Digital Signature tools
Digital Signature :
An encrypted message digest which is appended to a plaintext or encrypted message to verify the identity of the sender. The signature is encrypted with the user's private key and can only be decrypted with the corresponding public key. The same key pairs may be used for signature and encryption purposes but separate key pairs for each purpose are usually recommended.
