Please note that, public key and a corresponding private key form a keypair. So, if I sign a someone else's public key with my secret key, then the encrypted key cannot be decrypted with someone else's public key. It would need my public key only. And, if someone decrypts it with my public key, he would know the public key that he has used in the decryption and the decrypted public key that he has got does not match.A Mitrahttp://www.blogger.com/profile/03677902287909326838noreply@blogger.comtag:blogger.com,1999:blog-7382953222001096250.post-11534959275228425292016-10-25T15:29:42.755+05:302016-10-25T15:29:42.755+05:30Regarding "Registration of a Public Key"...Regarding "Registration of a Public Key", does not the 'entity' have to be authenticated as a prerequisite for the registration to work?
