◆ isCA()
| bool QCA::Certificate::isCA | ( | ) | const |
Test if the Certificate is valid as a Certificate Authority.
- Returns
- true if the Certificate is valid as a Certificate Authority
- Examples
- certtest.cpp.
◆ isIssuerOf()
| bool QCA::Certificate::isIssuerOf | ( | const Certificate & | other | ) | const |
Test if the Certificate has signed another Certificate object and is therefore the issuer.
- Parameters

other the certificate to test
- Returns
- true if this certificate is the issuer of the argument

| bool QCA::Certificate::isNull | ( | ) | const |
Test if the certificate is empty (null)
- Returns
- true if the certificate is null
- Examples
- publickeyexample.cpp, sslservtest.cpp, and ssltest.cpp.
◆ isSelfSigned()
| bool QCA::Certificate::isSelfSigned | ( | ) | const |
Test if the Certificate is self-signed.
- Returns
- true if the certificate is self-signed
- Examples
- certtest.cpp.
◆ issuerInfo()
| CertificateInfo QCA::Certificate::issuerInfo | ( | ) | const |
Properties of the issuer of the certificate.
- See also
- subjectInfo for how the return value works.
- Examples
- certtest.cpp.
◆ issuerInfoOrdered()
| CertificateInfoOrdered QCA::Certificate::issuerInfoOrdered | ( | ) | const |
Properties of the issuer of the certificate, as an ordered list (QList of CertificateInfoPair).
This allows access to the certificate information in the same order as they appear in a certificate. Each pair in the list has a type and a value.
- See also
- issuerInfo for an unordered version
- subjectInfoOrdered for the ordered information on the subject
- CertificateInfoPair for the elements in the list
◆ issuerKeyId()
| QByteArray QCA::Certificate::issuerKeyId | ( | ) | const |
The key identifier associated with the issuer.
◆ issuerLocations()
| QStringList QCA::Certificate::issuerLocations | ( | ) | const |
List of URI locations for issuer certificate files.
Each URI refers to the same issuer file
◆ matchesHostName()
| bool QCA::Certificate::matchesHostName | ( | const QString & | host | ) | const |
Test if the subject of the certificate matches a specified host name.
This will return true (indicating a match), if the specified host name meets the RFC 2818 validation rules with this certificate.
If the host is an internationalized domain name, then it must be provided in unicode format, not in IDNA ACE/punycode format.
- Parameters
-
host the name of the host to compare to

The signature algorithm used for the signature on this certificate.
◆ subjectInfo()
| CertificateInfo QCA::Certificate::subjectInfo | ( | ) | const |
Properties of the subject of the certificate, as a QMultiMap.
This is the method that provides information on the subject organisation, common name, DNS name, and so on. The list of information types (i.e. the key to the multi-map) is a CertificateInfoType. The values are a list of QString.
An example of how you can iterate over the list is:
- Examples
- certtest.cpp.
◆ subjectInfoOrdered()
| CertificateInfoOrdered QCA::Certificate::subjectInfoOrdered | ( | ) | const |
Properties of the subject of the certificate, as an ordered list (QList of CertificateInfoPair).
This allows access to the certificate information in the same order as they appear in a certificate. Each pair in the list has a type and a value.
