Method Detail

constructSignatureForRequestParameters

public static void constructSignatureForRequestParameters(java.util.List<org.apache.http.NameValuePair> params,
                                                          java.lang.String secretKey)

Signs a set of request parameters.

Generates additional parameters to represent the timestamp and generated signature. Uses the supplied pre-shared secret key to generate the signature.

Parameters:

params - List of NameValuePair instances containing the query parameters for the request that is to be signed

secretKey - the pre-shared secret key held by the client

constructSignatureForRequestParameters

protected static void constructSignatureForRequestParameters(java.util.List<org.apache.http.NameValuePair> params,
                                                             java.lang.String secretKey,
                                                             long currentTimeSeconds)

Signs a set of request parameters.

Generates additional parameters to represent the timestamp and generated signature. Uses the supplied pre-shared secret key to generate the signature.

Parameters:

params - List of NameValuePair instances containing the query parameters for the request that is to be signed

secretKey - the pre-shared secret key held by the client

currentTimeSeconds - the current time in seconds since 1970-01-01

verifyRequestSignature

public static boolean verifyRequestSignature(javax.servlet.http.HttpServletRequest request,
                                             java.lang.String secretKey)

Verifies the signature in an HttpServletRequest.

Parameters:

request - The HttpServletRequest to be verified

secretKey - The pre-shared secret key used by the sender of the request to create the signature

Returns:

true if the signature is correct for this request and secret key.

verifyRequestSignature

protected static boolean verifyRequestSignature(javax.servlet.http.HttpServletRequest request,
                                                java.lang.String secretKey,
                                                long currentTimeMillis)

Verifies the signature in an HttpServletRequest.

Parameters:

request - The HttpServletRequest to be verified

secretKey - The pre-shared secret key used by the sender of the request to create the signature

currentTimeMillis - The current time, in milliseconds.

Returns:

true if the signature is correct for this request and secret key.
