+ * pkcs #5 pbkdf2 implementation using the "bcrypt" hash
+ *
+ * The bcrypt hash function is derived from the bcrypt password hashing
+ * function with the following modifications:
+ * 1. The input password and salt are preprocessed with SHA512.
+ * 2. The output length is expanded to 256 bits.
+ * 3. Subsequently the magic string to be encrypted is lengthened and modifed
+ * to "OxychromaticBlowfishSwatDynamite"
+ * 4. The hash function is defined to perform 64 rounds of initial state
+ * expansion. (More rounds are performed by iterating the hash.)
+ *
+ * Note that this implementation pulls the SHA512 operations into the caller
+ * as a performance optimization.
+ *
+ * One modification from official pbkdf2. Instead of outputting key material
+ * linearly, we mix it. pbkdf2 has a known weakness where if one uses it to
+ * generate (e.g.) 512 bits of key material for use as two 256 bit keys, an
+ * attacker can merely run once through the outer loop, but the user
+ * always runs it twice. Shuffling output bytes requires computing the
+ * entirety of the key material to assemble any subkey. This is something a
+ * wise caller could do; we just do it for you.
