Comparing $2y$ hashes

[kevinhikaruevans]

I have some hashes in my database which were previously created with PHP's bcrypt function.

If I try to run bcrypt.compareSync with the PHP's $2y$ versioned hash, it errors with "Invalid salt revision". Would it be possible to support $2y$ hashes instead of just $2a$?

I'm having same issue with django. Django has $2b$ hashes. Any reason for that not to be supported?

Exactly the same error with PHP generated hashes. Using "bcrypt-nodejs": "^0.0.3".

Manipulate the PHP hash with the following

phphash = phphash.replace(/^\$2y(.+)$/i, '$2a$1');

Works for me. From https://stackoverflow.com/questions/23015043/verify-password-hash-in-nodejs-which-was-generated-in-php
