1) bcrypt uses salts so that won't work at all 2) if you use some other computationally expensive hash you run into the problem of low powered mobile hardware.

2) if you use some other computationally expensive hash you run into the problem of low powered mobile hardware. Remember you're not hashing 1 thing, but dozens or hundreds of phone numbers or email addresses.
- chubs 15y agoYou know, i think you're right - if we use different salts for each emails/phones, there'd be no way of ensuring that different users use the same salts, or even if we stored the salt along with the hash, it wouldn't be much use. Hmm this is a tricky problem!
