memory-hard hashing function - runtime library
Argon2 is a password-hashing function that can be used to hash passwords for credential storage, key derivation, or other applications.
There are two main versions of Argon2: Argon2i and Argon2d. Argon2i is the safest against side-channel attacks, while Argon2d provides the highest resistance against GPU cracking attacks.
Argon2i and Argon2d 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
This package includes the dynamic library against which programs are linked.
