/*
* IMPORTANT NOTE
*
* The NIST test vector set includes several calls to
* HMAC_DRBG_Generate() that are expected to fail with a
* status of "Reseed required". The pattern seems to be that
* when prediction resistance is requested, any call to
* HMAC_DRBG_Generate() is at first expected to fail. After
* an explicit reseeding, the call to HMAC_DRBG_Generate() is
* retried, and on this second time it is expected to succeed.
*
* This pattern does not match the specifications for
* HMAC_DRBG_Generate(): neither HMAC_DRBG_Generate_algorithm
* (defined in ANS X9.82 Part 3-2007 Section 10.2.2.2.5 (NIST
* SP 800-90 Section 10.1.2.5)) nor the higher-level wrapper
* Generate_function defined in ANS X9.82 Part 3-2007 Section
* 9.4 (NIST SP 800-90 Section 9.3)) can possibly exhibit this
* behaviour:
*
* a) HMAC_DRBG_Generate_algorithm can return a "reseed
* required" status only as a result of the test
*
* "1. If reseed_counter > reseed_interval, then return
* an indication that a reseed is required."
*
* Since the reseed interval is independent of any request
* for prediction resistance, and since the reseed interval
* is not specified as part of the NIST test vector set,
* then this cannot be the source of the "Reseed required"
* failure expected by the NIST test vector set.
*
* b) Generate_function cannot return a "reseed required"
* status under any circumstances. If the underlying
* HMAC_DRBG_Generate_algorithm call returns "reseed
* required", then Generate_function will automatically
* reseed and try again.
*
* To produce the behaviour expected by the NIST test vector
* set, we therefore contrive to produce a "reseed required"
* state where necessary by setting the reseed_counter to
* greater than the reseed_interval.
