## Detailed Description

The QSslError class provides an SSL error.

QSslError provides a simple API for managing errors during QSslSocket's SSL handshake.

## Method Documentation

### QSslError.__init__ (self)

Constructs a QSslError object with no error and default certificate.

### QSslError.__init__ (self, SslError error)

Constructs a QSslError object. The argument specifies the error that occurred.

### QSslError.__init__ (self, SslError error, QSslCertificate certificate)

Constructs a QSslError object. The two arguments specify the error that occurred, and which certificate the error relates to.

See also QSslCertificate.

### QSslError.__init__ (self, QSslError other)

Constructs an identical copy of other.

### QSslCertificate QSslError.certificate (self)

Returns the certificate associated with this error, or a null certificate if the error does not relate to any certificate.

See also error() and errorString().

### SslError QSslError.error (self)

Returns the type of the error.

See also errorString() and certificate().

### QString QSslError.errorString (self)

Returns a short localized human-readable description of the error.

See also error() and certificate().

### bool QSslError.__eq__ (self, QSslError other)

### bool QSslError.__ne__ (self, QSslError other)
