* 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 (i.e.) 512 bits of key material for use as two 256 bit keys, an
|
||||
* attacker can merely run once through the outer loop below, 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.
