Havia um OAuth 1, que é bem diferente do OAuth2, e mais complexo, isso incluía diretamente as especificações de como criptografar a comunicação.

Não é muito popular ou usado nos dias atuais.

OAuth2 não especifica como criptografar a comunicação, ele espera que você tenha sua aplicação em um servidor HTTPS.
