Generate NFe Key

Navigation
2

I have closed source software that validates the NFe key in the invoice entry for the stock module.

I need to generate some NFe keys for testing.

So far, I know that the NFe key validates the provider's IBGE code, document number, and Note Series.

Does anyone have the algorithm for generating these invoice keys?

I need the algorithm to make a system for generating these keys.

I searched the internet but did not find this information, maybe looking wrong.

Can you help me?

Thank you.

The NFe key has the following rule: 

   cUF - Código da UF do emitente do Documento Fiscal;
    AAMM - Ano e Mês de emissão da NF-e;
    CNPJ - CNPJ do emitente;
    mod - Modelo do Documento Fiscal;
    serie - Série do Documento Fiscal;
    nNF - Número do Documento Fiscal;
    tpEmis – forma de emissão da NF-e;
    cNF - Código Numérico que compõe a Chave de Acesso;
    cDV - Dígito Verificador da Chave de Acesso.
