Hi Andrea, First of all: the provided certificate has basic constraints set to critical with ca:false, so this certificate is not allowed to sign crls and so the verification fails.
To verify the CRL: 1. convert the certificate to PEM > openssl x509 -in certificate.der -inform DER in out certificate.pem 2. check it > openssl crl -in myacrl.der -inform DER -CAfile certificate.pem The verification fails because of BC=critical,ca:false Kind regards, Chris -- Christian Pohl secaron AG "Andrea Nagar" <[EMAIL PROTECTED]> schrieb im Newsbeitrag news:[EMAIL PROTECTED]. .. > I have a CRL file (mycrl.der) that has been signed > with a certificate whose public key is contained into > the (certificate.der) file.
