## Fully supported hashing methods

The most current mailcow fully supports the following hashing methods.
The default hashing method is written in bold:

- **BLF-CRYPT**
- SSHA
- SSHA256
- SSHA512

The methods above can be used in `mailcow.conf` as `MAILCOW_PASS_SCHEME` value.

## Read-only hashing methods

The following methods are supported **read only**. 

- MD5-CRYPT
- PLAIN-MD5
- SHA512-CRYPT

That means mailcow is able to verify users with a hash like `{PLAIN-MD5}1a1dc91c907325c69271ddf0c944bc72` from the database.

The value of `MAILCOW_PASS_SCHEME` will _always_ be used to encrypt new passwords.

A "view" needs to be updated. You can trigger this by restarting sogo-mailcow: `docker-compose restart sogo-mailcow`
