Efficient digital e-sign solutions
Standard (DSS) is the
digital signature
algorithm (DSA) developed by the U.S. National Security Agency (NSA) to
generate a digital signature for the authentication of electronic
documents. DSS was put forth by the National Institute of Standards and
Technology (NIST) in 1994, and has become the United States government
standard for authentication of
electronic
documents.

DSS is specified in Federal Information Processing Standard (FIPS) 186.

DSA is a pair of large numbers that are
computed according to the specified algorithm within parameters that
enable the authentication
of the signatory, and as a consequence, the integrity of the data
attached. Digital signatures are generated through DSA, as well as
verified. Signatures are generated in conjunction with the use of a
private key; verification takes place in reference to a corresponding
public key. Each signatory has their own paired public (assumed to be
known to the general public) and private (known only to the user) keys.
Because a signature can only be generated by an authorized person using
their private key, the corresponding public key can be used by anyone to
verify the

A data summary of the information (called a message digest) is created
through the use of a hash function (called the Secure Hash Standard, or
SHS, and specified in FIPS 180). The data summary is used in conjunction
with the DSA algorithm to create the
digital signature
that is sent with the message.

verification involves the use of the same hash function.
