Method Details

buildOCSPRequest

public static Optional<org.bouncycastle.cert.ocsp.OCSPReq> buildOCSPRequest(Object certificate,
 Object issuer)

Cria uma requisição para servidor OCSP

Parameters:

certificate - Certificado a ser validado

issuer - Certificado do emissor

Returns:

A requisição para servidor OCSP gerada

requestOCSPResponse

public static org.apache.commons.lang3.tuple.Pair<org.bouncycastle.cert.ocsp.OCSPResp, Long> requestOCSPResponse(String url,
 org.bouncycastle.cert.ocsp.OCSPReq ocspReq)
                                                                                                          throws IOException

Faz a requisição para o servidor OCSP presente na URL dada

Parameters:

url - A URL do servidor OCSP

ocspReq - A requisição a ser enviada

Returns:

A resposta do servidor OCSP e o tamanho da resposta

Throws:

IOException - Exceção em caso de má formação da requisição

getOCSPURL

public static String getOCSPURL(Object certificate)
                         throws AIAException

Busca a URL do servidor OCSP presente na AIA do certificado dado

Parameters:

certificate - Certificado a ser analisado

Returns:

A URL do servidor OCSP identificada na AIA do certificado

Throws:

AIAException - Exceção em caso de má formação da AIA do certificado

ocspB64ToOCSP

public static Optional<org.bouncycastle.asn1.ocsp.BasicOCSPResponse> ocspB64ToOCSP(String ocspB64)

ocspRespsToBasicOCSPResponses

public static Collection<org.bouncycastle.asn1.ocsp.BasicOCSPResponse> ocspRespsToBasicOCSPResponses(Collection<org.bouncycastle.cert.ocsp.OCSPResp> ocsps)

Converte todos os objetos OCSPResp de uma coleção para BasicOCSPResponse. Isso é feito para padronizar a resposta obtida, visto que o servidor OCSP pode retornar a resposta OCSP tanto como OCSPResp quanto como BasicOCSPResponse.

Parameters:

ocsps - coleção de OCSPResp a ser convertida para BasicOCSPResponse

Returns:

coleção de objetos convertidos para BasicOCSPResponse
