I find acerto meaning hit, but in this case does acerto mean to get a copy of keys, reprogramming keys, or anything else?

    Do you have a context to that expression?

Check meaning 4. from Aulete:

4. Mec. Regulagem de máquina, motor etc., para que funcione perfeitamente.

Acerto could indeed be a form of the verb acertar (indicative, present, first person, singular), but not here. In that case, it would be pronounced with an open e, rather than the closed one of the noun acerto.

    I think the answer would be stronger if it showed the concrete meaning of the whole expression.

  • I agree that meaning 4 is the most relevant among those in Aulete, but I still don't understand what «acerto eletrónico de chaves» means. Then there's the side issue of acerto as hit. Acerto is the act of acertar. But even though one of the meanings of acertar is to hit, we don't use acerto to mean the act of hitting, only the act of acertar in its other meanings. I think the OP was referring to the possibility of acerto meaning the act of hitting, not (eu) acerto.

    @Jacinto I don't see any reason to think the OP thought that acerto meant hit (noun) due to it generally being the act of acertar. That requires quite a bit more sophisticated thought when compared to the OP just having been exposed to acerto as a verb. As to what acerto eletrónico de chaves means we can only guess (the OP gave no context, for instance we don't know whether the keys themselves are electronic), and therefore I did not expand on that.

    Acerto is a noun in «acerto eletrónico de chaves». That's why I think the OP means a noun in «I find acerto meaning hit». Google will (poorly) translate it as a noun too. But @ANeves, you appear to know what that «acerto eletrónico de chaves» is.

Acerto eletronico de chaves seems to be the translation from the english term key establishment used in computer communications. When 2 or more computers want to exchange data in a secure way, they first have to agree on a common key to be used in a cryptographic protocol. This may sound as a paradox, but there are ways to exchange secrets over a public communications channel.

As soon as the communicating computers agree on a key to use on a secure protocol, they have an acerto eletronico de chaves. Thus the most appropriate meaning from acerto as from Aulete is number 2:

2. Aquilo que se combinou; ACORDO; COMBINAÇÃO
  • Não o chegaste a afirmar que acerto eletrónico de chaves é correntemente usado com esse significado. É?

  • @Jacinto, Normalmente eu leio outras expressões tais como acordo de chaves ou estabelecimento de chaves. Não recordo ter lido acerto de chaves. Mesmo assim creio que o sentido seja o que descrevi acima. Talvez um pouco mais de contexto por parte do OP possa ser útil.

  • Eu também acho a tua interpretação plausível, mas de facto sem mais contexto não é possível ter certezas. Perguntei porque fiquei na dúvida se não tinhas sido definitivo por desatenção ou reserva.
