## Detailed Description

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

## Type Documentation

### 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().

### 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.

### 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.

### 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.

### 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.
