MODERATORS
Hashing is completely irreversible. You cannot hash an email address and then unhash it. At most you can brute-force guess the email until the hash matches, but this is basically impossible.
Hashing the email address would break one of the main reasons to use an email address - the ability to send emails to users.
Encrypting email addresses is fine, but you wouldnt compare the encrypted data, you'd just decrypt and compare the original email address.
Man, youre totally right and I now feel embarassed i forgot that.
