Class ExpiringTimestampNonceServices

java.lang.Object

org.springframework.security.oauth.provider.nonce.ExpiringTimestampNonceServices

All Implemented Interfaces:

OAuthNonceServices

public class ExpiringTimestampNonceServices
extends Object
implements OAuthNonceServices

Nonce services that only validates the timestamp of a consumer request. The nonce is not checked for replay attacks. The timestamp is interpreted as the number of seconds from January 1, 1970 00:00:00 GMT. If the timestamp is older than the configured validity window, the nonce is not valid. The default validity window is 12 hours.

Method Detail

validateNonce

public void validateNonce(ConsumerDetails consumerDetails,
                 long timestamp,
                 String nonce)
                   throws org.springframework.security.core.AuthenticationException

Description copied from interface: OAuthNonceServices

Validate a nonce for a specific consumer timestamp. This is an opportunity to prevent replay attacks. Every nonce should be unique for each consumer timestamp. In other words, this method should throw a BadCredentialsException if the specified nonce was used by the consumer more than once with the specified timestamp.

Specified by:

validateNonce in interface OAuthNonceServices

Parameters:

consumerDetails - The consumer details.

timestamp - The timestamp.

nonce - The nonce.

Throws:

org.springframework.security.core.AuthenticationException - If the nonce failed to validate.

getValidityWindowSeconds

public long getValidityWindowSeconds()

Set the timestamp validity window (in seconds).

Returns:

the timestamp validity window (in seconds).

setValidityWindowSeconds

public void setValidityWindowSeconds(long validityWindowSeconds)

The timestamp validity window (in seconds).

Parameters:

validityWindowSeconds - the timestamp validity window (in seconds).
