41  * of data. The average length of back to back _encryptBlock() calls with a fixed P-array is
42  * 514.12, which is ~4KB of data. Creating an eval()-optimized _encryptBlock() has an upfront
44  * data. Conseqeuently, bcrypt does not benefit from the eval()-optimized _encryptBlock().
66  * Every bcrypt round is the equivalent of encrypting 512KB of data. Since OpenSSH uses 16
67  * rounds by default that's ~8MB of data that's essentially being encrypted whenever
68  * you use bcrypt. That's a lot of data, however, bcrypt operates within tighter constraints
