Este código usa a classe `SecretKeyFactory` para gerar um hash de senha usando o algoritmo PBKDF2 com HMAC-SHA256. O hash é gerado a partir de uma senha e um salt aleatório. O número de iterações e o comprimento da chave são definidos como 65536 e 256, respectivamente. O hash resultante é codificado em Base64 e impresso na tela.

Espero que isso ajude! Se você tiver alguma dúvida, por favor, não hesite em perguntar.

    Change the Storage Location for Docker Desktop with WSL2

Docker Desktop stores docker data in 2 distros

docker-desktop
docker-desktop-data

These distros are installed on the system drive by default.
To move them to another drive, these distros can be exported, deleted and imported from the new location.

                Running 'crc' on a remote server
              
          
    Overview: running crc on a remote server

This document shows how to deploy an OpenShift instance on a server using CodeReady Containers (crc) that can be accessed remotely from one or more client machines (sometimes called a "headless" instance). This provides a low-cost test and development platform that can be shared by developers. Deploying this way also allows a user to create an instance that uses more cpu and memory resources than may be available on his or her laptop.
While there are benefits to this type of deployment, please note that the primary use case for crc is to deploy a local OpenShift instance on a workstation or laptop and access it directly from the same machine. The headless setup is configured completely outside of crc itself, and supporting a headless setup is beyond the mission of the crc development team. Please do not ask for changes to crc to support this type of deployment, it will only cost the team time as they politely decline :)
The instructions here were tested with F
