%description
Argon2 is a password-hashing function that summarizes the state of the art in the design of 
memory-hard functions and can be used to hash passwords for credential storage, key derivation, 
or other applications.

It has a simple design aimed at the highest memory filling rate and effective use of multiple 
computing units, while still providing defense against tradeoff attacks (by exploiting the 
cache and memory organization of the recent processors).

Argon2 has three variants: Argon2i, Argon2d, and Argon2id. Argon2d is faster and uses data-depending 
memory access, which makes it highly resistant against GPU cracking attacks and suitable for 
applications with no threats from side-channel timing attacks (eg. cryptocurrencies). Argon2i 
instead uses data-independent memory access, which is preferred for password hashing and 
password-based key derivation, but it is slower as it makes more passes over the memory to 
protect from tradeoff attacks. Argon2id is a hybrid of Argon2i and Argon2d, using a combination 
of data-depending and data-independent memory accesses, which gives some of Argon2i's resistance 
to side-channel cache timing attacks and much of Argon2d's resistance to GPU cracking attacks.

Argon2i, Argon2d, and Argon2id are parametrized by:

- A time cost, which defines the amount of computation realized and therefore the execution 
time, given in number of iterations
- A memory cost, which defines the memory usage, given in kibibytes
- A parallelism degree, which defines the number of parallel threads
