Is there a way in PHP 5.3 to get crypt() blowfish (salt starting with $2a$) results identical to those generated by PHP 5.2? In 5.3, Zend implements all encryption algorithms internally, thus producing different results. Also, in 5.3, blowfish needs a cost parameter.
Basically, is there a way to call whatever system mechanisms were used for encryption in PHP 5.2 using a command line program?
Note: The server is on Linux, must be distro portable.
The internal implementations are supposed to be completely compatible with the external OS implementations.
Presumably the OS implementation (libxcrypt?) has a default value for the cost parameter if none is supplied – you’ll just have to track down what that is!
