comment Derive a key from public data using a secret master key
@RickyDemer That's interesting to know. From an implementation perspective, I have reasons why my design is preferable to HKDF. If you would be willing to add an answer with some additional details it would be very helpful to me.

@CodesInChaos I've been told it's 64 bits, so that's comfortably smaller than 16 bytes.

comment Derive a key from public data using a secret master key
@CodesInChaos Sorry, I confused one RFC with another in my mind. My comments were probably more applicable to key derivation schemes such as those in PKCS #5.
