4.5 Authentication and Credentials

In GnuTLS every key exchange method is associated with a credentials type. So in order to enable to enable a specific method, the corresponding credentials type should be initialized and set using gnutls_credentials_set. A mapping is shown below.

Key exchange algorithms and the corresponding credential types:

Key exchange	Client credentials	Server credentials
`KX_RSA`
`KX_DHE_RSA`
`KX_DHE_DSS`
`KX_RSA_EXPORT`	`CRD_CERTIFICATE`	`CRD_CERTIFICATE`
`KX_SRP_RSA`	`CRD_SRP`	`CRD_SRP`
`KX_SRP_DSS`		`CRD_CERTIFICATE`
`KX_SRP`	`CRD_SRP`	`CRD_SRP`
`KX_ANON_DH`	`CRD_ANON`	`CRD_ANON`
`KX_PSK`	`CRD_PSK`	`CRD_PSK`
