# Breaking: #69916 - Removed BackendLogin::getRsaPublicKey AJAX handler

See [forge#69916](https://forge.typo3.org/issues/69916)

## Description

The deprecated AJAX handler `BackendLogin::getRsaPublicKey` has been removed in favor of `rsa_publickey`. As
`getRsaPublicKey` was the only method in this class, the file
`typo3/sysext/rsaauth/Classes/Backend/AjaxLoginHandler.php` has been removed without substitution.

## Impact

Calling the removed handler will result in an error.

## Affected Installations

All 3rd party extensions using the removed handler are affected.

## Migration

Use the AJAX handler `rsa_publickey` instead of `BackendLogin::getRsaPublicKey`.
