public class UArgon2 extends Object

Function Argon2

Inputs:
  1. password (P): Bytes (0..232-1) Password (or message) to be hashed
  2. salt (S): Bytes (8..232-1) Salt (16 bytes recommended for password hashing)
  3. parallelism (p): Number (1..224-1) Degree of parallelism (i.e. number of threads)
  4. tagLength (T): Number (4..232-1) Desired number of returned bytes
  5. memorySizeKB (m): Number (8p..232-1) Amount of memory (in kibibytes) to use
  6. iterations (t): Number (1..232-1) Number of iterations to perform
  7. version (v): Number (0x13) The current version is 0x13 (19 decimal)
  8. key (K): Bytes (0..232-1) Optional key (Errata: PDF says 0..32 bytes, RFC says 0..232 bytes)
  9. associatedData (X): Bytes (0..232-1) Optional arbitrary extra data
  10. hashType (y): Number (0=Argon2d, 1=Argon2i, 2=Argon2id)
Output:
tag: Bytes (tagLength) The resulting generated bytes, tagLength bytes long
