEYPayloadT - The timestamp payload carries the timestamp information
• Message - The GstSDPMessage helper functions makes it easy to parse and create SDP messages.

Structs:

• Attribute - The contents of the SDP "a=" field which contains a key/value pair.
• Bandwidth - The contents of the SDP "b=" field which specifies the proposed bandwidth to be used by the session or media.
• Connection - The contents of the SDP "c=" field which contains connection data.
• Key - The contents of the SDP "k=" field which is used to convey encryption keys.
• MIKEYMapSRTP - The Security policy Map item for SRTP
• MIKEYPayloadSPParam - A Type/Length/Value field for security parameters
• Media - The contents of the SDP "m=" field with all related fields.
• Origin - The contents of the SDP "o=" field which gives the originator of the session (their username and the address of the user's host) plus a session id and session version number.
• Time - The contents of the SDP "t=" field which specify the start and stop times for a conference session.
• Zone - The contents of the SDP "z=" field which allows the sender to specify a list of time zone adjustments and offsets from the base time.

Enums:

• MIKEYCacheType - The different cache types
• MIKEYEncAlg - The encryption algorithm used to encrypt the Encr data field
• MIKEYKVType - The key validity type
• MIKEYKeyDataType - The type of key.
• MIKEYMacAlg - Specifies the authentication algorithm used
• MIKEYMapType - Specifies the method of uniquely mapping Crypto Sessions to the security protocol sessions.
• MIKEYPRFFunc - The PRF function that has been/will be used for key derivation
• MIKEYPayloadType - Different MIKEY Payload types.
• MIKEYSecProto - Specifies the security protocol
• MIKEYSecSRTP - This policy specifies the parameters for SRTP and SRTCP
• MIKEYTSType - Specifies the timestamp type.
• MIKEYType - Different MIKEY data types.
• Result - Return values for the SDP functions.
