I used to run my mail server's DB in MariaDB (10.5.16) on-prem on Debian 10. I've now migrated this to RDS, however I would also like to try and migrate to DynamoDB. Most of the data is plaintext, however per say in my account table I have my passwords as encrypted SHA512-CRYPT strings.
What should I do to properly and securely migrate this to DynamoDB? I believe the encryption/decryption of the passwords used to happen on the local machine using openssl rather the database engine? That being said if I am to simply migrate these encrypted SHA512 strings into DynamoDB attributes, they won't be translated to plaintext data when called, yes?
I'm pretty bad with DBA stuff and this is for my personal mail server.. Would appreciate any help for the right direction.
Thanks!
