When storing a binary blob of data in keychain for security reasons, what is considered a "big" blob of data? 1kB? 1MB? How big a blob of binary data can you store in keychain (without running into performance issues and whatnot).

The maximum length of your keychain string can be somewhere between 4 to 4.5 billion characters. You most likely aren't going to need to worry about this.

    Where did you get the 4Gig number from? Empirical testing shows the value to be much less (in the 16Meg range.) – Olie Nov 02 '15 at 21:07
