Method Documentation

createLongTermKeyWithUsername:realm:password:

+ (NSMutableData*) createLongTermKeyWithUsername:		(NSString *)	username
realm:		(NSString *)	realm
password:		(NSString *)	password

Creates a long term key from the given username, realm, and password by calculating the MD5 hash of their values concatenated as "username:realm:password".

    MD5 is required by RFC 5389 (STUN) and RFC 8656 (TURN) for long-term credential
    key derivation. This is a protocol requirement for interoperability with standard
    STUN/TURN clients and cannot be changed to a more secure hash without breaking
    compatibility. The security of the authentication mechanism relies on HMAC-SHA1
    over the derived key, not on MD5's collision resistance.

Parameters

username	The username.
realm	The realm.
password	The password.

createShortTermKeyWithPassword:

+ (NSMutableData*) createShortTermKeyWithPassword:

(NSString *)

password

Creates a short term key from the given password by encoding it as a UTF-8 byte array.

Parameters

password

The password.
