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?
