Class SDPSecurityDescription

(SDP) Security Descriptions for Media Streams implementation as basically defined in RFC 4568.

Example 1: Parse crypto attribute

string crypto = "a=crypto:1 AES_256_CM_HMAC_SHA1_80 inline:GTuZoqOsesiK4wfyL7Rsq6uHHwhqVGA+aVuAUnsmWktYacZyJu6/6tUQeUti0Q==";
SDPSecurityDescription localcrypto = SDPSecurityDescription.Parse(crypto);
Example 2: Parse crypto attribute

SDPMediaAnnouncement mediaAudio = new SDPMediaAnnouncement();
//[...]set some SDPMediaAnnouncement properties
SDPSecurityDescription localcrypto = SDPSecurityDescription.CreateNew();
localcrypto.KeyParams.Clear();
localcrypto.KeyParams.Add(SDPSecurityDescription.KeyParameter.CreateNew(SDPSecurityDescription.CryptoSuites.AES_CM_128_HMAC_SHA1_32));
mediaAudio.SecurityDescriptions.Add(localcrypto);
mediaAudio.ToString();

string crypto = "a=crypto:1 AES_256_CM_HMAC_SHA1_80 inline:GTuZoqOsesiK4wfyL7Rsq6uHHwhqVGA+aVuAUnsmWktYacZyJu6/6tUQeUti0Q==";
SDPSecurityDescription desc = SDPSecurityDescription.Parse(crypto);
