Examples of SRP6CryptoParams

com.nimbusds.srp6.SRP6CryptoParams
The crypto parameters for the SRP-6a protocol. These must be agreed between client and server before authentication and consist of a large safe prime 'N', a corresponding generator 'g' and a hash function algorithm 'H'.
The practical approach is to have the server manage these and make them available to clients on request. This way, the client does not need to anticipate or otherwise keep track of which parameters are used for which users or servers; it only needs to verify their validity, which can be done mathematically or by simple table lookup.
For convenience this class includes a set of precomputed parameters. @author Vladimir Dzhuvinov
