According to Secure digital xml electronic signature it is
important to understand the
cryptographic signatures are much more than an error checking
technique akin to checksum algorithms, or even high
reliability error detection and correction algorithms such
as Reed-Solomon. In addition, no message
integrity protocols include error correction, for to do so would destroy
the tampering detection feature, Secure digital xml electronic
signature.
Popular
electronic signature standards include the Open-PGP standard
supported by PGP and Gnu-PG, and some of the S/MIME standards (available
in Microsoft Outlook). All current cryptographic digital signature
schemes require that the recipient have a way to obtain the sender's
public key with assurances of some kind that the public key and sender
identity belong together, and message integrity measures (also
digital
signatures) which assure that neither the attestation nor the value
of the public key can be surreptitously changed, Secure digital xml
