hi everybody,

I am doing a project based on watermarking. for that i have to use ECDSA algorithm to implement it to generate a digital signature for the image which i use as cover image. I have now obtained the hash values using Sha 512 of both the cover image and the text document which has the secret info to be passed. Now what crypto service provider should i use to implement ECDSA and after getting the cryptoservice provider how should i do? where will i get that crytoApI

The current release of the Bouncy Castle provider supports SHA512withECDSA.

Regards,

David
