Argon2
Description: Password hashing winner of PHC.
Outputs: Variable
Uses: Highest resistance against GPU cracking attacks, safest against side-channel attacks.

argon(argon2_js)
In this example We generate hash and validate password with argon2i from string Hello world! with t_cost, m_cost, parallelism and salt parameters given.
- On argon2_js["family"] can be one of {argon2i, argon2d, argon2id}
- On argon2_js["operation"] can be {hash, verify}
- ARGON2 only supports "type":"string"
Json to hash
{ "version": 1 , "algorithm":"ARGON2" ,"family":"argon2 flavor",
"plaintext": "your password","t_cost":INT,"m_cost":INT,"parallelism":INT,
"salt":"hex string","hashlen":INT, "hex": BOOL, "operation":"hash"}
Json to verify
{ "version": 1 , "algorithm":"ARGON2" ,"family":"argon2 flavor",
"plaintext": "your password","hex":BOOL,"pwd":"Hex (hash arong2 string) ",
"operation":"verify"}
In this tutorial We are protecting user's credentials with TLS and Argon2. It means the information is protected in motion, at rest, in use. End to end user credentials protection
