ABSTRACT:
A method and system for deploying a suite of advanced cryptographic algorithms that includes: providing a legacy cryptographic interface that is associated with a legacy operating system and a legacy application, and supports a suite of legacy cryptographic algorithms; providing a suite of advanced cryptographic algorithms that includes one or more of an advanced asymmetric key algorithm, an advanced symmetric key algorithm, and/or an advanced hash function; providing an advanced cryptographic interface that is independent of the legacy operating system and the legacy application, backwards compatible with the legacy cryptographic interface, and capable of supporting the suite of advanced cryptographic algorithms; and transparently and automatically substituting the suite of advanced cryptographic algorithms for the legacy cryptographic algorithms through the invocation of the advanced cryptographic interface at the time of an initial performance of encrypting, hashing, digitally signing the hash of, decrypting, re-hashing, and/or validating the digital signature of an item.
