phpass portable hashes The portable hashes are very simple, which was key to phpass' acceptance. More elaborate "portable hashes" would likely not be accepted; this may be something to try for a next generation phpass now that the foot is in the door. $P$Blongsalt3aidu9JAoAsLRML86yQuD0 In this example, "B" means 213 or 8192 iterations. The salt is 48-bit. phpBB3 uses 2048 iterations, WordPress uses 8192 (but these hashes are compatible with each other). Drupal 7 uses a revision of these hashes with MD5 replaced by SHA-512, the prefix changed to "$S$", and iteration counts at 16384 and beyond (increasing between releases).
