This code snippet shows interoperability between wodCrypt (signs data) and NET C# code (verifies signature).

Code to sign text ABCD with key stored as XML (so can be loaded by C#):

[code] Dim k As New Keys
k.FromXmlString ( <RSAKeyValue><Modulus>26NtFkEYNumpdM9/1Ie+TnoBaOCi6ZtGdrfFcFP7Aq/0zSt2iLPeu1mIwpO4x445mdsm3D+R5fgF/5bdSXPmh7QpeElG5GbkCO6YnLRoktOLu2TtEME59ripyMVeM8xahJj+8BnkKsZrwj2mPFlYxmc+DBIuRGm3f8FfDf5kpmc=</Modulus><Exponent>AQAB</Exponent><P>7p6tANYwpDzObpAq5sJiBJA01DuDA89ZpcO6t3JGf8q+kp5gcq5sgwfqVvxHgjCP3kN1IdXLs4zLVjVm+VGpfQ==</P><Q>66LSIRclT3mcWJkqiRj3gxeKIuQZ6KyPMJZqZGGcp3uwHblJr1bJrlLsqz2RwDdnmIhuEWM5gOCdl93lQ8D0sw==</Q><DP>oJ5qcY+7ujG7+qxMVHwvoka3aMyOSfg+rdfsTSM81TRRxzuYTFmgbSrc0KSMNdQeY0whAh95OGjjTiowIE6ZuQ==</DP><DQ>OWtpzQp42w8FXEmmpdXhqp432RzAe4RhODPPJTrsE5v+ZJ/cJs/9QW+PoILWW4KkyfSk7bPCNXeGr5Uw4vvIJQ==</DQ><InverseQ>K/ekbIbFzWufoBbhJz1U/8+XWXCei5og/tWyhvWLsaFnushtRzU8k92/VI9F+CHtHoEjwHtZaalRNoL1zoVvxQ==</InverseQ><D>Sky8qFyY7mqZEpTnL2REMpP/ShVDxzbp3VtJhThDn6MacxWS4afHXyVoqDoEti0cuzlxqewvVNZUYSQN870rbHhMivKOzyuTcP7yG+/Kvmk31LroV5jOOjAmtLyzt5hAdTDg9UBmweJzeL//aH3oNHkOhVj3KczDJXmRFRhqwbE=</D></RSAKeyValue> )
