# QSsl Namespace Reference
[QtNetwork module]

The QSsl namespace declares enums common to all SSL classes in QtNetwork. More...

     #include <QSsl>

This namespace was introduced in Qt 4.3.

### Types

- enum AlternateNameEntryType { EmailEntry, DnsEntry }
- enum EncodingFormat { Pem, Der }
- enum KeyAlgorithm { Rsa, Dsa }
- enum KeyType { PrivateKey, PublicKey }
- enum SslProtocol { SslV3, SslV2, TlsV1, UnknownProtocol, AnyProtocol }

## Detailed Description

The QSsl namespace declares enums common to all SSL classes in QtNetwork.

## Type Documentation

### enum QSsl::AlternateNameEntryType

Describes the key types for alternate name entries in QSslCertificate.

Constant | Value | Description
--- | --- | ---
`QSsl::EmailEntry` | `0` | An email entry; the entry contains an email address that the certificate is valid for.
`QSsl::DnsEntry` | `1` | A DNS host name entry; the entry contains a host name entry that the certificate is valid for. The entry may contain wildcards.

See also QSslCertificate::alternateSubjectNames().

### enum QSsl::EncodingFormat

Describes supported encoding formats for certificates and keys.

Constant | Value | Description
--- | --- | ---
`QSsl::Pem` | `0` | The PEM format.
`QSsl::Der` | `1` | The DER format.

### enum QSsl::KeyAlgorithm

Describes the different key algorithms supported by QSslKey.

Constant | Value | Description
--- | --- | ---
`QSsl::Rsa` | `0` | The RSA algorithm.
`QSsl::Dsa` | `1` | The DSA algorithm.

### enum QSsl::KeyType

Describes the two types of keys QSslKey supports.

Constant | Value | Description
--- | --- | ---
`QSsl::PrivateKey` | `0` | A private key.
`QSsl::PublicKey` | `1` | A public key.

### enum QSsl::SslProtocol

Describes the protocol of the cipher.

Constant | Value | Description
--- | --- | ---
`QSsl::SslV3` | `0` | SSLv3 - the default protocol.
`QSsl::SslV2` | `1` | SSLv2
`QSsl::TlsV1` | `2` | TLSv1
`QSsl::UnknownProtocol` | `-1` | The cipher's protocol cannot be determined.
`QSsl::AnyProtocol` | `3` | The socket understands SSLv2, SSLv3, and TLSv1. This value is used by QSslSocket only.
