SRP-6a (RFC 5054 compatatible)
SRP6KeyPair srp6ClientAgree(in string identifier, in string password, in string group_id, in string hash_id, ref const Vector!ubyte salt, ref const BigInt B, RandomNumberGenerator rng);
- Parameters
string identifier the username we are attempting login for string password the password we are attempting to use string group_id specifies the shared SRP group string hash_id specifies a secure hash function Vector!ubyte salt is the salt value sent by the server BigInt B is the server's public value RandomNumberGenerator rng is a random number generator - Returns
- (A,K) the client public key and the shared secret key
SRP6a Client side
BigInt generateSrp6Verifier(in string identifier, in string password, ref const Vector!ubyte salt, in string group_id, in string hash_id);
- Parameters
string identifier a username or other client identifier string password the secret used to authenticate user Vector!ubyte salt a randomly chosen value, at least 128 bits long string group_id specifies the shared SRP group string hash_id specifies a secure hash function
Generate a new SRP-6 verifier
string srp6GroupIdentifier(ref const BigInt N, ref const BigInt g);
- Parameters
BigInt N the group modulus BigInt g the group generator - Returns
- group identifier
Return the group id for this SRP param set, or else thrown an exception
class SRP6ServerSession;
Represents a SRP-6a server session
ref const(BigInt) step1(ref const BigInt v, in string group_id, in string hash_id, RandomNumberGenerator rng);
- Parameters
