The DSA/DSS Ruby library can be used in applications and websites to create and verify DSA signatures and keys.

The Digital Signature Algorithm (DSA) is a United States Federal Government standard (or FIPS) for digital signatures. It was proposed by the National Institute of Standards and Technology (NIST) for use in their Digital Signature Standard (DSS)

DSA Library Features

Note: The Digital Signature Algorithm (DSA) is synonomous with the Digital Signature Standard (DSS)
