# Deprecation: #84407 - AJAX request methods in RsaEncryptionEncoder {#deprecation-84407-ajax-request-methods-in-rsaencryptionencoder}

See [forge#84407](https://forge.typo3.org/issues/84407)

## Description {#description}

All methods related to AJAX requests in `\TYPO3\CMS\Rsaauth\RsaEncryptionEncoder` have been marked as deprecated:

-   `getRsaPublicKeyAjaxHandler()`

The `rsa_publickey` AJAX route has been adapted to use the
`\TYPO3\CMS\Rsaauth\Controller\RsaPublicKeyGenerationController` which was already used for RSA key retrieval via
eID in the frontend.

## Impact {#impact}

Calling the above method on an instance of `RsaEncryptionEncoder` will throw a deprecation warning in v9 and a
PHP fatal in v10.

## Affected Installations {#affected-installations}

All extensions that call the deprecated method are affected.

## Migration {#migration}

Extensions should use the AJAX route `rsa_publickey` instead of the deprecated method.
