Description copied from interface: OAuthSignatureMethod

Returns the name of this signature method, as negotiated through the OAuth protocol.

Specified by:

name in interface OAuthSignatureMethod

sign

public String sign(String elements,
                   OAuthSecrets secrets)
            throws InvalidSecretException

Generates the RSA-SHA1 signature of OAuth request elements.

Specified by:

sign in interface OAuthSignatureMethod

Parameters:

elements - the combined OAuth elements to sign.

secrets - the secrets object containing the private key for generating the signature.

Returns:

the OAuth signature, in base64-encoded form.

Throws:

InvalidSecretException - if the supplied secret is not valid.

verify

public boolean verify(String elements,
                      OAuthSecrets secrets,
                      String signature)
               throws InvalidSecretException

Verifies the RSA-SHA1 signature of OAuth request elements.

Specified by:

verify in interface OAuthSignatureMethod

Parameters:

elements - OAuth elements signature is to be verified against.

secrets - the secrets object containing the public key for verifying the signature.

signature - base64-encoded OAuth signature to be verified.

Returns:

true if the signature matches the secrets and data.

Throws:

InvalidSecretException - if the supplied secret is not valid.
