Problem during users import in Firebase Authentication

[mashood...@gmail.com]

I have one important question about the import of users into firebase authentication. My old system contains users passwords in md5 hash format. I used php md5 function to take the hash of passwords. Now the problem is that while importing the user through firebase command line, firbase import command requires the number of rounds used during md5 hash, but php don't provide any information about that. As a result user password don't match after import. Kindly help me to get rid of that problem. I am waiting for your kind response.

Hi Tanveer,

We don't have any way to guess the number of rounds here, sorry. I'm pretty sure, though, that PHP's crypt() method uses 5000 rounds as the default, but that's a configurable setting, and I'm not sure it applies to MD5 anyway, as I think rounds are just used for SHA256 and SHA512. So it's possible this isn't even applicable.

☼, Kato
