Re: Changing Password Schemes

That's not SHA512-CRYPT. That's just a simple sha512 of the password, without salt.

A SHA512-CRYPT password will be generated with:

printf "1234\n1234" | doveadm pw -s SHA512-CRYPT

or:

doveadm pw -s SHA512-CRYPT -p 1234

or:

mkpasswd -m sha-512 1234

(without the "{SHA512-CRYPT}" prefix)

What exactly is the difficulty you are having with converting the passwords? What database engine are you using?

Looks like an SQL update would do this: UPDATE users SET passwd_SHA512 = SHA2(passwd_clear, 512);
