Syntax
QByteArray ExportCert(const QString& qsPassword, int iFormat, bool bExportKey);

ExportKey specifies whether to export the private key together with the certificate. Pass the encryption password via the Password parameter if needed.
| cfmUnknown | 0 | Unknown certificate format |
| cfmDER | 1 | DER file format. Applicable to certificates, certificate requests, private keys. Encryption not supported |
| cfmPEM | 2 | PEM file format. Applicable to certificates, certificate requests, private keys. Encryption supported for private keys. |
| cfmPFX | 3 | PFX/PKCS#12 file format. Applicable to certificates. Encryption supported. |
| cfmSPC | 4 | SPC file format. Applicable to certificates. Encryption not supported. |
| cfmPVK | 5 | PVK file format. Applicable to private keys. Encryption not supported. |
| cfmPKCS8 | 6 | PKCS#8 file format. Applicable to private keys. Encryption supported. |
